OSAKA -- Champion Masamori Tokuyama, a pro-Pyongyang Korean resident of Japan, will fight former champion Cho In Joo of South Korea on May 20 for the World Boxing Council super-flyweight title.

Tokuyama, whose Korean name is Hong Chang Soo, will attempt to make his second title defense either in Pyongyang or in Seoul, Hideo Kanazawa, head of the gym where the champion trains, said Tuesday.

Kanazawa said he hopes that an agreement on a venue can be reached with the Cho camp later this month. Tokuyama took a unanimous points decision from Cho last August to win the championship belt, then won a one-sided fight against fifth-ranked challenger Akihiko Nago of Japan in December for his first title defense.
