Earlier today the two men took part in their weigh in for the contest, and both fighters made weight for the bout, with both coming in comfortably under the 122lb limit.
The champion came in the heavier man, coming in around 121.75lbs, and looked in great shape whilst promising a clear win. This will be his second defense of the title, and he seemed somewhat unhappy at having scored split decisions in both his title win, against Ryota Ishida, and his first defense, against Yuki Iriguchi.
Maniwa on the other hand was around 121.5lbs and comes into this bout on a 6 fight winning streak, though his best ins have been against Yu Konomura and Masami Morisaki, so we're unclear how good he really is.
