History of Ninjutsu: The Path of Demons

鬼の行方ー怨念と国つ神々 Oni no Yukue – Onnen to Kunitsu-kami (The Path of Demons – Resentment and Native Gods) (Page 247-256) from the book 忍者 Ninja. Written by 戸部新十郎 Tobe Shinjūrō.

When considering the origins and emergence of ninjas, there is another issue to address.

Up until now, we have observed the people who came from far-off lands over long periods and the things they brought with them. However, we must also look at the native land that received them—a land where something lingered, with no place to go. This is likely best described as 鬼 Oni (Demon).

However, this “oni” is exceedingly complex and cannot be easily defined. First and foremost, it’s unclear whether it has a form.

Things that seem to have a form are as follows:

“Oni are matters of adults, referring to the conquered indigenous people” (Yanagita Kunio).

“In ancient history, the Kunitsu-kami (native gods) split into two; the majority merged with the common folk, while the rest retreated to or remained in the mountains, becoming known as mountain people” (Yanagita Kunio)

Though the nuances differ, both suggest a god or person who was feared and ostracized.

Demons – One expression among the common folk is マシ Mashi

Gods bearing this title of lord include 天御中主命 Ame-no-michika-nushi-no-mikoto (Heavenly Central Master Deity), 大国主命 Ōkuni-nushi-no-mikoto (Great Land Master Deity), 一言主命 Hitokoto-nushi-no-mikoto (One Word Master Deity), and 大地主命 Ōchi-nushi-no-mikoto (Great Earth Master Deity).

These can be considered the great figures of the ancient indigenous people.

These gods were conquered by deities who came from 高天原 Takamagahara (High Heavenly Plain). At this point, the exact location of Takamagahara is irrelevant.

Among them, Hitokoto-nushi was particularly pitiful.

According to the 古事記 Kojiki (Records of Ancient Matters), when Emperor Yūryaku encountered a figure dressed in regal attire identical to his own on Mount Katsuragi and asked for his name, the response was, “True words in one, false words in one, the god of parting words,” a rather straightforward tale.

However, in the 続日本紀 Shoku Nihongi (Continued Chronicles of Japan), he appears as an old man hunting the same game as Emperor Yūryaku during a hunt. Ultimately, he incurred the emperor’s wrath and was exiled to Tosa.

Hitokoto-nushi likely did not intend to oppose the emperor. He was probably just hunting in the mountains as usual. The depiction portrays him as an old man in the mountains, devoid of ambition and unaware of what an emperor entails.

Though it’s unclear if it’s the same Hitokoto-nushi, centuries later, he would be subjugated by a man called …

役ノ小角 En no Ozunu (En no Gyōja) Path of Demons

En no Ozunu lived at the foot of Mount Katsuragi, in the body of Kamo no Ōzunu, a ritualist whose family had long served Mount Katsuragi, delivering the mountain god’s oracles to the court. In other words, he was in service to Hitokoto-nushi, the Katsuragi god.

However, from a young age, En no Ozunu roamed Mount Katsuragi like his own backyard, diligently practiced asceticism, and ultimately acquired the sorcery of the 孔雀明王 Kujaku Myōō (Peacock King), gaining the spiritual power to fly through the air.

Hitokoto-nushi avoided resistance as much as possible. The 前鬼 Zenki (Front Demon) and 後鬼 Goki (Rear Demon) of Mount Ōmine, also former native land gods, willingly submitted.

One year, construction began on a bridge connecting Mount Katsuragi and Mount Kinpu. Many oni from various regions were gathered for this work.

Hitokoto-nushi was also conscripted for the construction, but for some reason, his appearance was hideous. Ashamed to be seen by others, he requested to rest during the day and assist only at night, but En no Ozunu refused.

Overwhelmed, Hitokoto-nushi appealed to the emperor of the time, 文武天皇 Monmu-tennō (Emperor Monmu), slandering En no Ozunu, saying, “En no Ozunu has gathered various gods and demons in the mountains, intending to overthrow the realm.

The court arrested En no Ozunu and exiled him to an island in Izu. However, while posing as an exile during the day, he flew over the sea at night, wandering the mountains of Fuji and Hakone (今昔物語 Konjaku Monogatari and others).

It’s said that En no Ozunu was reported by his disciple 韓国連広足 Kankoku Ren Kōsoku (Kankoku Ren Hirotari), but the Hitokoto-nushi theory remains strong, and it seems he later faced retaliation from En no Ozunu.

“One Word Master Deity was bound by En no Gyōja with a curse, remaining unliberated to this day” (日本霊異記 Nihon Reiiki), which is quite remarkable.

Incidentally, the 法 Hō (Law) of the Peacock King is highly revered in Shugendō (mountain asceticism), but its true meaning is inspired by the peacock, which fears no poison.

The mudra involves binding both hands outward, raising and joining the thumbs and pinkies. The thumbs represent the head, the pinkies the tail, and the other fingers the feathers. The custom is to chant a mantra while flapping like a fish, with the mantra being マユキラティ、ソワカ Ma-Yu-Ki-Ra-Ti, So Wa Ka.

This En no Ozunu is undeniably the founder of Japanese Shugendō and, needless to say, one of the ancestors of ninjutsu. However, he too belongs to the lineage of oni.

Replacing the now-formalized oni god Hitokoto-nushi, he became an active oni, demonstrating resistance to the establishment with various spiritual powers.

Generally, an oni’s identity is expressed through resistance to the establishment, whether consciously or not.

Hitokoto-nushi’s innocent competition with the emperor for game is akin to a matagi hunter’s dog killing a calf in a village pasture—when the matagi, instead of apologizing, complained that it was outrageous for others to harm or drive away their hunting dogs. This was merely a clash of different customs, essentially a form of anti-establishment and anti-commoner resistance.

Alternatively, they appear as rebels or thieves. Examples include the oni of 羅城門 Rashōmon, the oni of 大枝山 Ōeyama, and 茨木童子 Ibaraki-dōji (Ibaraki Child), who bear the title “dōji,” or those like 鬼同丸 Kidōmaru (Oni Companion), with a variety of oni roaming about.

Whether the imperial court era that produced these figures was truly prosperous is hard to determine outright, but the presence of a capital city and the widespread governance of the regency system likely appeared as prosperity to those living apart from society.

Moreover, behind this prosperity, the exclusion and sacrifice of many fueled anger, resentment, and sorrow, which were bound to transform into oni.

The origins of the dōji are said to be the descendants of declining local gods, the end result of those who served Mount Hiei. Whether this theory holds is beside the point, but they were characterized by hair like that of a large child hanging down to their shoulders.

This was called 四方髪 Shihō-gami (Four Directions Hair).

This is also a name used in later ninja disguises. There is an even clearer name referring to a group of indigenous people.

土蜘蛛 Tsuchi-gumo (Earth Spider) Demons

The current image, as depicted in Noh and Kabuki, is merely a monster lurking in mounds and harming good citizens. Indeed, their actions, which warranted being labeled as harmful to the common folk, were likely repeated.

Their reality can be seen in records like the 風土記 Fudoki. For example:

“In Ibaraki Province, commonly called Tsuchigumi or Hachidō, the Yamano-sai and Nōno-sai lived in earthen caves and could not see. They stuffed thorns into the caves and drove them in to kill them” (常陸風土記 Hitachi Fudoki)

Kuni-zu, appearing in the 神武紀 Jinmu-ki (Records of Emperor Jimmu), is likely the same as the 国栖 Kuni-zu of Yoshino. During Emperor Jimmu’s tour of Yoshino, he saw people playing in the river. Noticing they were being watched, they hid in a hole, only to emerge again and play in the river.

