It's difficult to predict the winner of this fight, but even as a newcomer to the world of boxing, if I were to bet on a fighter, I would bet on Inoue's victory. On December 25th of last year, he defeated David Picasso, and before that, he defeated Murodjon Akhmadaliev. On the other side, we have Junto Nakatani, who is also on a winning streak, having defeated Sebastian Hernandez Reyes, and before that, Ryosuke Nishida. Both fighters are skilled, but I see Inoue as the boxer who will emerge victorious.
Not difficult as what we say, boxers are only good as in their last fight. As you have said, Nakatani beat Hernandez but it looks like the boxing community is split with the decision. Even in the other community when I posted this, they are saying that Nakatani could have lost his fight.
So skill per skill Inoue is going to be the favorite here. Nakatani though is like a torn on Inoue so he needs to show not just in Japan, but in the boxing world that Naoya is the best boxer right now coming out from that country. And if it live up to the expectations, this could be a fight of the year candidate and Inoue might be the fighter of the year if he is going to win the war.
