Yuki Yoza did not come to ONE Championship to build toward something. He came to chase one man, one belt, and one defining moment — and on April 29, all three arrive at once.
The former multi-time K-1 Champion challenges ONE Bantamweight Kickboxing World Champion Jonathan “The General” Haggerty at ONE Samurai 1 at Tokyo’s Ariake Arena. From the moment Yoza signed with the world’s largest martial arts organization, Haggerty was the target. Earning the right to face him was a different matter entirely. A flawless 3-0 run capped by a masterful dismantling of flyweight kickboxing king Superlek at ONE 173 made the 28-year-old Team Vasileus standout impossible to overlook. The fight he had always wanted was suddenly the fight he had earned.
Yoza has spent considerable time dissecting the champion, and what he found was a puzzle with very few loose pieces. Haggerty built his legend at flyweight, claiming two-division, two-sport gold before moving up. At ONE 171, he systematically dismantled Wei Rui over five rounds. The performance snapped the Chinese star’s 21-fight winning streak and made clear that the move to bantamweight had only made him more dangerous.
“Since moving up to bantamweight, I feel his already strong technique has been backed up by even greater physicality,” Yoza said. “Each strike carries more weight, and you can feel the pressure in his offense. I think he’s become a threat not just in terms of speed, but in power as well.

The respect is genuine, but it does not come packaged with doubt. Yoza believes that within any near-perfect fighter lies something exploitable. It’s a rhythm, a habit, a fraction of space left unguarded, and he has built his entire preparation around finding it.
“Overall, he’s a well-rounded fighter with very few weaknesses. His punches, kicks, defense, and fight management are all at a high level — and that’s exactly why he has remained champion. That said, the more polished a fighter is, the more there are hidden gaps to exploit. Finding those gaps will be the key theme for me going into this fight.”
For Yoza, Tokyo is not simply a venue. It is a stage he intends to own and a promise made to every fan who has followed him to this point.
“I will win the ONE belt — that’s a promise. It is because of the support of everyone who has stood by me that I am able to stand on this stage today. On April 29th, I will show you what it looks like for a Japanese fighter to become champion. I will become the face of ONE Samurai and lead all of ONE Championship forward!”
