Sochin
Sochin (tranquil force)
aka: Hakko (strongly rooted)
This kata features the stance sochin dachi, more commonly known as fudo dachi - the immoveable stance. It is strong and solid, and a great kata to practice in order to develop a powerful base from which to launch explosive attacks.
History
Sochin was most likely created or adapted in the 1930s by Yoshitaka Funakoshi, perhaps taking the earlier Aragaki Sochin as a model (which is Chinese in origin and features neko-ashi dachi) and forging his distinctive style onto it. Gichin Funakoshi used the name Hakko for a while, but it did not persist. ~ GE
