This study aimed to provide legal and systematic proposals on developing, organizing, and running after-school sports programs in Korea by analyzing the relation between regular courses of study and active after-school sports clubs in Korea and Japan. To achieve the purpose of this study, the study was analyzed and developed based on the following. First of all, an analysis was made on the national-level curriculum activities in Korea and the national curriculum in Japan. Specifically, an analysis was conducted focusing on the revised curriculum in 2009 and the 2008 new national curriculum in Japan. Secondly, an analysis was made on cases of after-school sports clubs in Korea and Japan, and the study was developed by identifying the details of specific after-school sports club activities through cases that did not appear in the revised curriculum in 2009 and the 2008 new national curriculum in Japan. Thirdly, after-school sports club activities in Korea and Japan were explored and implications were derived. In conclusion, future physical education and after-school sports club must fulfill the naturally occurring desires of students and satisfy the needs of the society. In addition, physical education curriculum and high quality sports club programs must be prepared, and must enable people to continuously engage in sports activities in the society as well. For this purpose, various analyses and effective operating measures must be sought out at the scene, and their legalization must be carried out accordingly.
