Koto Ryu

KOTO Ryu (虎倒流 Kotōryū) is a school of koppojutsu(骨法術) , "shurikenjutsu", and "kenjutsu". This school specializes in using larger bones to strike weaker ones of your opponent.

The tradition of Koto Ryu koppojutsu began with Toda Sakyo Isshinsai during the Tenmon Era (1532 - 1550) after learning Gyokko Ryu shitojutsu from Sakagami Taro Kunishige. It is a sister art of "Gyokko Ryu" kosshijutsu (玉虎流骨指術). Toda taught both of these arts to Momochi Sandayu and they were handed down within Iga Ryu until reaching Toda Shinryuken Masamitsu in the late Tokugawa period. The foundation of "Togakure Ryu" ninpo comes from the unarmed combative movements of Koto Ryu and Gyokko Ryu.

It can be translated as "Knocking down the Tiger" School, which is an image shared with its sister school, Gyokko Ryu (also can be translated as "Jeweled Tiger School"). In addition Koto Ryu includes a 4 pointed "Hira Shuriken" or "Shaken" along with blade fighting.

This school is taught inside the "Bujinkan", "Genbukan", "Jinenkan" , and under "Tanaka Fumon"
