I study Old Shorin Ryu Karate from Okinawa. My Linage is Chosin and Usi Sakugawa. My father was a Marine in charge of refueling ships in the Pacific theater during the Battle of Okinawa WWII. Then he was stationed in Burma China, Indonesia, and Hawaii. He brought Sakugawa Shorin Ryu to the U.S.A. (Dallas Texas) and started the first Shorin Ryu school there in the early 1950's I trained first with my father then when he passed on in the 80's I studied with his students.
