Superbon Chase Starts In Tokyo
Grigorian vs Luo and Noiri vs Siasarani give ONE SAMURAI 4 a sharp semifinal field. The tournament winner is expected to challenge Superbon.
ONE Championship has set the road toward Superbon's next challenger. At ONE SAMURAI 4 on October 17 inside Tokyo's Ariake Arena, Marat Grigorian meets Luo Chao and Masaaki Noiri faces Mohammad Siasarani in the featherweight kickboxing tournament semifinals.
The stakes are plain: the tournament winner is expected to earn a guaranteed shot at Superbon's ONE featherweight kickboxing title. These semifinals are the first real elimination point in the chase for one of striking's strongest champions. Grigorian brings pressure and experience, Luo brings pace and adjustment, Noiri brings timing, and Siasarani brings knockout danger.
Grigorian meets Luo
Grigorian booked his place on August 7 at The Inner Circle 25. The former GLORY champion controlled Mamuka Usubyan across three rounds, pushed him along the retreat lines and repeatedly made him fight from defense. ONE lists Grigorian at 71-14 with four straight wins on the global stage.
Luo is not the bigger name, but he is not a soft semifinal draw. Against Kosuke Takagi at ONE SAMURAI 2 on August 8, he first had to survive a difficult stretch. In the third round he raised his output, worked through the guard and took the decision. Against Grigorian, that becomes the fight's central question: can Luo move and answer long enough, or will Grigorian's pressure force him into exchanges too early?
Noiri faces Siasarani
Noiri produced the cleanest statement win of the tournament at ONE SAMURAI 2. Against Liu Mengyang, he removed the old head-to-head loss from the conversation and ended the rematch in the first round. The right hand pulled Liu out of position, and the left hook closed the sequence. For the former interim champion, it was not just a loud home performance. It was a precise warning: in Tokyo, mistakes against him get punished.
Siasarani brings the quickest finishing threat in this semifinal field. He stopped Kaito a little over a minute in with a high kick, moved their rivalry to 2-0 and, according to ONE, remains unbeaten in promotional kickboxing. For Noiri, that means he cannot only think about outboxing him. He has to finish his combinations in position. Siasarani does not need many clean moments.
The title path
This field works because each semifinalist would ask Superbon a different question. Grigorian would be a credible pressure test. Noiri would bring the biggest Tokyo stage and a clear comeback story. Luo can bend a tournament with rhythm changes and volume. Siasarani carries the form of a finisher who can put favorites in danger early.
That gives ONE SAMURAI 4 more than two strong standalone matchups. Nadaka is scheduled to defend his atomweight Muay Thai title against Rifdean Masdor, while Jonathan Haggerty meets Hiroki Akimoto for the bantamweight kickboxing belt. Between those title fights, the featherweight tournament decides who from the chasing pack truly gets to move toward Superbon. For ONE, that is the right kind of tournament: not decoration on the card, but a title path with consequences.
