The following sums up this research on the suppression of Korean Physical Education under the rule of Japanese imperialism. 1. According to the educational policy of the Japanese colonical rule, physical education was employed as a tool for Japanizing Koreans under the false opinion that Koreans are a branch family of the Japanese. Therefore, the aim of sports education was to train loyal people of the clony. 2. The suppression took place in the form of changing the contents of curriculum and rigidifying the quality of physical education teachers. Thus, while the former gymnastics was changed into playing games and apparatus gymnastics devoid of national consciousness, many Japanese soldiers took the job of teachers. 3. The oppression also appealed in social sports in two ways. From May 1912 on, the collective athletic meeting came to an end in the name of financial difficulty and educational fallacy. In addition, many YMCA leaders were put into prison on the occasion of the 105-Man Incident in 1912, and the Korean YMCA was subjected to the Japanese YMCA the following year.
