The purpose of this study is to clarify the issues and principles of National Sports Federation(the Sports Unification Bodies and the Sports Athletic Bodies) governance code, which was recently introduced by Japan for the first time. To achieve the purpose of the study, it conducted as a venue for discussion on the Sports Athletic Organizations of Governance Code Decision, the discussion process of the Sports Integrity Association, launched by the Sports Agency, which determined the code in its entirety. The result of the study is as follows. First, The discussion process took into account the principles and regulations related to sports governance abroad, based on problems caused by the dysfunction of governance of Japanese Sports Athletic Organizations. In order to make a more effective governance code, the discussion process included reporting the status of NF officials, as well as a hearing survey and gathering opinions from experts from all walks of life. Second, the Governance Code of Japan’s Sport Athletic Organization consisted of 131 detailed items based on 13 principles, each of which had a sole purpose, but could be confirmed to have a different principle and organic function. In particular, Principles 1, 2, and 3 occupy the core layers of the code as a whole compared to other principles. It is an essential principle that establishes a holistic and core framework for establishing governance of the NF. Based on the above three principles, the principles necessary for the actual situation of Japan as well as overseas were selected. Third, The governance code setting of Japanese sports organizations already has governance-related regulations such as the ideology of the Framework Act on Sports(Article 2) and the efforts of sports organizations(Article 5), making it easier to access code decisions. Furthermore, the recently established policy on sports integrity seems to have played an important role in organizing the system for establishing more governance for sports organizations ahead of the 2020 Tokyo Olympics.
