Sadly we've been unable to get images from the weigh in but we have been informed that both men made weight for the bout, and that the bout will go ahead planned.
For Hayashi the bout serves as his second defense, following a major win at the end of 2016 over Akifumi Shimoda, and could potentially be a final step before he and his team begin to pursue an OPBF title fight. Coming in to this one Hayashi is riding a 15 fight unbeaten run, including victories over Shimoda, Noriyuki Ueno and Koji Umetsu.
As for Saka this will be his first title fight, and although the under-dog he comes into the bout on a 7 fight stoppage run including notable domestic wins over Ryuto Kyoguchi and Takafumi Nakajima. This is a step up but he's proven his power is legitimate and he's proven to be one of the under-the-radar Japanese fighters who have caught our eye in the last 18 months or so.
Hayashi and Saka battle for Japanese crown in potential thriller!
