This was a leading school of Ju-jutsu in the late Edo and Meiji eras; it influenced schools of Jujutsu such as Tenjin Shinyo Ryu and eventually Kodokan Judo. The founder is Yamamoto ‘Minzaemon’ Hidehaya (1715 - 1798) a resident of Osaka and a “doshin” (同心) for Osaka castle. He studied Yoshin Ryu under Goemon Motoyoshi and received a teaching license, but wasn't satisfied with the school and felt he could improve it. The story goes he chose from among 303 “te” (“hand”- possibly techniques) from “tegata” (“printed bills”- possibly complete techniques). He added his own methods and then aggregated them into 87 complete techniques, dividing the school up into four levels: first, middle, upper, and inner. In 1751 (Horeki 1) he called his school “Shin no Shinto Ryu”. Eventually he was relocated to the city of Edo (Tokyo), opened his school there and made a name for himself. The second generation inheritor is believed to be Dohi ‘Mugensai’ Yasanobu who gained fame as a master of alleged “killing” techniques. The third generation is said to be Takeemon Honma, (also called Fubuki Santoku) who studied the sword under Kushibuchi Nobumoto, the founder of Shindo Isshin-ryu. Iso Mataemon, who founded Tenjin Shinyo-ryu, was originally one of Honma’s students. It is also said that under the first generation or second generation of teachers, there was interaction with Kito-ryu under Hatta Yoriyasu and Takino Yuken, who were teaching and spreading the school around Osaka at that time. It appears that many of the Kito-ryu methods and techniques were incorporated into the school directly and vice versa, moreover counter techniques to Yoshin Ryu appear. According to one theory, Hatta Yoriyasu was studying the Shin no Shinto Ryu under Yamamoto Hidehaya before he started his own school. The school became popular and spread nationwide, and it is believed that was due to three generations of the school actively teaching all at the same time. It also appears that the school was teaching Judo in their dojo as an introduction, and Shin No Shinto Ryu was taught as core techniques during the Meiji, Taisho, and up to the beginning of the Showa era. However, during the Second World War the ‘lineage’ licensed teachers started to die or became inactive, the small groups they left behind disappeared, and the school may have gone extinct.
