Today the two men made weight for the bout, with both making the limit on their first attempt.
At the weigh in Yamanaka was the heavier man, coming in at 53.4KG's, which is close to 117¾lbs. The champion was a very similar weight a 11 months ago when he beat Diego Ricardo Santillan, though has usually been a little heavier often being bang on the limit.
Solis was slightly heavier, weighing in at 53.3KG's, or 117½lbs. Although a former Super Flyweight champion a lot has been made about Solis's weight by the Japanese press as he failed to make weight last time he was in Japan, weighing 117½lbs for a Super Flyweight unification bout against Daiki Kameda back in 2013. Unlike that bout, Solis has been professional, and been seen "guzzling coca cola", as he was last time he was in Japan.
