From what we understand Watanabe Gym, the gym that manages Kono, do want to try and get the fight in Japan though with Kameda's licensing issues it may be difficult. In theory Kameda could possibly fight as a foreign fighter in Japan, like the many visiting boxers who fight there, though that may come with notable knock on issues and possibly even end up being unsanctioned by the JBC.
As for Kameda it's likely that if his team wins the purse bids the situation is going to force them to fight on the road with the Philippines, Mexico and the USA all possible for the bout.
With the bout being an open purse bid there is also the option of a third party winning the purse bid. This may mean that Warrior Boxing, for example, could snap up the fight and put the the fight on the undercard of Tomoki Kameda's WBO Bantamweight mandatory title defence against Alejandro Hernandez. Likewise it may be a possibility for Bob Arum to snap up the fight and put it on his upcoming Macau show.
Thinking about it in depth it may make a lot of sense for Arum to pick up the fight. Not only would it add yet more allure to the November 22nd show in Macau but it would also show case the winner who would likely be a target for Rex Tso in 2015. Likewise Frank Warren may have an interesting in bringing the title over to the UK in an attempt to get Paul Butler to fight the winner next year, whilst OnesongChai could be viewing the winner as an opponent for the destructive Srisaket Sor Rungvisai or ALA who may try and match the winner with the unbeaten Arthur Villanueva
It may seem silly but this purse bid could end up being one of the most interesting in recent years with various third parties
