was a Japanese master of aikido who founded the Yoshinkan style of aikido. He was one of aikido founder Morihei Ueshiba's most senior students. Shioda held the rank of 10th dan in aikido. Early life Shioda was born on September 9, 1915, in Shinjuku, Tokyo. His father was Seiichi Shioda, a physician who also taught judo and kendo. Shioda was a weak child, and reportedly credited his survival to his father's pediatric skills. While still at school, Shioda trained in judo, attaining the rank of 3rd dan before completing secondary school. He also trained in kendo during his youth. Aikido career Shioda began training under the founder of aikido, Morihei Ueshiba, in 1932. His training as an uchi-deshi (live-in student) under Ueshiba continued for eight years. Shioda was a small man, standing at around 5' 1" to 5' 2" (155–157 cm) and weighing around 102 lb. to 108 lb. (46–49 kg). Shioda graduated from Takushoku University, where he went to class with Judo master Masahiko Kimura and Kyokushin Karate founder Mas Oyama, in 1941, and was posted to administrative positions in China, Taiwan, and Borneo during World War II. In one incident in China, he was drinking in a bar with an army friend in Shanghai when the friend got into an argument with a local gang member. Three of his fellow gang members came to his assistance. Shioda and his friend were cornered by the gang. In the ensuing fight, Shioda broke the leg of one of the gang members, the arm of another, and stopped another by punching him in the stomach, all using his aikido skills. Shioda later described this incident as his 'aikido enlightenment' and wrote that one could only truly appreciate what aikido was about once one had used it in a life-or-death situation. Shioda returned to Japan in 1946 and spent several months trying to locate his family on Kyushu. He rejoined Ueshiba for a month of intensive training, but was forced to dedicate the next few years to earning a living in post-war Japan. He began teaching aikido in 1950. That year, he taught for the company Nihon Kokan at the Asano Shipyards in Yokohama. In 1954, he entered the All Japan Kobudo demonstration, and won the prize for the most outstanding demonstration. This marked a turning point for the growth of aikido. Shioda's performance attracted sponsorship that enabled him to build an