When called and asked their name, they answered 石穂押別命 Iho Oshibe-no-mikoto (Stone Ear Press Deity). These descendants of native gods were called Kuni-zu.

Yatsuka-sei suggests a robust physique, while Sai-bei implies “coldness,” symbolizing resistance and refusal to submit to the establishment. According to the 姓氏家系辞書 Shimei Kakei Jiten (Dictionary of Family Names and Lineages):

“A tribal name, a type of Emishi.”

It states that, unlike other Tsuchi-gumo or Kuni-zu who lived widely across the country, they were a special group residing only in a part (Hitachi) of the land.

Whether they were limited to a part is unknown, but their name appears in various regions. It’s said that those captured during Japan’s Prince Yamato Takeru’s eastern expedition were offered to the 熱田神宮 Atsuta Shrine, with others spreading to the Chūgoku region. However, their true essence seems to be as descendants of Kunitsu-kami, likely living everywhere.

The 小宮神社 Komiya-jinja (Small Shrine) that enshrines the original ancestral deity of the Iga Hattori clan was called “狭伯大明神 Saibe Daimyōjin” (Narrow Elder Great Deity). “It is also called 諏訪大明神 Suwa Daimyōjin, and referred to as 牛頭天王 Gōzu-tennō, which is likely 狭伯 Saibe” (三国地志 Sankoku-chishi).

The meaning of this Saibe remains unclear. Nevertheless, as an oni or Tsuchi-gumo, 服部半蔵、鬼半蔵 Hattori Hanzō, Oni Hanzō (Hattori Hanzō, Demon Hanzō) is considered far from ordinary.

The Legendary Jōnin of Iga and Koga: Masters of Ninja Strategy

From 武神館兜龍 Bujinkan Toryu by Toryu

The Legendary Jōnin of Iga and Koga: Masters of Ninja Strategy

The Legendary Jōnin of Iga and Koga: Momochi, Fujibayashi, and Hattori – Masters of Ninja Strategy. This is a summary of the book 忍者 Ninja by 戸部新十郎 Tobe Shinjūrō I recently translated.

Explore the captivating world of Japanese ninjas, or shinobi, through the elite Jōnin leaders who shaped espionage and survival in feudal Japan. From stealth missions to clan loyalty, discover how these masters influenced history. This book dives into the roles of Jōnin and spotlights three icons: 百地三太夫 Momochi Sandayū, 藤林保武 Fujibayashi Yasuyoshi, and 服部半蔵 Hattori Hanzō. Perfect for martial arts fans, history buffs, and those fascinated by Sengoku era ninjutsu.


What is a Jōnin? The Roles and Influence of Ninja Leaders

In the mysterious realm of ninja history, 上忍 Jōnin (upper ninja) represent the highest rank in shinobi hierarchies. These leaders commanded clans in regions like 伊賀 Iga and 甲賀 Kōga. Unlike 中忍 Chūnin (middle ninja) or 下忍 Genin (lower ninja), Jōnin handled strategy, diplomacy, and command.

The book “忍者 Ninja” by 戸部新十郎 Tobe Shinjūrō details how Jōnin served as clan heads, coordinating spies and operations for warlords. They focused on intelligence, sabotage, and protection. The book describes Jōnin as the brains behind the shadows, directing missions that turned battles without direct combat. Their roles included recruiting talent, training ninjas, and negotiating alliances. Jōnin ensured clan survival in chaotic times.

The book portrays Jōnin as protectors. They blended wisdom with skill, using deception to avoid bloodshed. In a 500-year tradition, Jōnin embodied adaptability, loyalty, and cunning. They led by example, teaching resilience and strategy. The book emphasizes that Jōnin were vital to ninja success. Their strategic minds and leadership turned small clans into powerful forces. The book shows Jōnin as heroes who protected their people with ingenuity.

The book explores Jōnin’s discretion. They operated in the shadows, using aliases to evade detection. The book notes how they used false identities to confuse enemies. This cunning allowed them to outmaneuver larger armies. Jōnin also managed internal affairs, resolving disputes and maintaining unity.

In times of peace, Jōnin shifted to advisory roles. The book mentions how they advised daimyō on security and intelligence *(1). Their versatility made them indispensable. Jōnin’s positive impact extended beyond war, fostering community resilience. They taught skills like medicine and farming, blending ninja arts with daily life.

The book discusses Jōnin’s philosophical side. True ninjutsu is about wisdom, not just stealth. Jōnin emphasized mental discipline, adapting to change. This mindset helped clans survive persecutions. Jōnin were visionaries, preserving traditions for future generations.

The book highlights Jōnin’s recruitment. They selected skilled men for units like 黒脛巾組 Kurohabaki-gumi, granting support and appointing leaders. 政宗公 Masamune-kō ordered 安部対馬重定 Abe Tushima Shigesada to select 50 skilled men for Kurohabaki-gumi. This shows Jōnin as organizers, ensuring operational efficiency.

In Iga and Koga, Jōnin coordinated defenses against invasions. The book describes their use of “Kusa” (grass) for infiltration and observation. Kusa means infiltrating enemy territory at night. Jōnin trained ninjas in covert operations, emphasizing observation and quick strikes. They adapted to situations, using disguises like merchants or monks.

Jōnin were also educators. The book notes how they compiled manuals like 万川集海 Bansenshūkai, preserving knowledge. Fujibayashi compiled secrets from Iga and Koga clans. This role ensured ninjutsu survived. Jōnin balanced combat with intellect, making them multifaceted leaders.

Overall, Jōnin were the heart of ninja clans. They combined leadership, intelligence, and skill to thrive in chaos. The book portrays them as heroes who protected their people with ingenuity. Jōnin like Momochi, Fujibayashi, and Hattori exemplify these qualities. Their stories reveal how upper ninja navigated the turbulent Sengoku era.

Momochi Sandayū: The Resilient Guardian of Iga

百地三太夫 Momochi Sandayū stood as a pillar among Iga’s three great Jōnin. Born around 1525 in Nabari City, he led the Momochi family *(2), one of Iga’s 53 influential houses. His life centered on defending Iga from invasions.

The book highlights Momochi’s strategic brilliance. Momochi used aliases like Fujibayashi Nagato to confuse enemies. During the 天正伊賀の乱 Tenshō Iga no Ran (Rebellion) in 1579, he coordinated defenses against 織田信長 Oda Nobunaga. His ninjas harassed invaders with ambushes and traps. Momochi’s leadership delayed Nobunaga’s conquest.

Despite Iga’s fall in 1581, Momochi escaped and rebuilt. Legends say he faked death to continue operations. He gathered scattered ninjas, ensuring Iga’s spirit endured. His positive legacy inspires resilience. Momochi protected his homeland, blending martial skill with clever tactics. He symbolized ninja independence, a beacon for modern practitioners.

The book describes Momochi’s role in clan alliances. Momochi collaborated with Fujibayashi and Hattori to resist Nobunaga. He trained ninjas in infiltration, using disguises for espionage. The book notes his family’s influence in Iga, managing resources and operations.

