Fight card

Report

At the historic Ryogoku Kokugikan, RISE staged one of its biggest cards of the year — and crowned a new bantamweight king. In the main event, Koki Osaki dethroned long-reigning champion Shiro, the division's polished technician, scoring a third-round knockdown on his way to the belt.

It was sweet revenge: Shiro had beaten Osaki in their 2022 first meeting. The result signaled a changing of the guard in one of Japanese kickboxing's deepest weight classes.
