Yoshio Sugino

He first encountered martial arts at Keio University, where he enrolled in 1918; here he joined the judo, kendo, sumo and kyūdō clubs, among others.

[3] Jigoro Kano, the founder of judo, introduced Sugino to the Katori Shinto-ryu school of kenjutsu in 1927.

Sugino and his family fled to Fukushima, where he spent most of his time in martial arts training and used his medical knowledge (he had run a bone-setting clinic from his dojo in Kawasaki) to help the injured.

[3] In 1953, Sugino was asked to provide sword instruction for the actors in Akira Kurosawa's film, Seven Samurai.

His choreography for the fights departed from earlier, Kabuki-influenced work and focused on making the scenes as realistic as possible.
