became a professor at Kenkoku University. Following the surrender of Imperial Japan in 1945, Tomiki was detained by Soviet Red Army troops and was held in a three-year internment by the Soviet Union. Post-war Tomiki was released from internment in 1948 and subsequently returned to Japan. In 1949, he became a part-time lecturer at Waseda University's Physical Education Department. He would teach Judo and Aikido for many years at Waseda University. It was there that he formulated and expanded his theories concerning both kata based training methods and a particular form of free-style fighting which would put him at odds with much, but not all, of the aikido world. It was this action on the part of Tomiki of attempting to convert aikido into a sport that led to a schism with the founder Morihei Ueshiba and the Aikikai. Tomiki was urged by the Aikikai to adopt a different name for his art other than “aikido” if he intended to introduce such a system of competition. Convinced of the need to modernize aikido, he stood his ground and persisted in his efforts to evolve a viable form of competition. In 1952, he was selected as one of the members of the Kodokan Goshinjutsu Enactment Committee. Tomiki is perhaps best known in the judo world for his influence in the developing of Kodokan Goshin Jutsu kata. His work Judo is considered a classic. The aikido appendix to the book is thought to be the earliest English language text on aikido. In 1953, Tomiki along with 9 other martial art instructors were selected to tour US Air Force bases in the United States and was thus the first aikido instructor to visit the US. In 1954, he became a professor at Waseda University. Between 1955 and 1959, he helped formalize the Self-Defense Forces unarmed fighting system (Jieitaikakutojutsu). In 1958, Waseda University Aikido Club was established and became the first director. On same year, he published the book “Aikidō nyūmon” (『合気道入門』 - Eng. "Introduction to Aikido"). In 1961, Tomiki almost formalized aikidō kyōgi/competitive Aikido. In 1964, he established "Physical Education Specialization" in the Department of Education, Faculty of Education, Waseda University, and became the chief professor. In 1967, Tomiki opened his Shodokan honbu Dojo which he used as a testing ground for his theories on aikido and competition. Tomiki followed Ueshiba as the Aikido division head of the Kokusai Budoin-International Martial Arts Federation
