ONE SAMURAI 1

A historic fight week has reached a critical point. The elite field of martial artists set to compete at ONE SAMURAI 1 has one final box to check before the action can begin at the Ariake Arena in Tokyo, Japan.

The event takes place this Wednesday, April 29, but every athlete must successfully weigh in and pass their hydration tests to ensure they’re healthy and ready to compete at their absolute best.

Fans can watch the official ONE SAMURAI 1 Weigh-Ins & Hydration Tests by clicking the video below beginning at 10 a.m. Japan Standard Time on Tuesday, April 28.

Tokyo is in for a historic night. Four World Titles are on the line across kickboxing, mixed martial arts, and Muay Thai, headlined by one of the most anticipated rematches in ONE Championship history.

In the main event, Rodtang “The Iron Man” Jitmuangnon and Takeru “Natural Born Krusher” Segawa will meet for the second time – and the ONE Interim Flyweight Kickboxing World Title is up for grabs.

Their first encounter at ONE 172 in March 2025 lasted just 80 seconds, as Rodtang landed a pair of left hooks and dropped the hometown hero in stunning fashion. That result has haunted Takeru ever since. After winning his next bout and publicly announcing his plans to retire, the Japanese superstar made one final request: a rematch with “The Iron Man.”

Now, both men have everything to fight for. Takeru wants to even the score and leave the sport with ONE World Title gold around his waist. Meanwhile, Rodtang, who will be making his final appearance in ONE, has the chance to beat the beloved Japanese icon twice and finally achieve two-sport glory.

In addition, ONE Flyweight MMA World Champion Yuya “Little Piranha” Wakamatsu makes his second World Title defense in front of his home crowd against the unrelenting Avazbek “Ninzya” Kholmirzaev.
