The requirements for joining the J.League include items such as the stadium, management status, and team management status. Regarding team management, not only the team itself that actually participates in the J League game, but also the management obligation of the club youth team by the training organization (subordinate organization) are stipulated. From the 2013 season, the J-League club license system was launched, and the system for judging whether or not to join the J-League and the division that can join was updated.
