ONE Championship has begun building the card for its return to Tokyo, Japan this November.
ONE 173 is set to take place at the Ariake Arena in Tokyo, Japan on November 16, 2025, and on Monday, promotion officials announced two big fights for the event. In the main event, ONE featherweight Muay Thai champion Superbon will take on interim champ Masaaki Noiri in a title unification bout.
Of note to MMA fans, heavyweight champion Oumar Kane, popularly known as Reug Reug, will face Anatoly Malykhin for the second time. That heavyweight title clash will serve as the night’s co-main event.
Aside from a single fight in ARES FC at the start of his career, Senegal’s Kane (7-1) has spent the entirety of his MMA career with ONE Championship. He holds wins over Alain Ngalani and Marcus “Buchecha” Almeida, the latter of which earned Kane a title fight with Malykhin.
In November of last year, Reug Reug earned a split decision win over Malykhin to claim heavyweight gold at ONE 169. That stripped Malykhin (14-1) of one of his three ONE world championships — he also holds gold at middleweight and light heavyweight, defeating Reinier de Ridder to capture both.
Malykhin defeated UFC veteran Arjan Bhullar to win the promotion’s heavyweight title in 2023.
