Isshin Style: Isshin-Ryu is a style of Okinawan karate founded by Tatsuo Shimabuku in 1956. Isshin-Ryu karate is largely a synthesis of Shorin-ryu karate, Goju-ryu karate, and kobudo.

The name means, literally, "one heart way" (as in "wholehearted" or "complete"). In 1989 there were 336 branches of Isshin-ryu throughout the world (as recorded by the IWKA), most of which were concentrated in the United States.
