Nadaka Yoshinari arrived at ONE Championship in 2025 already carrying ten world titles from Thailand’s most unforgiving venues. The 24-year-old Japanese striker from Eiwa Sports Gym could have coasted on those credentials. Instead, he went 4-0 across the year with performances that made technical mastery look like the easiest thing in the world.
His promotional debut at ONE 172 in March answered any questions about whether those Thai titles translated globally. Former Lumpinee kingpin Rak Erawan spent three rounds discovering that Nadaka’s striking repertoire included everything advertised until a straight left dropped him with twenty seconds remaining, punctuation on a masterclass.
Three months later at Lumpinee Stadium, Banluelok Sitwatcharachai learned the hard way about fighting complete technicians. Nadaka’s movement created distance when pressure arrived, his feints froze attacks before they launched, his counters landed with surgical precision. The unanimous decision ended Banluelok’s 3-0 slate while confirming Nadaka belonged in any conversation about the division’s elite.
August brought Hamada Azmani’s heavy artillery, which troubled the Japanese fighter enough through two rounds to suggest possibilities. Round three lasted fifteen seconds before Nadaka’s creative combinations settled the discussion.
But November at Tokyo’s Ariake Arena delivered what 2025 had been building toward. Numsurin Chor Ketwina arrived for the inaugural ONE Atomweight Muay Thai World Championship carrying over 100 career victories and a perfect 6-0 ONE record. Nadaka controlled five rounds with the kind of technical dominance that makes judges’ work simple — all three scored it his way, delivering an eleventh world title while extending his winning streak to forty consecutive victories.
Four fights, four wins, one title, forty straight. The mathematics don’t lie, even when they seem too perfect to believe. ONE Championship’s 2025 Muay Thai Fighter of the Year recognition merely confirms what the scorecards have been declaring since March.
