Itsuki Hirata and Jihin Radzuan set for rematch at ONE SAMURAI 4

ONE Championship has announced a women's atomweight MMA rematch between Itsuki Hirata and Jihin Radzuan for the ONE SAMURAI 4 event. The bout is scheduled for Saturday, October 17, 2026, at the Ariake Arena in Tokyo, Japan.

The matchup serves as a rematch of their 2022 encounter at ONE Xin, where Radzuan secured a split-decision upset victory over the Japanese favorite. Hirata, currently holding an 8-5 professional record, seeks to avenge that loss and re-establish her position in the atomweight division, which is currently without a champion following the title vacancy of Denice Zamboanga.

Radzuan enters the fight with a 10-5 professional record and nine victories within the promotion. The outcome of this contest is expected to significantly impact the rankings and the pursuit of the vacant ONE Women’s Atomweight MMA World Title.
