ONE SAMURAI 3: Nadaka Yoshinari wins kickboxing debut

ONE Championship held the ‘ONE SAMURAI 3’ event at the Yokohama Buntai on September 12, 2026. In the main event, Atomweight Muay Thai World Champion Nadaka Yoshinari successfully transitioned to kickboxing, defeating Myanmar’s Har Ling Om via a 3-0 unanimous decision.

In the co-main event, former Flyweight MMA World Champion Yuya Wakamatsu secured a second-round TKO victory against South Africa’s Willie van Rooyen. The fight ended after a heavy left hook from Wakamatsu led to a doctor’s stoppage, reportedly due to a jaw injury sustained by van Rooyen. Wakamatsu earned a performance bonus of 7.5 million yen for the win.

Other notable results included Shimon securing a second-round knockout against Su Black in a Flyweight Muay Thai bout, and Haru winning a unanimous decision against Hiouma Hitachi in a Flyweight Kickboxing match.
