Boxing Undisputed Champions Stay With Inoue After Tokyo Win
Naoya Inoue won a clear unanimous decision over Junto Nakatani on May 2, 2026, at Tokyo Dome to hold his Boxing Undisputed Champions titles. The win keeps Inoue alone at the top among super-bantamweights and ends Nakatani’s 32-fight unbeaten run.
Inoue mixed thudding power with sharp counters to outwork a brave former three-weight king. The cards pushed Inoue’s record to 28-0 and dropped Nakatani for the first loss of his pro career.
Division Context and Trends
Super-bantamweight has been a busy lane where titles hop often as contenders chase sanctioning fees and ranking points. Over the past 18 months, the belt changed hands four times while Inoue merged the WBA, WBC, IBF and WBO crowns to become one of the sport’s rare active Boxing Undisputed Champions (Sky Sports). Promoters lean on Japanese stars to fuel gates, and local heroes keep seats full and ratings high in prime time. Stability was hard to find until Inoue locked up all four straps and began to defend them against top-ranked mandatory challengers.
Fight Details and Stats
Inoue held his super-bantamweight world titles with wide scores over Junto Nakatani, who suffered his first career loss after 32 bouts (Sky Sports). The Monster took volume and fired back with precision to win rounds while 55,000 fans watched the biggest Japanese boxing show in years. Tape shows Inoue’s lead left hook and uppercut combos broke Nakatani’s pace early and forced the challenger into survival mode by the midpoint. Judges saw it clearly, with two scorecards at 118-110 and one at 119-109 in favor of the unifying champ.
Tokyo Dome was packed with 55,000 fans, one of the largest live crowds for a Japanese card this decade (Sky Sports). Inoue landed power at a high clip and cut off the ring with discipline that few peers can match. One telling detail: the champion faced little real danger after the early rounds, a sign of how he has reset the 122-pound class.
What Comes Next
Inoue’s latest defense locks his name among the top pound-for-pound fighters and keeps the undisputed super-bantamweight titles in one corner while the division resets around him. Mandatory challengers will line up, but the sanctioning bodies are expected to allow a voluntary defense before year’s end to maximize revenue and exposure. The numbers suggest that until a fighter dethrones Inoue at 122 pounds, title fights below the belt will struggle to draw the gate and broadcast heat that Tokyo produced.
Another voluntary looks likely, with a move-up junior featherweight possibly offered to test Inoue’s power at a higher weight. The front office brass knows the risk of overexposure, but they also see a chance to grow the brand while the champ stays active and sharp. Inoue’s blend of timing and pop remains a high wall for any rival, and his run as one of the sport’s Boxing Undisputed Champions is far from done.
What titles did Inoue hold before this fight?
Inoue came in as the unified WBA, WBC, IBF and WBO super-bantamweight champion. He is a four-weight world champion with past belts at light flyweight, flyweight and bantamweight, making him one of Japan’s most decorated pros (Sky Sports).
How rare is an undisputed champion in modern boxing?
Holding all four major belts at once is rare because of sanctioning fees, mandatory rules and promotional splits. Inoue’s consolidation of the WBA, WBC, IBF and WBO straps at 122 pounds places him in a small group of active fighters to achieve that status, a feat made harder by global scheduling and differing mandatory timelines (Sky Sports).
What did Nakatani’s loss mean for his career record?
Nakatani’s defeat ended his perfect 32-fight record and marked the first loss for the three-weight champion. The setback delays any immediate push for a fourth division title and forces a reassessment of matchups while Inoue continues to defend the undisputed super-bantamweight titles (Sky Sports).
