Ten months ago, Takuma Inoue controlled distance and pace for twelve rounds to hand Tenshin Nasukawa the first defeat of his professional career and claim the vacant WBC bantamweight title. Scorecards of 117-111 and 116-112 told the story clearly: Nasukawa ran out of answers in the second half. Now Japan’s most compelling rivalry gets a second chapter, live from Toyota Arena in Tokyo on Sunday, September 27.
The rematch carries real weight. Nasukawa didn’t take a tune-up fight after the loss — he stopped former two-division world champion Juan Francisco Estrada in nine rounds in April, winning a WBC final eliminator and converting that mandatory status into this title shot. Inoue, meanwhile, knocked down legendary Kazuto Ioka twice en route to a wide May decision, making his first successful title defence. Both men walk in sharper than they were last November.

Takuma Inoue (22-2, 5 KOs) is the younger brother of undisputed super bantamweight champion Naoya Inoue, a distinction that has followed him throughout his career but has never fully defined him. The 30-year-old from Yokohama has been a world champion twice across different titles, and his story includes the resilience to bounce back from a knockout-pace loss to Seiya Tsutsumi in October 2024 — a defeat that cost him his WBA belt — and return twelve months later to outpoint Nasukawa and reclaim a major title.
Inoue is an orthodox fighter standing 5’5” (164cm) with a 64.2-inch reach. With 227 rounds of professional experience since his 2013 debut, his record shows more craft than power — five knockouts from 22 wins is a 22.7% KO rate — but his technical output and accuracy have made him a consistent scorecard winner at the highest level. His Ioka victory was built on two early knockdowns and a relentless volume game across twelve rounds, a performance that positioned him as one of Japan’s elite 118-pounders regardless of family pedigree.
Tenshin Nasukawa (8-1, 3 KOs) entered professional boxing in 2023 after a dominant kickboxing career, and the speed of his development in a new sport has been striking. The 28-year-old southpaw from Japan — trained at Teiken Gym — stands 5’5” (165cm) with a significant reach advantage at 69.3 inches (177cm). That extra 5 centimetres of reach, combined with a southpaw angle and explosive hand speed, makes him a different proposition from most bantamweight challengers.
Before the Inoue loss, Nasukawa had won 53 consecutive fights across kickboxing, MMA, and boxing combined. His only professional boxing defeat arrived when Inoue ground him down over twelve rounds, with Nasukawa’s output and snap visibly declining from round seven onwards. The Estrada fight in April showed whether something had changed: he won every significant exchange against a former two-division world champion and stopped him in the ninth while ahead on all three cards. It was not a soft touch; Estrada had gone ten or twelve rounds with elite fighters throughout his career, and Nasukawa stopped him emphatically.

The experience gap is the headline number: Inoue has fought 227 professional rounds since 2013; Nasukawa’s professional boxing career began three years ago. That gap mattered in November, when the deeper reserve of ring craft allowed Inoue to manage the pace and outlast Nasukawa’s early pressure. Whether Nasukawa has closed it — through the grind of his Estrada fight plus deliberate preparation — is the central question on September 27.
The first fight established Inoue’s template: use footwork to control distance, force Nasukawa to reach, and pile up punches when the reach differential closes. Nasukawa’s 69.3-inch reach is notable for 118 pounds but effectively neutralised when Inoue gets on the inside, where his compact punching mechanics work well. Nasukawa wins the exchanges in the pocket if he can generate his pop at speed; Inoue wins if he dictates range.
The southpaw angle is a genuine tactical factor. Inoue is a veteran of twelve-round decision fights but has less specific experience against quality southpaws at world-title pace. Nasukawa’s left hand, particularly his jab, sets up the right cross — and if his stamina holds past round six, his power shot ratio should be higher in the second meeting with improved conditioning.
Inoue’s edge is volume and duration. He has fought over 200 rounds more than Nasukawa in professional boxing, and he showed against Tsutsumi that he can absorb adversity and adjust. He also showed against Ioka that he can produce a career-best performance with a title on the line. The question is whether Nasukawa — now with one world-level campaign, an eliminator win, and two years of additional ring time — has enough variety in his attack to make Inoue uncomfortable for twelve rounds.
Takuma Inoue must:
Tenshin Nasukawa must:
Per BetUS, Inoue is -210 (implied probability ~68%) and Nasukawa is +170 (implied ~37%). Those odds reflect the comfortable margin in the first fight and Inoue’s consistent track record against Hall-of-Fame-level opposition. A fighter who has beaten Ancajas, Ioka, and beaten the same challenger once already is a reasonable favourite.
The case for Nasukawa narrowing it — or winning — rests on his Estrada performance and the possibility that the first fight accelerated his development more than any tune-up could have. He is younger, he has been active, and he has a clear tactical path: use the reach, stay disciplined, and trust his speed in the middle rounds when Inoue’s output typically dips.
Prediction: Takuma Inoue by majority or unanimous decision. The experience and conditioning gap still favours the champion. Nasukawa should make it closer this time, possibly winning the first half, but Inoue’s ring intelligence across twelve rounds has proved consistently reliable at this level. If Nasukawa’s conditioning has meaningfully improved and he carries his sharpness past round eight, the scorecards tighten. If it hasn’t, Inoue will control the second half as he did in November.
