The rumour is that this bout will land in Japan in late Spring and be aired live on Fuji TV with Ohashi promoting the bout in Tokyo along with the first defense of the IBF Light Flyweight title by Inoue's stablemate Akira Yaegashi (23-5, 12) [八重樫 東].
Whilst Inoue does have a contractual obligation to face Argentinian veteran Omar Andres Narvaez (44-2-2, 23) it's thought that that bout will come in the summer in the US, with it being Inoue's US debut. The reason for that bout coming in the US is the fact that the pay day would be larger and the US audience are more aware of Narvaez than they are of Carmona, who was himself stopped in 7 rounds by Narvaez in 2013.
For Carmona this bout is a result of his controversial draw, last year, with Warlito Parrenas. Parrenas got a shot at Inoue last December, and was blown away by Inoue, and it's likely that Carmona will suffer the same fate when he faces Inoue.
