Ryōi Shintō-ryū Jūjutsu 良移心当流 [ja] 柔術, (also known as Fukuno-ryū 福野流, Shintō Yawara 神当和, or Ryōi Shintō-ryū Yawara 良移心當流和[1]) is a traditional school (Koryū 古流, old style) of Jujutsu (柔術), founded in the early 17th century by Fukuno Shichirouemon Masakatsu (福野七郎右衛門正勝).
The 'Ryōi Shintō-ryū Denju Mokuroko' (良移心当流 伝授 目録) explains the meaning of Ryōi Shintō as follows: "The meaning of Ryōi Shintō-ryū is to shift (i 移) your heart (shin 心) well (ryō 良), then you will encounter (tō 当) harmony (wa 和, or yawara, an alternative tern for jujutsu).
"[2] Alternatively, the 'Ryōi Shintō-ryū Ryakushi' records Fukuno as saying that: "Ryōi Shintō means to: skillfully apply the mind (shin 心) and strike (tō 当) with ease.
[5] Also, through its Kitō-ryū roots, Kōdōkan Jūdō (講道館 柔道) can be seen as being partially descended from Ryōi Shintō-ryū Jūjutsu.
Fukuno endured mental tortures and developed his physique, and after twenty years or so, he finally acquired mastery of Nomi no Sukune's techniques.
Later, in the ‘Meiji period’ (1868–1912), Ryōi Shintō-ryū Jūjutsuka – Hansuke Nakamura (中村半助) was considered the toughest martial artist in Japan.
