The southern kata have their origins in Goju Ryu karate, which Oyama learned while training under So Nei Chu and Gogen Yamaguchi.
The kata Gary(r)u is not taken from traditional Okinawan karate but was created by Mas Oyama and named after the village where he was born in
Several kata are also done in "ura". This means that on every other step forward, the practitioner slides his back leg behind his front leg and around to the position it would have been in had he stepped forward. This in effect produces a spin on one foot.pinan sono ichi ura
