5 Things To Know About Numsurin Before His Inaugural Atomweight Muay Thai World Title Clash With Nadaka At ONE 173
Thai tactician Numsurin Chor Ketwina has defeated every opponent he’s faced under the bright lights of ONE Championship – and now, he’s days away from the biggest fight of his career.
On Sunday, November 16, the TDed99 standout will meet Japan’s Nadaka for the inaugural ONE Atomweight Muay Thai World Title at ONE 173: Superbon vs. Noiri inside Tokyo’s Ariake Arena.
Before he steps into the Circle, here are five things you need to know about the 30-year-old star.
#1 He’s Undefeated In ONE Championship
Numsurin has quietly climbed the ladder to World Title contention, putting together a flawless record in the weekly ONE Friday Fights spectacle.
The TDed99 representative has compiled six consecutive victories in the world’s largest martial arts organization, showcasing sharp boxing, poise under fire, and strategic brilliance.
His most recent triumph came against Songchainoi Kiatsongrit at ONE Friday Fights 122, where he dropped the star in round two and ended his nine-fight winning streak. That victory earned Numsurin a US$100,000 main-roster contract, propelling him toward the biggest opportunity of his career at ONE 173.
#2 He Comes From Humble Beginnings
Born into a family of farmers in Thailand’s Sisaket Province, Numsurin grew up helping his parents in the fields alongside his two siblings.
He began competing in Muay Thai at just 9 years old after his uncle noticed his potential. At the time, he earned a mere 120 Thai Baht (less than US$4) for his first fight – money that went straight to support his family.
Those early experiences shaped his character and fighting spirit, instilling the work ethic and toughness that continue to define his approach to training and competition today.
#3 His Name Was A Happy Accident
While he’s proudly from Sisaket, the name “Numsurin” actually means “young man from Surin.”
The moniker came from a school teacher’s mistake, who assumed he was from Surin because he could speak Khmer, a common language in the area.
Numsurin initially planned to correct the error, but by the time he began winning fights, the name had already become part of his identity.
Rather than changing it, he embraced it as part of his journey – a symbol of his rise from humble beginnings to international acclaim.
#4 He Served In The Military And Became A Champion Among Soldiers
Before turning full-time to professional fighting, Numsurin spent a year serving in both the Thai Army and Thai Air Force.
Even while enlisted, his fighting prowess stood out. He won multiple Muay Thai accolades in internal military tournaments, often competing against fellow servicemen across the country.
That same discipline carried over to his academic pursuits. While studying at National Sports University, he captured the 2018 World University Muay Thai Championship, marking an early highlight in his competitive journey.
Today, he continues to give back to the sport as a Muay Thai and boxing instructor at Bangkok Sports School, nurturing the next generation of Thai athletes.
#5 He’s Building His Own Brand Online
Outside the ring, Numsurin has become one of Thailand’s most engaging athletes on social media, with over 100,000 Instagram followers.
Rather than chasing fame, he uses his platform to share his journey. He carefully conceptualizes and curates his content, believing social media is a vital tool for modern fighters to connect with fans and showcase the beauty of Muay Thai to the world.
Through humility, discipline, and digital creativity, Numsurin represents the new face of Thai martial artists – deeply rooted in tradition, yet forward-looking in every way.
