By 1929, Mabuni had moved to Osaka on the mainland, to become a full-time karate instructor of a style he originally called Hanko-ryū, or "half-hard style". The name of the style changed to "Shitō-ryū", in honor of its main influences. Mabuni derived the name for his new style from the first kanji character from the names of his two primary teachers, Itosu and Higaonna (also called Higashionna). With the support of Ryusho Sakagami (1915–1993), he opened a number of Shitō-ryū dojo in the Osaka area, including one at Kansai University and the Japan Karatedō-kai dojo. To this day, the largest contingent of Shitō-ryū practitioners in Japan is centered in the Osaka area.
