山嵐, Yama Arashi
Yama Arashi (山嵐, Yama Arashi, literally: "Mountain Storm") is the mortal technique of Shiro Saigo, an incomparable judo genius that inspired Sanshiro Sugata.
It is one of the preserved throwing techniques, Habukareta Waza, of Judo. It belonged to the fifth group, Dai Gokyo, of the 1895 Gokyo no Waza lists. It is categorized as a hand throwing technique, Te-waza.
In the history of judo, it is both the most beautiful yet most dangerous throw of all. Using the destructive power of a catapult it almost looks like a thigh sweeping throw. Since it is categorized as a hand technique, the technique must have been thought of being primarily executed by tori's arms. It was said that after saigo’s disappearance, this legendary technique never found someone able to use it.
