Ryōi Shintō-ryū (良移心頭流) was introduced in the Shōtoku era (正徳年間) by Mori Hachiroemon (森八郎右衛門), a Chikujin ronin, who was invited by the Kurume domain (久留米藩) as a Jūjutsu instructor (柔術師範) to teach jujutsu.

It flourished from the end of the Edo period to the middle of the Meiji period, and in 1883, Nakamura Hansuke (中村半助), a vassal of Chikugo Arii (筑後有飯), was invited to be the first Jūjutsu instructor (柔術指南役) to the Tokyo Metropolitan Police Department (東京警視 庁)

The latter (Nakamura ) was famous in the world of this art for its matches in the Metropolitan Police Department, which are said to be a showdown between Jūjutsu and Jūdō), and Uehara Shōgo (上原庄吾) are from the mainstream style (of Ryōi Shintō-ryū)."
