KNOCK OUT.57 takes place on September 23, 2025, in Japan.

RISE’s biggest match of the year, “ELDORADO,” takes place on Saturday, March 28, at Tokyo’s Ryogoku Kokugikan. Top RISE all-stars shaping the current era of striking martial arts—including Shirō, Kento Haraguchi, Taiju Shiratori, and Ryūjin Nasukawa—will gather under one roof. The main event is a supreme title clash: RISE World Bantamweight Champion Shirō faces the 8th RISE Bantamweight Champion Koki Osaki. The two first met in October 2022, when Shirō won by an extension decision. Since then, Osaki has built a winning streak and earned another shot, making this a long-awaited revenge match. Will the champion remain an unbreakable wall, or will the challenger’s three-year determination finally claim the world belt?
