ISSHINRYU KARATE
At our Safety First dojo, we are honored to continue the teaching of Isshinryu Karate as handed down from Sensei Stephen Armstrong, who learned this style directly from the founder, Tatsuo Shimabuku.
Tatsuo Shimabuku started studying martial arts at a very early age and in his lifetime, mastered many styles including Goju-Ryu, Shorin-ryu and various weapons.
He began teaching “Chan Migwha-te” (forerunner to Isshinryu Karate) to U.S. servicemen after World War II. It was during this time that Shimabuku began experimenting with new techniques to be quicker and faster. He used kendo protective equipment during kumite (sparring). He also started developing different ways to block and punch (most notably the vertical punch).
With the approval of his teachers, Shimabuku combined many techniques learned from those styles into his own style, and on January 15, 1956, officially announced the formation of Isshinryu Karate, meaning “One-Heart Way”, because according to him, “all things begin with One.”
An interesting note, Shimabuku’s chosen name of Tatsuo, means dragon.
It is by way of Steve Armstrong’s original schools that our dojo has as its highest ranking belt, Bill Kortenbach, 5th Dan, upon opening of our dojo on October 1st, 2006.
