Whilst little is known about Takuma's opponent, we'd be expecting a ranked Japanese fighter as Takuma looks to move towards a Japanese title fight.
For Naoya things are a lot more interesting. It seems that Naoya is likely to get a world title fight with staff at the Ohashi gym currently working hard to get the youngster a bout at the very highest level. The idea is to let Naoya become the national record holder for the fighter with the fewest fights to become a world champion, a record currently held by Kazuto Ioka who took 7 fights.
At the moment details are scarce as to who Naoya will be fighting though we feel that we can rule several men out, including WBO champion Donnie Nietes (who looks set to defend against Moises Fuentes), IBF champion Johnriel Casimero (who is set to defend against Mauricio Fuentes) and maybe even WBC champion Adrien Hernandez (who fights in February against Janiel Rivera).
In theory this would leave only Kazuto Ioka as a plausible foe for Inoue though we believe Ohashi trying to lure one of the other 3 champions over to Japan in a hope that a bigger purse will sway them away from their currently scheduled bouts. Of the 3 champions with a scheduled bout we imagine that Hernandez would be the most likely to be able to take the bout with Rivera really not being a "world level" opponent and even if Hernandez does take on Rivera he could very well be free for April
It would come as no shock at all if the Inoue brother's, pictured together, were on the same card as Yaegashi, with the trio being able to fill a big arena and really celebrate Ohashi Gym's anniversary, which seems to be the aim of anything that happens in April. In fact if the right fights do end up being made this could be one of the best cards of the year. Though of course with the card being mere speculation at the moment this could also be a card that ends up falling flat.
