Shudokan (修道館 Shūdōkan?), literally "the hall for the study of the way of karate," is a Japanese school of karate developed by Kanken Toyama (1888 – 1966). It was the total headquarters of Japan Karate Federation (old). Characteristics of Shudokan karate include large circular motions with an emphasis on covering and its own unique kata.
Toyama's karate training began at the age of nine in 1897 with Itarashiki, although he studied with Yatsusune Itosu for 18 years, until the latter's death in 1915. In 1907 Toyama was appointed "shihandai" (assistant master) to Itosu at the Okinawa Teacher's College, and he and Gichin Funakoshi, who later developed Shotokan karate, were the only two students to be granted the title of shihanshi (protégé). Some people believe that Kanken Toyama outranked Gichin Funakoshi, who did not have the rank of shihandai.
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. 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.
