My wife did some research recently that identified the lineage of Kitagawa sensei. Kitagawa sensei was a direct student of Itosu sensei, as was Funakoshi sensei. Where Funakoshi sensei focused on popularizing karate as a sport and bringing it to the masses, the only record of Kitagawa sensei teaching anyone was six or eight teenaged boys at the New Denver internment camp in 1945 to 1948. He called his art "Okinawa Te", or "Kumite". It appears that he may not even have been aware of the branding of the art as karate until after the war. Where Funakoshi sensei modified the katas to be easier to teach to large numbers of students, Kitagawa is not believed to have modified the katas much at all. Kitagawa was teaching survival, not recreation. He did not receive payment for instruction. His emphasis was on stoicism, endurance, speed, and power.
