The ruling came in several parts:
Firstly the Kameda Gym, now known as "K3" will remain inactive. This will prevent any of the brothers from fighting in Japan for now. This is merely a continuation of a previous ruling that prohibited the Kameda's from promoting their own fights.
Secondly Shigeyuki Otake can, in the future, apply to run his own gym. The decision not to allow him to run the K3 gym is due to the fact that it's effectively the same as it was when the license was taken away and the Association seems to feel that that was the real problem.
Thirdly if the Kameda's want to fight in Japan they will have to join another gym. The alternative is to base themselves outside of Japan.
Fourthly, and most pertinently, the the Association will request the WBA do not push forward with attempting to make Kohei Kono (30-8, 13), the WBA Super Flyweight champion, fight Koki Kameda (32-1, 17). Whilst the bout could be made, for example in Macau or Singapore, the Association will request that Kono faces a change of opponent. If the WBA accept the request it's likely that Kono would be facing Mexican David Sanchez (25-2-2, 19) next, unless he is allowed to take a mandatory title defence.
Although the Kameda's can attempt to convince the West Japan Boxing Association that they've changed it would seem unlikely that the West Association would give the Kameda's a licence either and effectively this seems to be a decision that finally puts a nail in the Kameda's as a promotional outfit.
