The number that matters most from tonight isn’t 33-0. It’s 115-113.
Naoya “The Monster” Inoue retained his undisputed super bantamweight titles at Tokyo Dome, beating fellow undefeated Japanese southpaw Junto “Big Bang” Nakatani by unanimous decision in what was, without question, the most contested fight of Inoue’s career at 122 lbs. The scorecards — 116-112, 115-113, 116-112 — confirm what anyone watching could see: this was not a Monster blowout. This was a 12-round war decided by margins so tight that one judge couldn’t separate them by more than two rounds.

Before tonight, Naoya Inoue’s last three points victories at super bantamweight averaged out to something close to 118-110 per judge. He beat David Picasso in December 2025 with cards of 119-109, 120-108, and 117-111. He outpointed the unified Murodjon Akhmadaliev in September 2025: 118-110, 117-111, 118-110. These are comfortable, sometimes dominant verdicts against credible opponents.
Then Nakatani walked into his life, and the average score dropped to 115.7-112.3. One judge — the closest of the three — had it 115-113: Naoya winning seven rounds, Nakatani winning five. In a 12-round title fight, winning five rounds against an undefeated pound-for-pound top-five fighter is an extraordinary achievement. Nakatani didn’t just show up — he imposed himself.
The data tells the story the broadcast couldn’t fully convey: Nakatani pushed Naoya Inoue harder than anyone has in years. The Monster survived. But he had to earn every second of it.
Both men came in at 32-0. Naoya, 32 years old, Orthodox, with 205 career rounds and a decade of elite-level experience. Nakatani, 27 years old, a southpaw with 164 career rounds and a KO ratio built on explosive finishing power.
Nakatani’s career round count — 41 fewer rounds than Naoya going in — told a story of someone who hadn’t been tested over distance as often. But the quality of his fights painted a different picture: his December 2025 win over Sebastian Hernandez included a 115-113 scorecard, suggesting he was already comfortable in close, grinding affairs.
What the southpaw stance gave him was structural. At 5’7” to Naoya’s 5’5”, Nakatani won the height matchup. His reach of 66.9” created awkward angles that didn’t arrive cleanly on the right-handed Orthodox targeting Naoya had refined against so many previous opponents.
The 115-113 scorecard gives us the sharpest lens on how the rounds broke down. The critical shift came through the middle third. Rounds 4 through 8 were contested territory: Nakatani’s southpaw jab kept finding Naoya’s right shoulder and cheek rather than landing flush, but the movement behind it forced Naoya to reset more often than he has in recent fights.
What ultimately separated them was the final third. Naoya’s championship experience — 205 career rounds, deep appearances in elite 12-round fights — was visible from Round 9 onwards. He increased his work rate, shortened his combinations, and started timing Nakatani’s southpaw step. Nakatani, fighting his longest and most demanding night, couldn’t quite sustain the pace that had made him competitive in the middle rounds.
At 27, Nakatani’s 32-1 record still reads as one of the finest in the junior featherweight / super bantamweight division. He went 12 rounds with the best pound-for-pound fighter on the planet, had him wobbling on at least two judges’ cards in the middle rounds, and made the crowd of 50,000 at Tokyo Dome genuinely uncertain about the result until the final bell.
| Fighter | Record | KOs |
|---|---|---|
| Naoya Inoue (W) | 33-0 | 24 |
| Junto Nakatani (L) | 32-1 | 27 |
For Naoya: the undisputed super bantamweight division is largely conquered. The next logical step is either a super fight at featherweight (126 lbs) or a rematch with Nakatani to settle the argument the 115-113 card opened.
