The venue for super bantamweight champion Toshiaki Nishioka's sixth title defense in a WBC world tripleheader on April 8 will be moved from Tokyo's Ryogoku Kokugikan to Kobe World Memorial Hall, Teiken Gym and Shinsei Gym jointly announced on Thursday.
Fight organizer Teiken Gym said it had made the move as a safety precaution following the March 11 earthquake and tsunami. Western Japan has not been affected by the quake.
Nishioka will face off against sixth-ranked challenger Mauricio Munoz of Argentina. Featherweight champion Hozumi Hasegawa will meet top-ranked challenger Jhonny Gonzalez of Mexico, while super featherweight champion Takahiro Ao will take on Mexican Humberto Gutierrez, ranked third in the world.
It will be the first time that three Japanese champions have defended their titles together at the same venue.
