Inoue vs Nakatani Set for May 2 at Tokyo Dome in Historic All Japan Title Fight

May 2 Tokyo Dome bout marks Japan’s biggest fight in decades

Naoya Inoue will defend his undisputed super bantamweight championship against Junto Nakatani on May 2 at the Tokyo Dome. The bout brings Japan’s two unbeaten stars together on the sport’s biggest domestic stage.

DAZN Boxing confirmed the matchup, with additional reporting from The Ring’s Mike Coppinger. The event will mark the first major boxing card at the 55,000 seat Tokyo Dome since 2003 and is already being positioned as one of the most significant fights in Japanese history.

Inoue will enter the fight unbeaten and fully established as one of the sport’s elite. The 32 year old four division champion holds the Ring, IBF, WBA, WBC and WBO titles at 122 pounds and is ranked No. 2 on The Ring pound for pound list. His professional record stands at 32-0 with 27 knockouts, and he has stopped most of the top names placed in front of him over the past five years.

He was active throughout 2025, going 4-0 with victories over Kim Ye-joon, Ramon Cardenas, Murodjon Akhmadaliev and Alan Picasso. The Akhmadaliev win in particular removed one of the last serious threats in the division and strengthened Inoue’s grip on the championship picture.

Nakatani enters as an undefeated former world champion who has climbed steadily through the weight classes. He previously unified belts at bantamweight before moving to 122 pounds. In December, he made his super bantamweight debut on The Ring V Night of the Samurai card, earning a unanimous decision over Sebastian Hernandez in a fight that generated debate over the scoring.

Now 32-0 with 24 knockouts, Nakatani is ranked No. 7 on The Ring pound for pound list. His length, power and calm temperament have made him one of the most respected fighters in Japan, and this fight gives him a direct path to undisputed status.

An all Japan showdown of this magnitude is rare. Both enter unbeaten and ranked among the world’s elite, each carrying real knockout power. Both are ranked among the best in the world. Both carry genuine knockout threat. That combination has fueled anticipation that the Tokyo Dome could reach or approach capacity for a domestic boxing event built around two active champions.

Beyond titles and rankings, the fight carries national weight. Inoue has become a global star, but this bout places him opposite a countryman who has earned his own following and credibility. For Nakatani, it is the chance to step directly into the center of the sport’s spotlight against the man widely viewed as Japan’s standard bearer.

May 2 in Tokyo now belongs to this matchup. Inoue’s dominance has defined the division for years. Nakatani believes he is ready to change that, and there is no bigger stage in Japan to try.
