From what we understand the decision was made due to a number of reasons, though they were effectively all effectively that the JBC was worried that the gym wouldn't be able to control Kameda. They seemed to feel that if Kameda was given the requested transfer the gym would later become a new Kameda gym as opposed to remaining UNITED.
It would seem that the only way Kameda will get a transfer accepted would be if he moved to a more established gym, for example Teiken, Ohashi, Watanabe or Kadoebi. Unfortunately for Koki there are issues with almost everyone of those possibilities. For example signing with Watanabe would prevent him getting a fight with Kohei Kono whilst personal feelings between Koki and Hideyuki Ohashi would likely prevent him going to Ohashi.
The JBC have stated that they will look over future applications for a transfer request from Koki though at the moment it appears that the fighter won't be fighting in Japan any time soon.
Unfortunately this decision continues to leave the aforementioned Kono (30-8, 13) in limbo with Koki currently his mandatory. We're still hoping the WBA will make the right decision and allow Kono to have a voluntary defence whilst Koki sorts out his issues though at the moment the issue is just becoming a mess that won't go away.
We'd suspect that if Koki wants to continue his career he will have to follow in the footsteps of younger brother Tomoki and begin fighting in the west. Unfortunately however there is little interest in the 115lb division in the US and the money Koki would be getting would certainly be limited if he took that option.
At the moment Koki's future really is up in the air though in some ways it's nice that the JBC are making an example of Koki and the Kameda clan who have been a thorn in their side for a number of years. It may seem harsh but boxing has become a sport with very few "real" punishments and we've seen drug cheats suffer little more than a slap on the wrist so this may well prove that running the sport with a backbone is actually a really effective measure in keeping fighters in check.
