Kito - Ryu. An ancient school of Ju-Jutsu which developed from the 17th to the18th century. Its five priciple Kata have been preserved in the Koshiki-no- Kata of Kodokan Judo. The teachings of this school are to be found in two ancient texts, Hontai and Seiko, transmitted by the Buddhist priest Takuan. He tried to transform the combat techniques of Ju-Jutsu into an art and system of aesthetic behaviour. Kito - Ryu was founded at the end of the sixteenth century bt a Samurai of low rank, Ibaragi Sensai, a product of the Yagyu Shinkage Ryu. Kito-Ryu taught Ken -Jutsu, Bo-jusu, Iai-Jutsu and other weapon techniques, such as those of the Kusari-Gama. Later, this school gave birth to numerous others, such as Teishin-Ryu , founded by Terama Heizaemon, and Fukuno Shichiroemon. But it was thanks to Terada Kanemon that Kito-Ryu developed into a specific art of combat using only thr bare hands, which he called Judo; he created his own school , Jikishin-Ryu.(A Dictionary of the Martial Arts, Frederic)
