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' (Hand) 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(糸)su and "Tō" for Higashi(東)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 dōjō. 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, and established Okinawan Shito-ryu. ==Career==
