This is a fight where experience will play a big factor in my opinion. Reiya Abe has had four times the amount of fights Takeshima has and has won the majority of them.
Koshin Takeshima is taking a second big step up in competition which I don’t think hes ready for honestly. He lost his last fight and while he competed he didn’t show enough to where he should be expected to win this one. Reiya Abe has been competing at domestic level in Japan for years and has had a lot of success while Takeshima has only been a pro for a few years.
I expect Reiya Abe to win by decision after eight rounds though if Takeshima has learnt from his last fight he could sneak a close decision win.