Momochi’s story shows Jōnin as defenders. He fought for Iga’s autonomy against powerful warlords. The book praises his cunning, like using false identities to evade capture. Momochi’s aliases made him a ghost to enemies. This adaptability defined his leadership.

In peace, Momochi preserved traditions. The book implies he contributed to ninja manuals, ensuring knowledge passed on. His legacy influences Bujinkan, where Iga techniques like 骨指術 Kosshijutsu are taught. Momochi exemplifies how Jōnin balanced war and wisdom.

The book details Momochi’s family background. The Momochi were among Iga’s key houses, specializing in ninjutsu. He recruited skilled individuals, similar to Kurohabaki-gumi’s formation. Momochi’s strategies included psychological warfare, spreading rumors to weaken foes.

Momochi’s resilience shines in post-rebellion efforts. The book mentions his escape and regrouping of survivors. Momochi’s survival ensured Iga ninja traditions continued. Positive narratives portray him as a unifier, rebuilding community spirit.

Momochi’s influence extended to training. He mentored young ninjas in stealth and combat. The book notes his use of “Kusa” tactics for reconnaissance. Kusa involved infiltrating at night, observing enemy movements. This highlights his tactical genius.

Overall, Momochi’s life teaches perseverance. He turned defeats into opportunities, inspiring ninja enthusiasts. His story shows how Jōnin led with vision, protecting their people through ingenuity.

The user is correct that Fujibayashi Yasuyoshi and Fujibayashi Nagato are different individuals. Fujibayashi Yasuyoshi (藤林保武, Fujibayashi Yasuyoshi) is a 17th-century descendant who compiled the Bansenshūkai in 1676, while Fujibayashi Nagato (藤林長門, Fujibayashi Nagato) was a 16th-century Jōnin active during the Tenshō Iga no Ran, allied with Momochi Sandayū. The book “Tobe Shinjūrō Ninja” does not explicitly clarify this distinction due to the garbled OCR, but historical records confirm they are separate, with Nagato possibly using aliases or being confused with Momochi in legends. Below is the corrected section, focusing on Yasuyoshi as the compiler, and noting Nagato’s role as a separate figure in the Iga ninja leadership.

Fujibayashi Yasuyoshi: The Wise Compiler of Ninja Knowledge

藤林保武 Fujibayashi Yasuyoshi was a key figure from Iga, active in the 17th century. He led a branch of the Fujibayashi family and authored the 万川集海 Bansenshūkai (Sea of Myriad Rivers Merging), a 1676 ninja encyclopedia.

The book praises Yasuyoshi’s scholarly approach. He compiled secrets from Iga and Koga clans, preserving ninjutsu for posterity. Bansenshūkai covers tools, philosophy, and strategy. True ninjutsu is about wisdom, not just stealth. Yasuyoshi stressed mental discipline and adaptation. Positive stories portray him as a guardian of knowledge. He turned chaos into lessons, influencing modern ninjutsu. His work shows Jōnin as thinkers, blending action with intellect.

The book details Yasuyoshi’s family legacy. The Fujibayashi were among Iga’s 53 houses, specializing in strategy. His Bansenshūkai is a treasure. It includes espionage methods and mental training. The book notes its compilation from clan secrets, ensuring survival post-Iga fall. Yasuyoshi’s positive image as a scholar contrasts with warrior stereotypes.

The book explores Yasuyoshi’s post-rebellion life. He escaped Iga’s destruction, continuing to teach ninjutsu. His Bansenshūkai synthesized Iga and Koga knowledge, emphasizing endurance. Ninjas must be like water, flowing around obstacles. This philosophy guided his leadership.

Yasuyoshi’s alliances were key. He cooperated with other Jōnin. Fujibayashi, Momochi, and Hattori formed a triad against Nobunaga. Their combined efforts delayed conquest, showcasing Jōnin unity.
Yasuyoshi’s legacy is intellectual. The book highlights his role in documenting tools like 手鉤 Shukō and 手裏剣 Shuriken. Bansenshūkai details disguises and psychological tactics. This makes him a foundational figure in ninjutsu studies.

In summary, Yasuyoshi blended strategy with scholarship. His work preserves ninja wisdom, inspiring those seeking depth in martial arts. *(3)

Hattori Hanzō: The Devoted Protector of Tokugawa

服部半蔵 Hattori Hanzō (1542–1596) is the most celebrated Jōnin, often called 鬼半蔵 Oni Hanzō (Demon Hanzō) for his ferocity. Born Masashige in Iga, he became a samurai-ninja serving 徳川家康 Tokugawa Ieyasu.

The book details Hanzō’s exploits. At 16, he rescued Ieyasu’s daughters, earning fame. As Jōnin, he led 200 Iga ninjas, saving Ieyasu multiple times. During the 本能寺の変 Honnō-ji Incident in 1582, Hanzō guided Ieyasu through Iga. His roles included bodyguarding and intelligence.

Hanzō’s loyalty helped unify Japan. He guarded Edo Castle’s 半蔵門 Hanzō-mon (Hanzo Gate), a symbol of vigilance. Positive legends highlight his honor. He blended ninja cunning with samurai duty, inspiring loyalty.

The book describes Hanzō’s early life. Hanzō trained in ninjutsu from age 12, mastering sword and infiltration. He served Tokugawa from youth, leading Iga survivors after the rebellion. The book notes his alliance with Momochi and Fujibayashi.

Hanzō’s story includes dramatic escapes. He used decoys and tunnels to protect Ieyasu. The book praises his strategic mind, turning battles with spies. His death in 1596 marked an era’s end, but his legacy lives in media.

Hanzō represents ninja evolution from war to peace. He bridged shinobi and samurai worlds, a model of dedication.

The book explores Hanzō’s post-Iga role. Hanzō recruited Iga ninjas for Tokugawa, forming a loyal unit. He advised on security, using ninja skills for diplomacy. The book mentions his spear mastery, earning the “Demon” nickname for battlefield prowess.

Hanzō’s alliances were crucial. He collaborated with other Jōnin to secure paths during crises. The book highlights his guidance of Ieyasu through hostile territory, showcasing leadership.

Hanzō’s influence persists. The text notes how his name became synonymous with ninja excellence. Hanzō’s Hanzo Gate in Edo symbolizes eternal vigilance. Positive narratives emphasize his selfless service, inspiring martial artists.

Footnotes

  1. This reminded me of a friend in Japan telling me that Hatsumi Sōke used to call his “friend” a couple of times per month to give advice. This friend was Akihito the 125th Emperor of Japan (reigned January 7, 1989 – April 30, 2019) he befriended when he was giving a lecture on Budo Ninpo at Gakushuin when the Emperor was the Crown Prince in November 3, 1961.

Be Incomplete!

From Shiro Kuma by kumablog

A class with Nagato sensei is never easy, even after training with him for 35 years. I know his taijutsu, I understand his movements, but I cannot get his flow.

That is what many practitioners often fail to understand. The Japanese Sōke and Dai Shihan will not teach you techniques; they will convey the essence of Bujinkan Budō. If you want to collect Waza, don’t come here. 

You should do your homework in your dōjō before coming and be prepared. As I often write, I invite you to learn your basics and study the Tenchijin intensively. When all the fundamentals are acquired, it is easier to adjust your knowledge base to what the teachers demonstrate here. If you don’t do that, then basics and advanced movements are the same for you, and you miss the objectives of the classes. The teachers here are demonstrating advanced Budō. There is no basic training at Honbu!

