Vinny's Corner

Takuma Inoue vs. Tenshin Nasukawa 2 headlines Prime Video Boxing 16 on Sunday, September 27, 2026, at Toyota Arena Tokyo. The WBC bantamweight champion Takuma Inoue makes his second defense against the mandatory challenger in a rematch of their November 2025 title fight.

The first meeting produced a competitive but clear unanimous decision for Inoue (116-112, 116-112, 117-111). Ten months later both men return with extra experience, higher-profile wins, and something to prove.

Breaking Down the Fighters

Takuma Inoue

• Record: 22-2, (5 KOs)
• Age: 30
• Height/Reach: 5’4½”/ 64½ inches
• Stance: Orthodox 
• Hometown: Yokohama

Yokohama’s Ohashi Gym product and younger brother of undisputed super bantamweight king Naoya Inoue. Takuma is a two-time world champion who previously held the WBA bantamweight title. He lost that belt to Seiya Tsutsumi in October 2024, considered retirement during a 13-month layoff, then captured the vacant WBC strap against Nasukawa.

His first defense was a statement: a dominant unanimous decision over four-division legend Kazuto Ioka in May 2026 at Tokyo Dome, during which he scored two knockdowns. Inoue is a high-volume, technically sound boxer who uses a sharp jab, straight right, and body work. He is durable (never stopped) and improves as fights progress. Power is not his calling card, but his ring IQ and stamina are.

Tenshin Nasukawa

• Record: 8-1, (3 KOs)
• Age: 28
• Height/Reach: 5’5” / 69½” inches
• Stance: Southpaw 
• Hometown: Matsudo

The former kickboxing phenomenon (long undefeated run in that sport) turned pro boxer in 2023. He rattled off seven straight wins, including decisions over former WBO champion Jason Moloney and Victor Santillan, before the first Inoue loss. In April 2026 he earned mandatory status with a ninth-round retirement stoppage of two-division champion Juan Francisco Estrada.

Nasukawa brings elite movement, feints, a dangerous southpaw left hand, and unorthodox timing from his kickboxing background. He has a significant reach advantage and looks to fight at range. The Estrada win showed improved pressure and finishing ability against a faded but still skilled veteran. His only boxing loss remains the first Inoue fight.

Fight Analysis

The first fight followed a familiar script for many crossover stars. Nasukawa started brightly, using distance, feints, and his left hand to take the opening rounds. Inoue was credited with a slip rather than a knockdown in the second. After four rounds the fight was even on the open scorecards. From the middle rounds onward Inoue’s jab, straight right, body work, and superior positioning took over. Nasukawa needed a late surge or knockdowns after the eighth-round scores were announced; he produced some fireworks in the 11th but could not close the gap.

Key matchup questions for the rematch:

• Can Nasukawa stay at his preferred range longer and avoid being walked down?
• Has Inoue’s work against Ioka (early knockdowns and control) made him even more composed under pressure?
• Will Nasukawa’s extra power and finishing instinct from the Estrada fight change the later rounds?
• Does Inoue’s experience in 12-round championship fights still outweigh Nasukawa’s athletic advantages?

Inoue has spoken of wanting a more decisive result this time and even mentioned a knockout. Nasukawa has declared he will “knock him out.” Both camps have been public in training. The champion’s edge in rounds boxed and championship experience remains significant, but Nasukawa is a more complete boxer than he was 10 months ago. The reach and southpaw stance still give the challenger a path if he can keep the fight on the outside and make Inoue miss.

Betting markets list Inoue as a moderate favorite (around 4/9), with Nasukawa in the 2/1 to 11/5 range. Community sentiment also leans toward the champion.

Official Pick

Takuma Inoue by unanimous decision.

The first fight showed that Inoue’s fundamentals, timing, and ability to adjust mid-fight are the difference at this level. He has looked sharper since, particularly in the Ioka performance. Nasukawa will likely have his moments early and may make it closer or more exciting, but over 12 rounds the champion’s experience and consistency should carry the scorecards again. A late stoppage is possible if Nasukawa fades, but the safer and more likely outcome is another points win for Inoue.
