Shinohara Yasunobu 篠原泰之進 (1828 - 1911) trained in Ryōi Shintō-ryū Jūjutsu (良移心當流 柔術) in the Shimosaka Dojo in Kurume under Shimosaka Gorobei (下坂五郎兵 - aka Shimosaka Yosō Tayū Shigenobu 下坂与三 太夫 重信).

Shinohara was a member of the famous ‘Shinsengumi’(新選組 - New Selected Group), a special police / militia unit sent up by the Bakufu 幕府 (Tokugawa 徳川) government in 1864. They had a fearsome and often brutal reputation for suppressing rebellious factions in and around the Imperial Capital of Kyōto (京都). With the Meiji restoration (明治維新) in 1868, they found themselves on the wrong side of history, but Shinohara had already left them by then.

On page 142 of his book ‘Shinsengumi – The Shogun’s Last Samurai Corps’ Romulus Hillsborough (2005) describes how in (approx.) May 1867: “The instructors taught kenjutsu, jūjutsu, yarijutsu, horsemanship, artillery, and literature. Among the kenjutsu instructors were Okita, Nagakura, and Saitō. Tani Sanjurō taught yarijutsu. Shinohara taught jujutsu. Itō and Takeda taught literature.”

This provides good evidence that Ryōi Shintō-ryū was the Jūjutsu of the famous ‘Shinsengumi’.

He was later employed in the Magistrates office in Yokohama and towards the end of the Edo period became a member of the Shinsengumi (新選組 Shogunate Special Police) and fought with the Satsuma in the Battle of Toba-Fushimi (鳥羽・伏見). He was involved in an assassination attempt on Kondō Isami (近藤 勇).

Post the Meiji Restoration (1868), he conducted inspections for the Ministry of Finance, became a businessman (although apparently he wasn't particularly successful) and later, became a devout Christian. He died in Aoyama, Tokyo at the age of 84 and his grave is in the Aoyama cemetery.https://en.wikipedia.org/wiki/Shinsengumi
