Today the two men took part in the weigh in for their bout and both made weight on their first attempt.
The defending champion was just under the limit for the bout, which will be his third defense of the title, and looked in tremendous shape for the contest which he seems really up for, something that hans't been the case for his last two bouts which have been seen him put in relatively flat performances.
Naito on the other hand was bang on the divisional limit for the bout and although he looked in great shape it did seem like he was less ripped than the champion. For Naito the bout is a chance to avenge his sole defeat, but he really has shined in recent years and some are suggesting he has peaked already and is on the way down.
Sadly for fight fans outside of the Korakuen Hall this bout isn't being televised live.
Ogawa looks for a repeat, Naito looks for revenge!
