Inoue vs. Nasukawa 2: A Rivalry Reopened for the WBC Title

Takuma Inoue and Tenshin Nasukawa share a ring again on Sunday, and this time there’s no novelty, no curiosity factor. Just pressure. Just stakes.

The WBC bantamweight champion defends his belt against the man he already beat once, in a rematch that feels less like a sequel and more like unfinished business at Toyota Arena Tokyo in the Japanese capital.

A Rivalry Reopened

Last November, Takuma Inoue (22-2, 5 KOs) handed Tenshin Nasukawa (8-1, 3 KOs) the first loss of his professional boxing career, edging a hard, competitive fight to claim the vacant WBC bantamweight title. For Nasukawa, the former kickboxing prodigy turned crossover star, it was a jarring introduction to the unforgiving margins of elite boxing.

Inoue, younger brother of pound-for-pound great Naoya Inoue, didn’t sit on that win. He validated it. He turned back Kazuto Ioka in his first defense, tightening his grip on the division and strengthening his own identity away from his brother’s shadow.

Nasukawa took the long way back. He didn’t ask for favors; he fought for his second chance. In April, he stopped former two-division world champion Juan Francisco Estrada in a WBC eliminator, a statement result that dragged him straight back into title contention and forced the sport to take his boxing credentials seriously.

Now they meet again, same weight, same belt, but with very different questions hanging over each man.

Date, Venue, and How to Watch

The rematch takes place Sunday, Sept. 27, at Toyota Arena Tokyo in Tokyo, Japan.

The event is scheduled to begin at 3:30 a.m. ET, with ring walks for Inoue vs. Nasukawa 2 expected at approximately 7 a.m. ET.

In the United States, the full card, including the main event, streams live on DAZN. In Japan, the show airs on Prime Video.

The Odds and the Pressure

The bookmakers still trust the champion.

Takuma Inoue enters as a clear betting favorite, priced around -260 at U.S. sportsbooks to retain his WBC bantamweight title. Nasukawa sits near +200, the underdog again, despite the buzz generated by his win over Estrada.

On paper, the line says the first fight wasn’t a fluke. In reality, rematches have their own rhythm. Nasukawa now knows what 12 rounds at this level feel like. Inoue knows exactly how dangerous a fully adjusted Nasukawa can be.

One man is expected to repeat. The other is desperate to rewrite.

A Card Stacked With Consequences

Sunday’s show in Tokyo is not a one-fight attraction. It’s a statement card loaded with world-level jeopardy.

Former IBF bantamweight champion Ryosuke Nishida (11-1, 2 KOs) faces Sam Goodman (22-1, 8 KOs) for the IBF interim super bantamweight title in a matchup that could reshape the future at 122 pounds. The winner doesn’t just get a belt; he moves into prime position for a potential shot at undisputed champion Naoya Inoue.

That possibility alone adds an edge. Every round will be fought with the specter of Naoya looming over it.

The world-title theme continues with two more high-stakes clashes.

• Undefeated Tomoya Tsuboi (3-0, 2 KOs) meets Ricardo Malajika (17-2, 12 KOs) for the vacant WBC super flyweight championship. It’s a classic contrast: a fast-rising prospect with only three pro fights against a more seasoned puncher with real knockout power and a belt on the line.
• Then comes a collision of unbeatens for the WBO interim strawweight title. Ryusei Matsumoto (8-0, 4 KOs) takes on Russell Acosta (17-0, 13 KOs), a fight that promises clean records, sharp technique, and the kind of tension that comes when neither man has ever had to walk back to the dressing room second.

Tokyo Under the Lights

So it all funnels back to the main event.

Inoue, the champion who wants to prove he’s more than Naoya’s brother and more than a one-time winner over Nasukawa. Nasukawa, the crossover star trying to prove he’s not just visiting boxing, but belongs at its summit.

One already owns the belt. The other has already felt what it’s like to watch it being wrapped around someone else’s waist.

On Sunday in Tokyo, they run it back. Only one of them walks away with closure.
