Pa Sai Dai
The name pasai means "To Breach or Break Through". The versions practiced most in Shuri-te styles are the Matsumura versions. Some claim that Bushi Matsumura created both of these, probably from pre-existing kata he got from Yara and Sakugawa. There are other versions out there that vary dramatically, so it is likely that the kata was around before Matsumura's time. The Matsumura Seito versions come the closest to Matsumura's personal version than any others.
