The bantamweight title fight, between WBC champion Shinsuke Yamanaka (15-0-2, 11KOs) and challenger Vic Darchinyan (37-4-1, 27KOs), has received two big supporting bouts for their undercard. The card takes place on April 6 at the Tokyo International Forum in Tokyo, Japan.

Takahiro Aoh will defend the WBC super featherweight title against Thai veteran Terdsak Kokietgym (46-3-1, 31KOs). Kokietgym has won seventeen straight since losing a twelve round decision to then WBO featherweight champion Steven Luevano in March 2008.

Former featherweight champion Hozumi Hasegawa (29-4, 12KOs) will return in his first ring out since getting knocked out by Jhonny Gonzalez last April. He faces undefeated Felipe Carlos Felix (18-0, 10KOs) from Mexico.