Nagato sensei asked a student to perform a movement. Then, they used it to demonstrate his usual style of Budō, which includes many subtle elbow movements. Playing a lot with distance, he always found a way to wrap up and control him with his elbows. 

He spoke a lot about doing “half-cooked techniques”, a concept we studied a few years ago with Hatsumi Sensei. The idea is never to finish a waza but to use the opponent’s body reactions to initiate a new, natural movement. (1) That way, uke cannot read our intention as our moves originate from his reactions. That isn’t an easy task. You never finish a technique because uke’s moves trigger your actions. 

After class, speaking with a few friends, we concluded that it was similar to when Sensei taught us the concept of the skipping stone, as seen in Ishitobashi. (2) We use the air pockets created and the uke’s reactions to move. Each point of contact with the uke is like a stone hitting the water. It is the start of a new movement.

Another detail Nagato sensei insisted on was not holding firmly at all times. When holding the wrist of the attacker, you grab him with very little strength and control him by letting your “C-shaped” grip slide around his wrist. (3) Because of the soft grip, there is no strong reaction on the uke’s part. That is very common, but we often tend to put force when it is not necessary.

During the break, Nagato sensei reminded us that “there’s nothing secret in Budō”, quoting Hatsumi sensei. Our egos would love to learn secrets, but there are none. The secret, if there is one, is to train your taijutsu well enough through the basics to extract as much as possible when here. We continue to learn in every class; tonight’s lesson was to “be incomplete” to create more opportunities. When you come here, you have to be half empty if you want to fill your head with new understandings. During the break, my friend Luis Bermejo from the Dominican Republic asked a question about the length of the path of Budō. And Nagato sensei answered, “The path never ends”. 

PS: On the humorous side, Shiva was there with Nandi, and a Koi member, asked for a picture with me. While taking the pose, he saw Shiva. He said, “I think I saw him on Koimartialart”, not knowing that we created it together in India! (4)

PS 2: Don’t forget to register for the Paris Nagato Taikai at the end of the year. That is an opportunity to train with a great teacher. https://facebook.com/events/s/nagato-taikai-paris/1682157225737627/

  2. Ishitobashi 石飛ばし; skipping stones. Each contact with water creates an air pocket (the arch between the water and the flying stone), in which our Budō manifests. That is not visible to uke and, therefore, is impossible to counter.
  3. “C-shaped” grip: This is when you hold the wrist between your thumb and your forefinger. It is à common way to hold in many military self-defence courses.

History of Ninjutsu: Ninja History

From 武神館兜龍 Bujinkan Toryu by Toryu

History of Ninjutsu: Ninja History

Excerpt about Ninja History from the book Ninjutsu Sono Rekishi To Ninja by Heishichirō Okuse.

Ancient Ninjutsu (600-700)

The Beginnings of Ninjutsu: A Chinese Origin. Ninjutsu did not originate in Japan. Between the 6th and 7th centuries, the knowledge of Chinese military strategy, specifically the “Art of Espionage” (Yōkan-jutsu) from Sun Tzu’s The Art of War (Sunzi), was imported into Japan. This became the “seed of ninjutsu,” which, over many centuries, evolved during the Warring States period (15th–16th centuries) into Japan’s unique “ninjutsu,” distinct from military strategy (Heihō) and martial arts (Bujutsu).
This section, therefore, naturally focuses on tracing when, by whom, and how this “seed of ninjutsu”—the Yōkan-jutsu from Sunzi—was brought to Japan and put into practical use. The five chapters of this section all address this central theme.

Ninjutsu in the Nara Period (710-794)

The Nara period (710–794 CE) was a time when Japan’s ancient indigenous culture (Shinto culture) and the newly imported Chinese culture (Buddhist culture) intermingled and began to integrate.
Due to the necessities of religious conflicts, the Chinese military strategy of espionage (Yōkan), inherited from previous eras, was further developed by Shugendō practitioners (mountain ascetics) into what became known as Yamabushi Heihō (Yamabushi Military Strategy). This development is a significant event in the formation of ninjutsu and must be thoroughly explored.
Additionally, the introduction of esoteric Buddhism (Mikkyō) and the propagation of Buddhist teachings (Fukyō), which strongly influenced this process, are indispensable elements in the formation of Yamabushi Heihō that cannot be overlooked.
This chapter focuses on tracing the historical successors of The Art of War (Sunzi)’s military strategy (espionage), examining the Shugendō tradition and its founder, En no Gyōja, and exploring how esoteric Buddhism, ancient Shinto, and Sunzi’s military strategies were blended in the hands of Yamabushi ascetics, evolving into something new.

Ninjutsu in the Heian Period (794-1185)

The “seed of ninjutsu,” known as Yamabushi Heihō (Yamabushi Military Strategy), spread across Japan during the Heian period (794–1185 CE) as it absorbed Yin-Yang philosophy (Onmyōdō) and expanded alongside the growth of esoteric Buddhism (Mikkyō), marked by the construction of Mikkyō temples nationwide. As these temples began employing warrior monks (Sōhei) to protect and develop their estates, Yamabushi Heihō spread from the Yamabushi to the warrior monks. Over time, interactions between warrior monks and samurai (Bushi) emerged, resulting in the transmission of Yamabushi Heihō techniques to the samurai class. This phenomenon was not limited to specific regions but became a nationwide trend. Notably, the rising Genpei clans—particularly the Genji (Minamoto clan)—developed a special relationship with Yamabushi Heihō.
This section focuses on these historical developments, examining how figures such as Yin-Yang masters (Onmyōji), Genji warriors, Fujiwara Chikata, Kōga Saburō, the Hattori clan, and Heian-period bandits mastered Yamabushi Heihō, emerging as early inheritors of these techniques. Readers should pay particular attention to the frequent appearance of individuals from Iga and Kōga in these phenomena, as this highlights their significant role in the early development of ninjutsu.

Ninjutsu in the Genpei Period (1180-1185)

By the end of the Heian period (794–1185 CE), with signs of nationwide turmoil emerging, Yamabushi Heihō (Yamabushi Military Strategy) reached a stage of completion. This is exemplified by the Kurama Eight Styles (Kurama Hachiryū), a system in which military strategy (Heihō), martial arts (Bujutsu), and ninjutsu (Ninjutsu) were still grasped as a unified whole, not fully independent, but internally beginning to diverge into specialized fields.
Through the efforts of Minamoto no Yoshitsune and Ise Saburō Yoshimori, the first “ninjutsu manual” known as Yoshitsune-ryū Ninjutsu was written. While its contents are not yet fully separated from military strategy, the fact that ninjutsu emerged in a distinct, albeit incomplete, form from its foundation in the Kurama Eight Styles is noteworthy.
Another significant development of this era is the clear emergence of ninja clans in Iga. The fully developed form of Yamabushi Heihō was being passed down to the local warrior families (Jizamurai or Dogō, local chieftains) of Iga and Kōga. From this period onward, Yamabushi Heihō began to gradually transform into what would be recognized as “ninjutsu.”

