History of Isshinryu Karate
Master Shimabuku had been experimenting with new approaches in karate for a long time. But with his energies focused on his art, Master Shimabuku’s creative spirit increasingly analyzed and synthesized all the kata, techniques and applications he had perfected. He continued the slow, methodical, thorough process of modifying Shorin-ryu and Goju-ryu into a style that he found more practical and effective. His experimentation was galvanized by his visionary dream of the Mizu-Gami. ( Master Arsinio J. Advincula, who spent many years studying in Master Shimabuku’s dojo is credited with designing the Isshin-ryu patch). The vision unified his ideas and his purpose. On January 15, 1956, Master Shimabuku publicly proclaimed that he would teach a new style called Isshin-ryu, one heart or whole-hearted way.
