Kanken Tōyama

Kanken Tōyama (遠山寛賢 Tōyama Kanken, 24 September 1888 – 24 November 1966) was a Japanese schoolteacher and karate master, who developed the foundation for the Shūdōkan karate style.Born into a noble family in Shuri, Okinawa, Japan, he was given the name "Oyadameri Kanken".

Nine years old, he began his karate (Shuri-te) training under Ankō Itosu, and remained a student there until Itosu died in 1915.He also studied Naha-te under Kanryō Higaonna and Tomari-te under Ankichi Aragaki.

In 1924 Toyama moved his family to Taiwan where he taught in an elementary school and studied Chinese Ch'uan Fa, which included Taku, Makaitan, Rutaobai, and Ubo. Given this diverse martial arts background, the Japanese government soon recognized Toyama's prowess, and awarded him the right to promote to any rank in any style of Okinawan karate. An official gave Toyama the title of master instructor.

In early 1930 he returned to Japan and on March 20, 1930, he opened his first dojo in Tokyo. He named his dojo Shu Do Kan meaning "the hall for the study of the karate way." Toyama taught what he had learnt from Itosu and the Ch'uan Fa and did not claim to have originated a new style of karate. In 1946, Toyama founded the All Japan Karate-Do Federation (AJKF) with the intention of unifying the various forms of karate of Japan and Okinawa under one governing organization.