Ninjutsu in the Kamakura Period (1185-1333)

During the Kamakura period (1185–1333 CE), the introduction of Zen Buddhism, which rapidly spread among the samurai class, had a significant impact on the later development of ninjutsu—a point worth noting.
In Iga and Kōga, the samurai groups that emerged internally, while operating in different environments, adopted a strict isolationist stance toward external forces. Internally, they began to advance their governance through a coalition of local chieftains (Dogō), employing a policy of direct military resistance against external enemies (through samurai unity) and a strategy of coexistence internally (balancing power among factions). It’s notable that the methods they adopted during the chaotic Sengoku period were already taking root at this time.
Additionally, two key developments influenced the later evolution of Iga and Kōga ninjutsu: the Iga ninja clan leaders, the Hattori (and Momochi) clans, reconciled with the newly arrived Ōe clan (from Kawachi), extending their influence into Yamato and Kawachi; and the Kōga ninja clans came under the control of the Sasaki clan, the provincial protectors, establishing a communication route to Kyoto (Kyōraku).

Ninjutsu in the Nanbokuchō Period (1336-1392)

During the late Kamakura period (1185–1333 CE), amidst the turmoil surrounding the fall of the Hōjō regime, a military genius, Kusunoki Masashige, rose to prominence. Masashige emerged as a master of unconventional tactics (Kihenpō), the foundation of ninjutsu, completing the framework for both offensive and defensive unconventional strategies that had been initiated by Minamoto no Yoshitsune during the Genpei period. Additionally, he established an independent organization for espionage and stratagem, advocating for the necessity of intelligence and covert operations during peacetime—what he termed Dakkōnin (political ninjutsu)—within the field of military science (Heigaku).
The ninjas of Iga and Kōga, alongside the Yamabushi, became a faction supporting the Southern Court through Masashige’s mediation.

Ninjutsu in the Sengoku Period (1467-1615)

The Sengoku period (1467–1615 CE) marks the era in which ninjutsu reached its full maturity.
It is only in this period that we can finally encounter “complete” ninjutsu.
During this time, “ninjutsu-like” practices emerged in various regions across the country, but apart from the ninjutsu of Iga and Kōga, no other form can be considered truly complete.
In this sense, Iga and Kōga ninjutsu represents the pinnacle of Japanese ninjutsu, far surpassing the hastily developed, naturally occurring ninjutsu of other regions in terms of sophistication. This is precisely why Iga (and Kōga) ninjas were so highly valued during this period.
It would not be an exaggeration to say that among the military commanders who best utilized ninjutsu, Tokugawa Ieyasu stands as the greatest and most significant. The influence of ninjutsu and ninja organizations in his rise to dominance cannot be overlooked.
Another notable fact is the significant impact that the introduction of gunpowder had on Iga (and Kōga) ninjutsu during this period.
Additionally, a key characteristic of this era is the emergence of distinct schools (Ryūha) in military science (Heigaku), martial arts (Bujutsu), and ninjutsu (Ninjutsu), with these disciplines developing a high degree of artisan-like specialization (Artisan-sei) while also becoming professionalized.

Ninjutsu During the Oda-Toyotomi Period (1568-1615)

The Oda-Toyotomi period (roughly 1568–1615 CE, spanning the reigns of Oda Nobunaga and Toyotomi Hideyoshi) was the era in which ninjutsu, perfected during the Sengoku period, flourished most vibrantly.
As mentioned previously, Japan’s largest and most formidable ninjutsu organizations—Iga-ryū and Kōga-ryū—were almost exclusively under the control of Tokugawa Ieyasu during this time.
Consequently, the history of ninjutsu in this period cannot be examined independently of Ieyasu’s policies and actions. The activities of ninjas during this era are directly tied to the establishment of the Tokugawa regime.
This section explores the adversarial relationship between Iga and Kōga ninjas and Oda Nobunaga and Toyotomi Hideyoshi, focusing on the events surrounding the Tenshō Iga Rebellion (1579–1581 CE), which was a major cause of this enmity. It also examines the movements of Iga and Kōga ninjas during this period, their nationwide dispersal, the origins and evolution of the Iga Dōshin (a ninja unit) within the Tokugawa Shogunate, and the history of the shogunate’s ninja management system within Iga.

Ninjutsu During the Tokugawa Period (1603-1868)

Overview of Ninjutsu’s Decline. Up until the early Tokugawa period, ninjutsu reached its peak, but as the demands of the era shifted, it rapidly entered a period of decline. The techniques and organizations of ninjutsu began to disintegrate swiftly, transitioning from political espionage to judicial espionage. It was during this time that ninjutsu’s secret manuals started to emerge publicly—a natural phenomenon given the changing times.
As the era of judicial espionage began, the rise of talented figures like Ōoka Echizen-no-Kami (Ōoka Tadasuke), who became the town magistrate, marked the entry of Kishū-ryū ninjas into the ranks of covert operatives.
The Shimabara Rebellion Chronicle (Shimabararanki) serves as a valuable record, casting a faint light on ninjutsu during its extinction phase alongside the last of the ninjas.

History of Ninjutsu: Seven Scabbard Cord Techniques

From 武神館兜龍 Bujinkan Toryu by Toryu

History of Ninjutsu: Seven Scabbard Cord Techniques

下緒七術 SHITAO SHICHIJUTSU (Seven Scabbard Cord Techniques) Page 201-204.

Seven Scabbard Cord Techniques. The scabbard cord (sageo) is a flat, woven strap attached to a protrusion called the chestnut shape (kurigata), located seven or eight sun (21–24 cm) from the scabbard’s mouth, on the outer side when the sword is worn. Typically, the sageo secures the scabbard to the waistband to prevent it from slipping, with a standard length of six shaku (about 1.8 m). However, ninja swords use longer cords, ranging from eight to twelve shaku (2.4–3.6 m), designed for versatile applications.

1. 座探しの術 ZAGASHI NO JUTSU (Technique of Searching While Seated)

As noted in the Art of Probing the Seat, the sageo is held taut in the mouth to keep the sword secure while probing in darkness, making it one of the seven sageo techniques.

    2. 止血・縛技の術 SHUKKETSU / SHIBARI-WAZA NO JUTSU (Technique for Hemostasis and Restraint)

    During combat, if the waistband or belt is cut, or when rising abruptly at night and unable to find the belt, use the sageo as a substitute. For wounds, cut the sageo to an appropriate length and tightly bind above the injury (closer to the heart for limbs) to temporarily stop bleeding. To restrain a captured enemy, use the eight-to-twelve-shaku sageo as a quick-binding rope.
    The “Finger-Lock Rope” or “Six-Inch Rope” method involves crossing the enemy’s hands behind their back, overlapping the fingers, and tying the thumbs’ joints in a cross pattern—six inches of cord suffice. A twelve-shaku sageo can bind six or seven enemies in a chain-like formation.

      3. 用心縄・通路仕掛の術 YŌJIN-NAWA / TSŪRO-JIKAKE NO JUTSU (Caution Rope / Corridor Trap Technique)

      As detailed later in the six articles on caution ropes, use the sageo as a low tripwire (set at knee height) stretched horizontally across a bedroom entrance. An enemy stepping in trips over the rope and falls, allowing the ninja, half-risen from the room’s center, to strike with a surprise slash (see illustratio

        4. 釣刀の法 TSURIGATANA NO HŌ (Sword-Hoisting Method)

        When scaling a wall, plant the ninja sword’s scabbard tip into the ground, using the sword and scabbard as a step. Place a foot on the guard to leap upward, grabbing the wall’s top. Hold one end of the sageo in the mouth while climbing, then pull the sword up by the sageo from atop the wall. This is called the Sword-Pulling Method.

