Numsurin Chor Ketwina carries no pressure into his November 16 collision with 10-time Muay Thai World Champion Nadaka at ONE 173: Superbon vs. Noiri inside Tokyo’s Ariake Arena, where the Thai striker battles Japan’s greatest atomweight star for the inaugural ONE Atomweight Muay Thai World Championship knowing everyone expects him to lose.
That underdog status provides freedom rather than burden. While Nadaka enters as heavy favorite, Numsurin sees opportunity where others see mismatch — his chance to claim ONE Championship gold exists precisely because the newly created division opened doors that remained locked throughout his career.

“I want to be a World Champion. It has been my dream for a long time. There is a newly opened opportunity for this weight [class]. That is something I yearn for,” Numsurin said. “There’s no pressure for me because I am the big underdog. I am chill but deep down, I hope that I will get it. ONE’s Muay Thai belt is globally renowned. If I get it, I will be more famous.”
His path to victory requires solving problems the Japanese star presents through speed and precision. Numsurin’s extensive study of Nadaka revealed dangerous attributes that compensate for any lack of raw power — fast footwork creating angles, accurate strikes landing consistently, volume overwhelming opponents who can’t match the pace.
“His fighting style includes fast footwork and accurate weapons. Even though they’re not very powerful, they can [knock] you to the ground. His strengths include speed and accurate weapons,” Numsurin said.

The Thai veteran believes his answer lies in superior punching power. While Nadaka accumulates damage through precision and volume, Numsurin possesses heavier artillery capable of ending fights when opportunities emerge. His camp preparation focused on developing speed to match his opponent’s quickness while remaining patient enough to capitalize on openings for his most dangerous weapons.
“My strength would be my punches. I do have a plan to put him down. I’m working on my speed in order to cope with his speed. He is a very nice guy. But on the stage, there could be no mercy,” Numsurin said.
History awaits the victor. Whoever claims victory on November 16 becomes forever remembered as ONE Championship’s first atomweight Muay Thai king, their name permanently etched into the organization’s legacy as the division’s inaugural champion.
