Ninja Juhakkei 忍者十八形

Ninja Jūhakkei (the eighteen disciplines; 忍者十八形) were first identified in the scrolls of Togakure-ryū 戸隠流, or “School of the Hidden Door”, founded during the Oho period (1161–62) by one Daisuke Nishina (Togakure), who learned a life view and techniques (ninjutsu) from Kagakure Doshi[1]. Togakure ryu Ninjutsu Hidensho[2] is a manuscript in Hatsumi’s possession that is said to document Togakure-ryū. It is the purported origin of the “18 skills of Ninjutsu.”

Ninja jūhakkei was often studied along with Bugei jūhappan (the 18 samurai fighting art skills). Though some techniques were used in the same way by both samurai and ninja, others were used differently by the two groups. The 18 disciplines are:

  1. Seishinteki kyōyō (spiritual refinement)
  2. Koppojutsu Tajutsu (unarmed combat)
  3. Kenpo (Swordsmanship)
  4. Bōjutsu (longstaff)
  5. Shuriken (throwing blades)
  6. Kusarigama (chain and sickle
  7. Yari (spear)
  8. Naginata (halbred)
  9. Bajutsu (horsemanship)
  10. Suiren (water training)
  11. Kayakujutsu (pyrotechnics)
  12. Hōryaku (tactics)
  13. Chōhō (espionage)
  14. Shinobi-iri (Infiltration)
  15. Inton (Concealment)
  16. Hensōjutsu (disguise)
  17. Tenmon (meteorology)
  18. Chi-mon (geography)

[2] Here, “hidensho” simply refers to the secret manuscripts of Togakure-ninjutsu. In this particular case, it is referring to Buhi Kanjin Kanami no Maki (武秘神眼要巻). This particular scroll serves as a sort of mokuroku for the Togakure-ryu, and has been made publicly available in Masaaki Hatsumi’s publication “The Complete Ninja: The Secret World Revealed” (2013, p. 98-99).