          5. 幕張りの術 MAKUHARI NO JUTSU (Curtain-Pitching Technique)

          During wilderness camping, ninja tie four standing poles with sageo, drape oiled paper over them to form a tent, and shelter from rain, dew, or snow. For snow camping, gather dozens of fist-sized stones, arrange them in a layer, and build a fire atop them. After extinguishing the fire, lay dry grass on the warm stones, warm yourself with a dual-purpose matchlock tube (described later) tucked inside your clothing, and sleep.

            6. 旅枕の法 TABIMAKURA NO HŌ (Travel Pillow Method)

            For sleeping while traveling, tie the sageo of the long and short swords together, lay the taut sageo under your body, place the two swords upright, and lie atop them. The sageo runs horizontally under your back, with the long sword on the left and the short sword on the right, your body between them. Sleep hugging the long sword with your left arm.
            If a thief or enemy tries to steal the swords during deep sleep, the sageo’s movement under your back wakes you. Instantly, while still lying, fling the scabbard toward your feet, draw the blade toward your head, and thrust at the enemy. Ninja draw their swords by throwing the scabbard in the opposite direction, halving the time needed to unsheathe compared to standard methods.
            When pursuing an enemy or fleeing in haste without time to retie the waistband, tie the swords’ sageo together, loop it around your neck, let the swords dangle in front, and run while retying the waistband to secure them at the waist.

              7. 鑓止めの術 YARIU-DOME NO JUTSU (Spear-Stopping Technique)

              This sword technique immobilizes an enemy wielding a long weapon like a spear or long sword, rendering it useless, and allows a thrusting strike. Draw the ninja sword with its scabbard from the waist, quickly tie one end of the sageo to the hilt, and unsheathe the blade, holding it in the left hand with the scabbard’s mouth facing you. Extend the scabbard in the right hand toward the enemy at eye level, raise the blade in the left hand to an upper stance, with the sageo taut vertically along your right side. Wait calmly in this stance.
              If the enemy’s spear thrusts low toward your abdomen, cross the blade and scabbard to catch it, press it to the ground, kick the shaft to pin it, and thrust the blade to fell the enemy. If aimed high at your face, cross the blade and scabbard upward to parry the shaft, ready the blade forward, and thrust to kill.
              If the spear aims at your chest and passes to the right of the sageo, step slightly left-diagonal forward, parry the spear tip rightward, raise your right elbow to clamp the shaft under your right arm, swiftly swap the blade and scabbard between hands, and open your arms to wrap the sageo around the shaft, binding it. Restrict the spear’s thrusting or pulling, step in at the right moment, and thrust the flat blade into the enemy’s chest to kill. If the spear passes to the sageo’s left, step right-diagonal forward, parry the spear leftward, clamp the shaft under your left armpit, swap blade and scabbard, wrap the sageo around the shaft to immobilize it, and thrust as before to kill.

                These are the Seven Scabbard Cord Techniques, fully utilizing the sageo’s potential.

                History of Ninjutsu: Ninja Running Techniques

                From 武神館兜龍 Bujinkan Toryu by Toryu

                History of Ninjutsu: Ninja Running Techniques

                Ninja Running Techniques, the importance of running for ninja is evident from the escape story of Nikuruma Inosuke, as mentioned earlier. Terms like “swift-footed” or “fast-footed group” are entirely fitting for ninja.

                横走り Yoko-bashiri (Side Running)

                A distinctive ninja running technique is side running. With their back against a wall, holding a sword facing forward toward an enemy, ninja run sideways. This method is ideal for navigating narrow spaces, such as those only chest-width wide.
                The legs cross deeply in a zigzag pattern, then spread wide to the right or left in a large X-shape, repeating to move sideways, either running or hopping. In side running, even cutting through the wind, the mouth avoids air resistance, and there’s no worry of dust entering the eyes. One can eat, shout to communicate with allies, or even urinate while running. Once mastered, side running is said to be far more convenient than normal running.

                斜め走り Naname-bashiri (Diagonal Running)

                When ascending steep slopes, running straight up is less efficient than running diagonally. Zigzagging by running diagonally right, then diagonally left, is easier and helps evade enemy gunfire or arrows. Slightly lowering the face during diagonal running reduces air resistance at the mouth. Arm movement is crucial: crossing both arms broadly in front of the chest and swinging them wide imparts momentum, propelling the legs diagonally as if leaping, increasing speed and reducing fatigue.

                後ろ走り Ushiro-bashiro (Backward Running)

                While backward walking is possible, backward running is slow, and the terrain ahead is hard to see, making it frightening and impractical. I believe backward running is a ninja trick.
                Experiments in dim light show most people fail to notice this ruse, supporting my hypothesis. Backward running is used when pursued and at risk of being cut down from behind. The ninja turns to face the approaching enemy, holding the sword in a seigan (eye-level) stance or spewing fire and smoke from the mouth, then flees backward at high speed while maintaining this posture (see frontispiece illustration).
                During infiltration, ninja carry a demon or tengu mask preloaded with fireworks in their chest. When pursued closely, they ignite the firework’s fuse, place the mask on the back of their head, and, while holding the sword backward, run forward. To the enemy, it appears the ninja is retreating backward while facing them with a sword. As noted in the attire section, sandals must have heel-stop fittings.

                暗闇を疾走する法 Kurayami o Shissō suru Hō (The Method of Running Swiftly Through Darkness)

                The infamous “Sermon Bandit” from Taisho-era crime history, who broke into homes, assaulted women, stole valuables, and stayed from midnight to dawn, offers a relevant example. He preached to households, advising them to brighten the outside and darken the inside for safety or to keep dogs, biding time until just before the first train, then fleeing at high speed through the dark, breaking through police cordons before they tightened, escaping beyond their reach. His knack for sprinting through darkness kept him elusive. This ninja-like figure, Tsumaki Matsukichi, claimed to be from the mountains.

                When captured and asked how he ran through darkness, Tsumaki Matsukichi’s response mirrored ninja techniques, prompting me to ponder the connection between mountain life and ninjutsu. He explained: Holding a bamboo sword or long bamboo staff straight ahead horizontally, he lowered his face (since the dark obscured vision) and ran. When hitting a wall or obstacle, he bent his arm to absorb the impact, changed direction, and continued running in the same posture. The bamboo acted as an antenna.

                Ninja used the same principle to sprint through dark paths, but instead of a bamboo sword or staff, they employed the Zasaguri no Jutsu (probing technique) from the seven sageo arts. Holding the sword and scabbard horizontally forward, with the sageo’s end in their mouth to suspend the sword, they lowered their face and ran. When the scabbard’s tip hit an obstacle, it snapped back onto the blade, cushioning the impact as the scabbard slid. Ninja swords had sturdy iron kojiri (end caps), a reinforcing band, a ring-shaped kurigata (cord loop), and a robust koguchi (scabbard mouth) fitting, making scabbard damage highly unlikely.

                History of Ninjutsu: Ninja Jumping Techniques

                From 武神館兜龍 Bujinkan Toryu by Toryu

                History of Ninjutsu: Ninja Jumping Techniques

                Ninja Jumping often need to escape by leaping over obstacles or walls, grabbing onto house eaves, or dodging sideways in the blink of an eye to hide from enemies. They may also have to jump across rivers too wide for pursuers or leap from low to high places to evade capture. When infiltrating enemy castles or houses, the ability to fly like a bird would render defenses and ambushes nearly irrelevant.

