We had, a few weeks ago, speculated on it being OPBF #1 contender Vinvin Rufino (34-15-3, 16) and today that bout was confirmed.
Amagasa, a freakishly tall Featherweight, won the title last year when he upset former world champion Ryol Li Lee. This will be his first defense.
Whilst Amagasa will be making his first defense Rufino will be making his second challenge at the title having previously been beaten, albeit narrowly, by Naoki Matsuda. That bout, back in 2010, was his last contest in Japan where he is currently 2-1, though on the road Rufino has lost his last 4 and is win less away from home since 2008.
As well as the Amagasa/Rufino bout this card will also feature Hidenori Otake (21-1-3, 9) defending his Japanese Super Bantamweight title against Takafumi Nakajima (22-6-1, 9), the highly touted Kazuma Sanpei (9-0, 3), the highly promising Ryuto Maekawa (7-0, 4) and model-turn-boxer Tomomi Takano (4-0, 3). The opponents for these 3 unbeaten fighters are yet to be announced.
