Kai Asakura arrived in the UFC with a champion’s reputation and two fights later had nothing in the win column. In Macau, back at the weight where he built his name in Japan, he did not leave Cameron Smotherman enough time to turn the night into another difficult lesson.
Asakura knocked Smotherman out with punches at 1:50 of the first round on the UFC Macau main card. The finish gave the former RIZIN bantamweight champion his first UFC victory and brought immediate proof that the move back to 135 pounds was more than a change on the bout sheet.
His UFC start had been unusually hard. Asakura signed with the promotion and went straight into a flyweight title fight with Alexandre Pantoja, losing by submission. A second appearance against Tim Elliott ended the same way. Two bouts, two defeats, both at 125 pounds, and a dangerous question hanging over a fighter who had been a major name before entering the octagon.

Asakura looks at home at bantamweight
Smotherman was the first opponent Asakura faced in the UFC without the flyweight cut attached to the assignment. The difference was visible before the finish. Asakura did not look like a fighter trying to survive the opening exchange or wait for the fight to settle. He pressed forward, held his ground and made Smotherman fight while moving backwards.
The ending came quickly. A right hand forced Smotherman towards the fence, where Asakura kept his feet under him and continued the attack. The left hook that followed dropped the American and closed the contest before the two-minute mark. There was no scramble to escape, no late-round collapse and no time for doubt to creep back into Asakura’s UFC run.
That matters for a fighter who was known in RIZIN for bringing danger at bantamweight. His UFC debut placed him against one of the best flyweights in the world. His second fight kept him in that division. Macau finally returned him to the setting where his speed and power had already made him a champion.
- Asakura defeated Smotherman by first-round knockout in his return to bantamweight.
- The win was his first in the UFC after two submission losses at flyweight.
- He earned a $100,000 Performance of the Night bonus for the finish.
- Smotherman suffered his third straight defeat inside the promotion.
Smotherman gets no room to build
For Smotherman, this was the wrong kind of fight to lose early. He entered needing to change the direction of his UFC run, but Asakura denied him any chance to settle into a boxing match or make the Japanese fighter carry the pressure of his previous results.

Smotherman was pushed to the fence before he could establish a rhythm. Against a fighter returning to a familiar weight class with urgency in every exchange, giving ground immediately proved costly. The finish leaves him on a three-fight skid and turns his next roster step into a difficult question.

The UFC now has a different Asakura
The win does not erase what happened against Pantoja or Elliott. Those fights remain part of Asakura’s UFC record, and future opponents will still look at the grappling problems that stopped him twice. But one night can change the next conversation. Before Macau, he was an imported former champion still searching for his first UFC win. After Macau, he is a bantamweight coming off a clean knockout and a performance bonus.
There is no need to rush him into a title discussion. The 135-pound division has more than enough established contenders and difficult matchups waiting. The useful next step is simpler: give Asakura another serious bantamweight fight and find out whether the Macau version is the one the UFC can expect going forward.
For now, the answer is clear enough. Kai Asakura did not lose his finishing threat on the way from RIZIN to the UFC. He needed the right division and the right moment to show it again. In Macau, Cameron Smotherman stood in front of him for less than two minutes before Asakura finally had his UFC win.