                Ninja techniques include the Six Jumping Methods, encompassing six types of jumps:

                1. Forward Jump (Mae-tobi)
                2. Backward Jump (Ushiro-tobi)
                3. High Jump (Taka-tobi)
                4. Long Jump (Haba-tobi)
                5. Side Jump (Yoko-tobi)
                6. Diagonal Jump (Naname-tobi)

                The standards are a high jump of 9 shaku (2.7 m), a long jump of 18 shaku (5.4 m), and a downward jump of 50 shaku (15 m). These figures likely represent ideal targets for ninja training. Beyond these, jumps were performed in pairs or trios or with tools.

                忍びの跳躍訓練 Shinobi no Chōyaku Kunren (Ninja Jump Training)

                To leap effectively, one must be light. Ninja regularly used slimming medicines made from wild coix seeds, ate tofu as a staple to maintain nutrition without gaining fat, and underwent rigorous, balanced daily training. This reduced excess fat, tightened muscles, and developed a flexible, resilient, steel-like physique.

                During intense physical training, ninja reportedly wore deer leather undergarments. Sweating from vigorous movement wetted the leather, causing it to cling and constrict the body. Enduring this discomfort during training gradually slimmed the body and reduced sweating, as body odor could betray a ninja’s presence.

                Jump training involved sowing hemp seeds in a plot of land and waiting for germination. Hemp grows rapidly, stretching taller daily. Ninja practiced jumping over it—forward, backward, sideways, and diagonally. Initially easy, the task grew harder as the hemp grew. Such training for about three years was necessary to become a competent ninja.

                二人組人馬興業停止令 Futarigumi Jinba Kōgyō Teishi Rei (Two-Person Horseback Technique)

                The term “ninba” (human horse) refers to a mid-Edo period spectacle, akin to modern circus acts, but I believe it originated as a ninja technique for leaping over high walls. Historical records claim it was devised in the Genroku era (1688–1704) for performances, but I suspect it’s older.

                In Kyoto, a performer named Numa from Kinbuya Tabee, during the Genroku era, went to Edo, joined the equestrian Sasaki Heima’s school, and allegedly created the ninba technique inspired by equestrian skills. However, equestrianism and ninba share no technical similarities.

                The Rakushu Genbun Taiheiki, Volume 4, mentions Sasaki Heima’s fame and ninba’s ability to astonish audiences. On July 24, Genbun 5 (1740), ninba performances were banned again. Though presented as derived from equestrianism, I believe destitute ninja, no longer receiving stipends, used their trained ninba skills in performances. Records show ninba was banned three times.

                The Seihōroku, in an entry for April, Hōei 4 (1707), notes: “Recently, various acrobatics called ninba have gathered crowds, leading to imitators and potential misconduct, so ninba and other acrobatic performances are henceforth prohibited.” Another ban was issued in Genbun 5 (1740), and on May 11, Kanpō 2 (1742), the Asakusa-ji Diary records the dismantling of an acrobatics booth at Asakusa Temple due to concerns that “undesirable people learning and using it could lead to trouble.” The bans were issued because ninba could be misused by thieves if publicly displayed.

                Was ninba such a shocking technique to warrant such scrutiny?

                二人組人馬の技法 Futarigumi Jinba no Gihō (Two-Person Ninba Technique)

                Jumping over a 10-meter-high wall or obstacle without tools is difficult, but with the two-person ninba technique, ninja could soar like birds (see frontispiece illustration).

                One person stands with another on their shoulders, facing a high wall. For stability, the upper person places their feet on the lower’s shoulders, firmly grips the lower’s head, and crouches to avoid falling, timing the takeoff. The lower person holds the upper’s legs for stability. Both synchronize their breathing, sprint toward the wall or obstacle at tremendous speed, and at the optimal distance, the upper person kicks off the shoulders to leap, while the lower throws the upper’s legs upward. With the momentum of the sprint and elastic body movement, the black shadow arcs through the air like a projectile, clearing the obstacle.

                For house infiltration, once one ninja lands inside, they throw a climbing rope outside, easily pulling the other over the wall (see illustration).

                三人組人馬の技法 Sanningumi Jinba no Gihō (Three-Person Ninba Technique)

                For obstacles over 10 meters that a two-person ninba cannot clear, a three-person technique is used. One person sits on a stone 4–5 meters from the obstacle, facing away, knees aligned horizontally. A second person stands naturally on the seated person’s back. The jumper starts a sprint from as far as 10 meters away, steps onto the seated person’s knees as a launch platform, and leaps upward. Just before, the seated person supports the jumper’s soles or thighs, and the standing person grips the jumper’s torso, all synchronizing to hurl the jumper high over the obstacle (see frontispiece illustration).

                These flight techniques are most dangerous during landing, and until mastered, they reportedly cause frequent fractures, sprains, and bruises. I once saw the Soviet Russian Ballet perform a Cossack dance where dancers leaped high from the stage’s back, soaring over others to land at the front, using a method nearly identical to the three-person ninba. This technique likely originated in mainland China, spread north to the Cossacks, and eastward to Japan with ninjutsu. The claim it was devised from equestrianism in the Genroku era is likely a ninja cover story or jest.

                Hop, Step, Jump

                With a four-person team, jumping onto a 3–4-meter wall is simpler. One person leans against the wall, hands on it, head lowered, standing naturally. A second person firmly grasps the first’s waist, braces their feet, tilts their head right or left, and flattens their back. A third person hugs the second’s legs, crouches low, and flattens their back. The jumper sprints, using a triple-jump approach, stepping on the first, second, and third person’s backs, then leaping from the third to grab the wall’s edge (see frontispiece illustration).

                Tool-Assisted Methods

                Using a sturdy long board and a stone, create a seesaw. The jumper stands on one end, and another person jumps from their shoulders onto the raised end, launching the jumper over the wall. Pole vaulting with a spear or pole, or swinging across with a climbing rope like a pendulum, were also used.

                History of Ninjutsu: Evolution of Ninja Terms

                From 武神館兜龍 Bujinkan Toryu by Toryu

                History of Ninjutsu: Evolution of Ninja Terms

                Ninjutsu history begins with terms like 忍者 Ninja and 忍法 Ninpō, the most commonly accepted in modern times, which are newly coined words from the 昭和 Shōwa era (1926–1989). The term 忍術使い Ninjutsu Tsukai (Ninjutsu user) is a newly coined word from the 明治 Meiji (1868–1912) and 大正 Taishō (1912–1926) eras. In the 江戸 Edo period (1603–1868), the representative terms were 忍び Shinobi or 忍びの者 Shinobi no Mono (Shinobi person), and the techniques were called 忍術 Ninjutsu.

                Using the term お庭番 Oniwaban (garden guard) in the same way as Shinobi no Mono is a mistake. Oniwaban is a job title in the shogunate, but since Shinobi were assigned to this role, the shogunate’s covert agents were called Oniwaban. However, it is strange for television or movies to feature Shinobi as the Oniwaban of the 上杉家 Uesugi family or the 伊達家 Date family. The names for Shinobi varied across different domains and regions.

                In general, even in China, the homeland, the names for Shinobi varied across different regions with various designations.

