The two men, who fought earlier this year in a thrilling contest, are taking part in an immediate rematch and looked in great condition at the weigh in earlier today.
Although the weights haven't been publicly reported as of yet we have been informed that both made weight, and, from the picture we've seen, both looked ready to go in what promises to be an enthralling 12 round contest.
Whilst neither man will be regarded as the best Bantamweight in Japan they will each know that a win here will open up potentially career changing bouts with the likes of Ryosuke Iwasa and Shohei Omori who may be eyeing up the title in the near future.
