International Boxing Federation’s top-ranked female minimumweight Sana Hazuki of YuKO Fitness Boxing Gym in Fukuoka Prefecture, southwestern Japan, will challenge champion Yokasta Valle of Costa Rika for the latter’s title on Jan. 30 in the central American country, according to Costa Rican boxing sources.
The scheduled 10-rounder will probably be held at Oxigeno Human Playground in the city of Heredia behind closed doors.
While the 28-year-old Valle was initially supposed to face WBC minimumweight champion Tina Rupprecht of Germany in a title unification bout, the IBF did not agree and ordered her to defend the title against the mandatary challenger.
Valle has a record of 20 wins, including nine knockouts, against two losses, while the 36-year-old Hazuki has an eight-four-one win-loss-draw record with two KOs. She is currently the Oriental and Pacific Boxing Federation minimumweight champion.
Valle once visited Japan as she lost to Naoko Fujioka of Shinji Takehara and Takanori Hatakeyama Boxer Fitness Gym for the vacant World Boxing Organization light flyweight title in December 2017 at Tokyo’s Korakuen Hall.
