at that time included Higaonna Kamesuke and Marukawa Kenji. In addition, his guest students were Yasuhiro Konishi, Hironori Ōtsuka, and boxer champion "Piston" Horiguchi. Motobu had no small amount of difficulty in teaching karate in terms of language. He moved to mainland Japan after the age of 50, so he was forced to teach exclusively in the Okinawan dialect at the dojo. As a result, those who were not pleased with his success spread a rumor that he was illiterate. This rumor has been largely discredited by the existence of samples of Motobu's handwriting, which is in a clear and literate hand. In a Tsunami video production on Motobu-ryū, Motobu Chōsei comments that his father's language difficulties may have been motivated more by protest at being a displaced member (by the Japanese annexation of Okinawa) of the Ryukyuan aristocracy than by inability. In the fall of 1936, Motobu temporarily closed his Daidōkan dojo in Tokyo and returned to Okinawa. He then attended a roundtable meeting of karate grand masters held in Naha on October 25. He stayed in Okinawa for a while and returned to Osaka the following year. There he began teaching karate to his son Motobu Chōsei. Motobu occasionally traveled to Tokyo to teach karate, but due to deteriorating health he closed his dojo in the fall of 1941 and returned to Osaka. In June 1942 he taught karate briefly at the Tottori Agriculture High School (present-day Tottori University Faculty of Agriculture). Return to Okinawa After moving to mainland Japan, Motobu occasionally returned to Okinawa for short periods of time. In late 1926 and 1927, Motobu returned briefly to Okinawa. On January 7, 1927, Motobu demonstrated wood-board breaking and kumite in front of Kanō Jigorō, the founder of judo, who was visiting Okinawa. He was introduced as "Okinawa's Number One" in kumite and was greatly admired by Kanō. In late 1936, Motobu returned briefly to Okinawa again and attended a roundtable discussion of karate masters in Naha on October 25. In November, he also attended a roundtable discussion organized by young Okinawan karate practitioners. Motobu was invited as the most practical karate master. In late 1942, Motobu returned to Okinawa, hoping to die in his hometown. He died in April 1944. Motobu's legacy and notable students Motobu Chōki's third son, Chōsei Motobu (1925- ), still teaches the style that his father passed on to him. As a point
