legendary for his encyclopaedic knowledge of kata and their bunkai applications. By the 1920s, he was regarded as the foremost authority on Okinawan kata and their history and was much sought after as a teacher by his contemporaries. There is even some evidence that his expertise was sought out in China, as well as Okinawa and mainland Japan. As a police officer, he taught local law enforcement officers and at the behest of his teacher Itosu, began instruction in the various grammar schools in Shuri and Naha. Shito-ryu history In an effort to popularise karate in mainland Japan, Mabuni made several trips to Tokyo in 1917 and 1928. Although much that was known as 'Te' (Chinese Fist) or Karate had been passed down through many generations with jealous secrecy, it was his view that it should be taught to anyone who sought knowledge with honesty and integrity. In fact, many masters of his generation held similar views on the future of Karate: Gichin Funakoshi (船越義珍)(founder of Shotokan (松濤館)),another contemporary, had moved to Tokyo in the 1920s to promote their art on the mainland as well. During this period, Mabuni also taught many other prominent martial artists, such as Otsuka Hironori (founder of Wadō-ryū) and Yasuhiro Konishi(founder of Shindō jinen-ryū). Both men were students of Funakoshi. 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'. In an effort to gain acceptance in the Japanese Butokukai, the governing body for all officially recognised martial arts in that country, he and his contemporaries decided to call their art 'Karate' or 'Empty Hand', rather than 'Chinese Hand', perhaps to make it sound more Japanese. Around the same time, perhaps when first introducing his style to the Butokukai, is when it's believed the name of the style changed to Shitō-ryū, in honour of its main influences. Mabuni derived the name for his new style of Shitō-ryū from the on'yomi readings of the first Kanji character in their names, "Shi" for Ito("shi")su and "To" for Higashi("to")onna. With the support of Sakagami Ryusho (1915-1993), he opened a number of Shitō-ryū dojo in the Osaka area, including Kansai University and the Japan Karate-dō Kai dojo. To this day, the largest contingent of Shitō-ryū practitioners in Japan is centred in the Osaka area. However, Mabuni's contemporary Shinpan Shiroma remained in Shuri, Okinawa,
