Nadaka Yoshinari Retains Atomweight Title at ONE Samurai 4
Japanese fighter Nadaka Yoshinari successfully defended his ONE Muay Thai Atomweight title by knocking out Malaysia's Reefdean Masdor in the second round in Tokyo.
On October 17, 2026, Japanese Muay Thai champion Nadaka Yoshinari successfully defended his ONE Atomweight world title at the Ariake Arena in Tokyo during the 'ONE Samurai 4' event. Nadaka faced Malaysian challenger Reefdean Masdor in a bout that saw significant pre-fight complications.
According to reports from Khaosod Online, the championship status was effectively decided before the fight began. Reefdean Masdor failed to meet the required weight limit during the official weigh-in, resulting in a compensatory payment to Nadaka. Consequently, Nadaka retained his title regardless of the match outcome, while Reefdean was rendered ineligible to win the belt.
Despite the pre-fight controversy, the match proceeded as scheduled. Nadaka demonstrated his dominance early, securing a knockout victory just 58 seconds into the second round. The referee stopped the contest after Nadaka sent his opponent to the canvas, confirming his continued reign as the division's champion.
For residents and visitors in Japan, this event highlights the high-level professional combat sports scene currently active in Tokyo. While the title defense is now concluded, fans may look forward to future ONE Championship announcements regarding Nadaka’s next challenger. No further details regarding potential disciplinary actions or future weight-class adjustments for Reefdean have been confirmed at this time.
