- Inoue had to dig deeper than ever before — and still found the answers in the championship rounds against a 32-0 Nakatani
- Beating a peak, undefeated, division-mate at the Tokyo Dome is a P4P credential nobody else on the list can match
- Terence Crawford retired, Usyk faces a kickboxer next — Inoue is the only top-three P4P name in a competitive fight
Right then — twenty-four hours on. The Tokyo Dome roof has stopped vibrating, the scorecards have been studied to death, and the noise has settled into something like consensus. Naoya Inoue's 116-112, 115-113, 116-112 decision over Junto Nakatani wasn't a blow-out. It wasn't an early stoppage. It was a proper twelve-round fight where the Monster got pushed harder than he's ever been pushed and still walked out with the belts and the W. And here's the bit that matters: that performance, in that fight, against that opponent, only strengthens his case as the best pound-for-pound fighter in the world.
Make no mistake, before Saturday night the lazy take on Inoue's P4P credentials was that he hadn't been tested. He'd flattened everyone in front of him. Luis Nery hit the deck four times. Stephen Fulton was demolished in eight. TJ Doheny was halted on the body. The complaint went: when does he share a ring with a real one? Well, he shared a ring with a real one. Nakatani came in 32-0, the bigger, longer man, with the left hand from hell and a stoppage rate that would make most contenders blush. And he tested Inoue properly — won rounds, hurt him at points, walked him onto the back foot in the middle of the fight. That's the kind of test the Monster needed for his P4P case. Now he's had it.
What Beating A Peak Nakatani Actually Means
Let's not beat around the bush. There is no fighter on any sensible pound-for-pound list right now who has beaten an opponent of Nakatani's calibre in the last twelve months. Terence Crawford retired after the Canelo win. Oleksandr Usyk is fighting a kickboxer in three weeks. Dmitry Bivol is contemplating his future. Jaron Ennis hasn't fought a top-five welterweight since stepping up. Canelo Alvarez's next bout is against a man who became a champion by Crawford retiring. The pound-for-pound conversation is suddenly very thin at the very top, and Inoue just walked into the only available oxygen.
Beating a 32-0 division-mate at the Tokyo Dome is a credential. Beating him in the second-toughest fight of his life — Nonito Donaire 1 will always be the toughest — is a credential. Beating him via an honest unanimous decision rather than a polite stoppage is a credential. Brilliant fighters do not always get to decorate their wins with knockouts. Sometimes they have to win rounds. Inoue won the rounds that needed winning.
The Championship Rounds Tell The Story
Look at how the fight actually played out. Inoue built a lead in the opening five. Nakatani found his footing in the middle and won three or four on the bounce — that round eight in particular was a proper Nakatani round, the kind that gets your name on the headlines if it carries over to the eleventh. The Monster could have wobbled. Champions don't wobble. The accidental clash of heads in round ten cut Nakatani and shifted the rhythm, and Inoue did exactly what proper P4P fighters do — he sensed the shift, came forward, and stole the eleventh and twelfth on every card. The body work in eleven was clinic-level. The combinations in twelve were the close-out.
That's championship level. That's why he's pound-for-pound number one. He didn't get his way for forty-five minutes and he still won the fight. If you know, you know — that's the difference between a great fighter and a P4P-tier one.
Where The List Sits Now
The P4P top three after Saturday night, the way Boxing Lookout sees it: Inoue at the top, Usyk at two, Bivol at three. Usyk faces Rico Verhoeven on May 23 in Egypt — a kickboxer with one professional boxing fight, twelve years ago. Whatever your view of the matchmaking, it's not a P4P-needle-mover. Bivol's been quiet. The vacuum at the top is being filled by the Monster on his own.
What does that mean practically? It means when boxing media sit down at the end of 2026 to vote on Fighter of the Year, Inoue has already submitted the case. A win in his next fight — whether that's the featherweight move to chase Rafael Espinoza's WBO belt or a stay at 122 to clean up the rest — and he's the runaway favourite. The Tokyo Dome win is the foundation. Anything else is decoration.
The One Critique And Why It's Wrong
The pushback you'll hear all week is the standard one — that Inoue looked human in the middle rounds, that he was outworked at points, that this was the closest he's ever looked to losing. All of which is true. None of which damages the case. Brilliant fighters look human against other brilliant fighters. That's the entire point. If he'd walked through Nakatani in three the way he walked through Fulton, the conversation would still be the same one we'd been having for three years — yeah, but who's actually tested him? Now that question's gone.
Right then — Inoue 33-0, undisputed at 122, pound-for-pound number one. The Monster just won the hardest fight of his life and reminded everyone what it means to be the best fighter in the world. Brilliant night for the sport. Class champion at the top of it. And now we wait to see whether the next move is up to featherweight or another defence at 122. Either way, the P4P throne sits in Tokyo.
