Ikemizu had entered the bout as the #13 ranked Japanese Bantamweight and although he had been pushed hard by Satoshi Niwa he had come through all his tests so far, and also won the All Japan Rookie of the Year in 2013. This however was a big step up against a fighter known for giving young prospects real tests and "exposing" those who weren't as good as promoters had hoped. This had been seen in wins, in Japan, against Akihiro Matsumoto and Ryotaro Kawabata as well as a win over faded Thai Pramuansak Posuwan.
From the opening round this bout was fun with both guys going for it and from the second round onwards it seemed clear Yap was there to win rather than just make up the numbers. This resulted in a brilliant tear up between two men who took it in turns to hit each other before a tired looked Ikemizu was put into survival mode late on. Yap fought like a man who felt he needed a stoppage though in the end the judges got it right giving him a very narrow, but very well earned, decision with scores of 77-75, twice, and 77-76. Notably this ends a 3 fight losing run in Japan for Yap who is now fighting out of Japan and has a professional contract with a Japanese promoter, Muto Gym.
