Togakure Ryu (戸隠流忍法体術)
Was founded by Diasuke Nishina who was raised as a vassal of Kiso Yoshinaka in the early 12th century. When Yoshinaka’s army was defeated in battle, Diasuke escaped to Iga. There he learned various martial skills such as kosshijutsu and kenjutsu from Kagakure Doshi. It was initially called Togakure Ryu Happo Biken but has been called by various names since that time. Togakure Ryu is known for its use of tekko, senban nage and shinodake (4-foot breathing tube).

Gyokko Ryu (玉虎流骨指術)
It is believed that a Chinese person named Ikai introduced this art to Japan in the 8th century. According to Hatsumi Sensei, that person could also be somebody (kai) from a foreign (i) country. It is assumed that this kosshijutsu was based on Chinese martial arts. Although kosshijutsu means “to be able to knock down an enemy with one finger”, it can also signify the “backbone” [spine] of the martial arts.

Kukishinden Ryu (九鬼神伝流八法秘剣術)
The founder of this tradition was Yakushimaru Kurando Takazane, a palace guard of Emperor Godaigo in the 1330’s. He was awarded the family name of Kuki (nine demons) for his spirited fighting and rescue of the Emperor. In addition to bo, yari, shuriken and unarmed fighting methods, this tradition is well known for its bojutsu and kenjutsu. Due in part to the Kuki family’s activities as suigun (navy) they adapted a low fighting posture that permitted better balance on turbulent waters. This tradition is related to Kukishin Ryu which is well known for its bojutsu.

Shinden Fudo Ryu (神伝不動流打拳体術)
This ryu was founded by Izumo Kanja Yoshiteru. A characteristic of this ryu is its recognition of shizen (“natural”) as the only necessary posture of defense. However, in reality, a person imagines a posture of defense in his mind and places himself on guard. This tradition has two sections of fighting (dakentaijutsu & jutaijutsu) as well as the philosophy of not drawing a sword unless absolutely necessary.

Koto Ryu (虎倒流骨法術)
This art was founded in the middle of the 16th century by Toda Sankyo Ishinsai who had learned Gyokko Ryu from Gyokkan, a Buddhist monk. Koppojutsu originally came from ancient China and was also called Goho, which was characterized by its use of hidden weapons. The first kanji of koppo (kotsu) means bone, but can have the deeper meaning of “knack”.

Gikan Ryu (義鑑流骨法術)
Founded by Unryu Hangan Gikanbo, Daimyo of Kawachi Province. He developed this art from his lessons in kosshijutsu. The lessons of this tradition are almost totally unknown to the public and many of its secret techniques were handed down from soke to soke only.

Takagi Yoshin Ryu (高木揚心流柔体術)
Traces its lineage back to the 16th century scroll Rinpo Hiden which was studied by Ito Ki-i no Kami. This tradition was founded by Takagi Oriemon Shigenobu. This art developed through the years and has strong links to Takeuchi Ryu, Kukishin Ryu and Hontai Yoshin Ryu. This tradition teaches to always remain calm and flexible like the willow.

Gyokushin Ryu (玉心流忍法)
This art is a branch of kosshijutsu and was founded by Sasaki Goemon Teruyoshi. Characteristics of this tradition include its unique usage of nawa nage (rope throwing) and espionage techniques. The secrets of this tradition have only been hinted about by the current grandmaster.

Kumogakure Ryu (雲隠流忍法)
This martial art was founded by Heinaizaemon Ienaga Iga (Kumogakure Hoshi) who was also believed to be the originator of Iga Ryu Ninjutsu. The special skills of this tradition include its use of the kamayari (sickle spear) and kote uchi (forearm striking) techniques. Much of the training in this tradition is said to be likened to the taijutsu and philosophies of escape and evasion techniques in Togakure Ryu.
