ONE SAMURAI 4 marks the return of ONE Championship to Tokyo’s Ariake Arena on Saturday, October 17, showcasing a stacked card across Muay Thai, kickboxing, submission grappling, and MMA. The event highlights Japan’s top talent alongside international contenders, promising high-stakes action from the opening bell. Jonathan ‘The General’ Haggerty defends his ONE Bantamweight Kickboxing World Title against Hiroki Akimoto in a clash of styles and pedigrees. The bout pits an unbeaten Haggerty, a former Muay Thai world champion, against Akimoto, a former champion seeking redemption after a resurgence in 2025.
Nadaka Yoshinari, the reigning ONE Atomweight Muay Thai World Champion, steps into the cage with a 42-fight winning streak and a technical arsenal built on speed and precision. His opponent, Rifdean ‘Magic Boy’ Masdor, carries a 7-1 record with a 71 percent finish rate and a four-and-a-half-minute average fight time. A victory for Yoshinari would cement his legacy, while a loss for Masdor could make him only the second Malaysian ONE World Champion in Muay Thai.
The Featherweight Kickboxing Tournament semifinals feature four elite strikers vying for a shot at the reigning champion Superbon. Marat Grigorian, a 35-year-old three-time Glory Kickboxing World Champion, faces Luo Chao in a clash of pressure and precision. Grigorian booked his semifinal berth with a unanimous decision over Mamuka Usubyan, while Luo advanced with a late rally against Kosuke Takagi at ONE SAMURAI 2.
The tournament’s other semifinal pits Masaaki Noiri against Mohammad Siasarani, with the winner earning a guaranteed title shot. Noiri, a former ONE Interim Featherweight Kickboxing World Champion, avenged an earlier loss with a first-round knockout of Liu Mengyang. Siasarani delivered a highlight-reel head kick finish in his 10th promotional victory, setting up a semifinal clash with high stakes and guaranteed entertainment.