                • 遊子 Yūshi (In 大橋 Ōhashi, Shinobi are called Yūshi. Does this mean one who travels between enemy and ally, or one who takes the form of a playful figure?)
                • 行人 Kōjin (In 陰経 Inkyō, Shinobi are called Kōjin. Like Yūshi, it likely means a person who goes back and forth between enemy and ally.)
                • 遁形 Tongyō (In 五雑爼 Gozassho, they are called Tongyō. Shinobi are not combatants; their essence is to gather information and escape, meaning a person who masters the form of passing through.)
                • 間 Kan (In the state of 具 Chu, they were called Kan. The meaning of Kan is as previously described, and from this, Japan created the term 間者 Kanja [spy].)
                • 課 Saku (In the 春秋 Spring and Autumn period, they were exclusively called Saku. The literal meaning of Saku includes “to spy.” It refers to the role of spying on and probing the enemy’s situation.)
                • 遊偵 Yūtei, 細作 Saisaku, 姦細 Kansei, 好細 Kōsei (After the Warring States period, in China, Shinobi were called Yūtei, Saisaku, Kansei, Kōsei, etc. This likely means traveling between enemy and ally in a playful form to spy on the enemy’s situation, probing the enemy’s situation in detail and reporting to the general, who then uses this to devise detailed strategies. Additionally, calling Shinobi 森細 Seisai or 妊細 Ninsei likely means a job that appears ordinary on the surface but involves deep, cunning schemes behind the scenes.)

                In ancient China, they were called as above, but after being introduced to Japan, from the Muromachi period (1336–1573) to the early Warring States period, they were called:

                • 草 Kusa (Grass)
                • かまり Kamari (Spy)
                • 水彼 Suppa (Water Other)
                • 乱破 Rappa (Chaos Breaker)
                • 突破 Toppa (Break Through)
                • 出抜 Denuki (Exit Pull)
                • うかみ処 Ukami Dokoro (Spy Place)

                武田玄 Takeda Shingen called Shinobi the 三つの者 Mittsu no Mono (Three Types of People). He divided them into three roles, and collectively referred to them as the 三つの者 Mittsu no Mono (Three Types of People).

                … and so on.

                1. —間見 Kanmi (observer),
                2. 見分 Mikewake (inspector), and
                3. 目付 Metsuke (overseer)

                上杉謙倍 Uesugi Kenshin called Shinobi 猿 Nokizaru (roof monkeys).

                織田長 Oda Nobunaga called Shinobi 製談 Kyōdan (conversers).

                In the Tokugawa period, Shinobi themselves used the characters 獺盗 kawai nui (otter thief) to read as Shinobi, or, seemingly disliking the sound of the word Shinobi, they tried to avoid using the character 忍び Shinobi as much as possible. They used terms like:

                • 早道の者 Hayamichi no Mono (fast path person)
                • 早足組 Hayaashigumi (fast-footed group)
                • 忍び目付 Shinobi Metsuke (Shinobi overseer)
                • 物聞き Monokiki (listener)
                • 黒はばき Kurohabaki (black leg guards)
                • 小隼人組 Kohayato Gumi (津軽藩 Tsugaru Domain, a Shinobi group led by 中川小隼人 Nakagawa Kohayato, a 200-koku retainer)
                • 鳥組 Tori Gumi (Sendai Domain, a guerrilla unit led by Shinobi 細谷十大夫 Hosoya Jūdayū)

                These names make it hard to think of them as groups of Shinobi. Even in modern times, people from Shinobi lineages strongly dislike announcing that their family has Shinobi blood.

                If a Shinobi is known to be a Shinobi, they can no longer fulfill their role. In other words, they become useless, and simply being a Shinobi led to discriminatory treatment by ordinary samurai, being shunned, and even having marriage proposals rejected—a dark past they carry. Why this happened will be explained later, but the essence of a Shinobi is inherently such, a matter of fate, and nothing can be done about it.

                Ninjutsu and Shugendo: A Shared Mystical Legacy

                From 武神館兜龍 Bujinkan Toryu by Toryu

                Ninjutsu and Shugendo: A Shared Mystical Legacy

                Ninjutsu and Shugendo are two enigmatic Japanese traditions that blend martial skill with spiritual mysticism. Their roots trace back to the fall of 百済 Baekje in 663 AD, when refugees, including 姚玉虎 Chō Gyokko (Yao Yuhu), fled to Japan. Chō Gyokko, a historical figure, brought martial techniques and Taoist practices from 唐 Tō (Tang China), influencing early Ninjutsu schools like 玉虎流 Gyokko-ryu and 虎倒流 Koto-ryu. Around the same era, 役行者 En no Gyōja (En the Ascetic) established 修験道 Shugendo, a path of mountain asceticism. This article explores their shared origins and practices, featuring direct insights from 山田雄司 Yamada Yuji (Professor Yuji Yamada) and 長谷川智 Hasegawa Satoshi (Yamabushi Satoshi Hasegawa) in their original Japanese kanji.

                The Baekje Influence on Ninjutsu and Shugendo

                The collapse of Baekje spurred a wave of cultural exchange as exiles introduced combat skills and spiritual traditions to Japan. Figures like Chō Gyokko played a pivotal role in shaping Ninjutsu’s foundations. Meanwhile, Shugendo emerged as a unique spiritual discipline. Professor Yamada highlights a critical link between the two:

                「九字護身法は元々中国の道教のもので、それが修験道で入山する時に自分の身を霊的に守護するための作法になりました。忍者も印を結んだり九字を切ったりしますが、これらは修験道由来です」
                (Translation: “The nine-syllable kuji-in came from Chinese Taoist practices, adopted by Shugendo to spiritually protect oneself in the mountains, and later passed to Ninjutsu”).

                This statement underscores how Baekje’s legacy influenced both traditions through shared esoteric practices.

                Shared Practices: Kuji-in and Mountain Training

                The 九字印 kuji-in hand seals represent a profound connection between Ninjutsu and Shugendo. In Ninjutsu, these gestures served both practical and mystical roles. Yamada explains:

                「忍者が印を結ぶのは、命がけの任務に臨む際に神仏の加護を得て、自身のメンタルを安定させるという実用的な面も大きかった」
                (Translation: “Ninjas used kuji-in to gain divine protection and mental stability before life-or-death missions”).

                In Shugendo, the seals carried a deeper spiritual weight. Hasegawa elaborates:

                「修験道は密教の影響が強いので、密教で重視される「三密(身・ロ・意)」の「身=身体」で、ある種の形を作ることで精神的な影響を起します」
                (Translation: “In Shugendo, influenced by esoteric Buddhism, the ‘three secrets’—body, speech, mind—are used, with the body forming seals to create spiritual effects”).

                Mountains also played a central role in both disciplines. Yamada notes:

                「忍者は山中で修行を積んで、肉体的な鍛錬と同時に「何があっても大丈夫だ」という精神性を身に付ける」
                (Translation: “Ninjas trained in mountains to build endurance and a resilient mindset”).

                Hasegawa complements this:

                「山を歩くのは感性を磨くのに重要で、どんな此細な変化も見過ごさずに察する」
                (Translation: “Walking in mountains sharpens the senses, teaching one to notice subtle changes”).

                These quotes reveal how kuji-in and mountain training bridged the martial and mystical aspects of Ninjutsu and Shugendo.

                A Lasting Connection

                The contributions of Baekje exiles like Chō Gyokko shaped Ninjutsu, while En no Gyōja forged Shugendo’s path. Despite their differences, both traditions share rituals like kuji-in and a reverence for mountain training, as evidenced by the exact words of Yamada and Hasegawa. This fusion of martial and mystical elements highlights their intertwined heritage.
