Isshin-Ryu (一心流, Isshin-ryū?) is a style of Okinawan karate founded by Tatsuo Shimabuku and named by him on 15 January 1956. Isshin-Ryū karate is largely a synthesis of Shorin-ryū karate, Gojū-ryū karate, and kobudō. The name means, literally, "one heart method." As of 1989 there are 336 branches of Isshin-ryū throughout the world, most of which are concentrated in the United States. After the death of Shimabuku in 1975, many variations of Isshin-ryū were formed.

From the way we block to the way our fist is held and thrown is all unique to Isshin Ryu, not just Okinawan karate. Today with all the commercial martial art schools, we must maintain our tradition and value that a true art has to offer.
