Nakatani has been the OPBF champion since January 2014, when he beat Yoshitaka Kato, and has since run up a string of defenses against a mix back of opponents. His first defense saw him defeat Ricky Sismundo, in what was a really impressive performance, but since then wins over the likes of Accel Sumiyoshi, Allan Tanada and Ryan Sermona have done little to enhance the champions reputation. In fact in the eyes of many who have followed his career it does seem like Nakatani's career has stalled, when it should have been built on following early career wins over Kato, Sismundo and Shuhei Tscuhiya.
As for the youngster he was a former amateur standout who turned professional with a little bit of hype. He looked great in his early bouts, shining particularly brightly against Shun Shimazaki in his third bout. He would claim the Japanese the Japanese Youth Lightweight title in just his 4th bout, defeating Yuichiro Kasuya, and would defend the title twice, with his second defense being a technical draw against Kaki Yuba in February.
For Nakatani a win will be expected, but he'll have to show how he can cope with a slippery, boxer mover. As for Tomioka the bout is a massive step up in class, but a win will put his name on the boxing map.
For fans interested in watching this contest, it will take place at the EDISON Arena Osaka, in Osaka city, the home city of the champion.
