Shiro Saigo and Yama Arashi

Shiro Saigo was an early follower of Jigoro Kano, soon after he founded the Kodokan. Many competitions were held between the Kodokan and older, established schools of Jujutsu. Saigo's victories was partly responsible for the ensuing popularity of Judo as a result.

He is said to have invented the "unstoppable" Yama Arashi throw. 

Akira Kurosawa based the film Sanshiro Sugata on the life and career of Saigo. 

Below is a short documentary on Saigo.
