On September 2, 2026, at Yokohama BUNTAI, in the WBA world minimumweight title bout, division No. 1 contender Takeshi Ishii knocked out No. 2 ranked Wilfredo Mendez in 1 minute 5 seconds of the first round, capturing the title in his first world title challenge. It’s being called the fastest KO ever by a Japanese boxer in a world title fight, with some reports even calling it a case of “surpassing Naoya (Inoue).” On 5ch’s live-thread, discussion dwelt less on the win itself and more on the small stature typical of the minimumweight division and the structural difficulty Japanese boxers face winning at lightweight and above, turning into a long back-and-forth between posts mocking Ishii’s height and weight and posts pushing back against that mockery.

Kinda lacks flair.
If you're Japanese you'd normally expect middleweight.
Middleweight suits Japanese height/weight, and Japan's produced plenty of champions there too.
Saying middleweight suits Japanese guys — Takehara's gonna lose it lol (Akinobu Takehara, a boxing pundit known for hammering on frame/weight-class realities).
The average Japanese frame is bantamweight to featherweight.
The world average frame is lightweight to super lightweight.
Middleweight guys are huge even by global standards.
Why does every boxing thread always have some old guy dying to bring up 'Koropokkuru'?
What the hell is a Koropokkuru? Say it in plain Japanese, man.
This guy never shows up in Ryota Murata or Mikuru Asakura threads.
There are 4+ 'world' sanctioning bodies out there lol.
It's like there being 4 FIFAs, each crowning its own parallel world champion.
That's boxing for you lol.
And on top of that, the WBA is a garbage organization that loves stuffing one division with a Super Champion, a Regular Champion, an Interim Champion, an Emeritus Champion, and who knows how many more.
I bet they'll eventually invent an elementary-schoolers-only Junior Champion, or a 'Nagasaki Champion' for whoever's best in Nagasaki Prefecture.
Below lightweight: 300+ wins
Lightweight and above: 7 wins
Even counting Ishida, it's only 9 wins at lightweight and above.
Doesn't something seem off looking at that?
Guts Ishimatsu (a legendary Japanese lightweight world champion) alone probably accounts for like 6 of those.
So are you saying all cars and bikes should be big, and nobody should ride small or midsize ones? The 'Koropokkuru' spammers clearly aren't thinking this through.
There's a limit to that logic though. Minimumweight has a thinner talent pool than heavyweight, and its technical level lags the heavier divisions too.
Give us a strong Japanese fighter at lightweight or above for once.
Then go do it yourself.
47kg (lol)
He's the best in the world at trading punches within that weight class, isn't he? What exactly is there for you to mock?
But that's the same guy who says the strongest P4P (pound-for-pound) fighter is Fury — a guy who loses to amateurs.
Total newbie. Fury has only ever lost to Usyk.
You probably mean Ngannou.
Calling that a win is downright embarrassing. Getting dropped by an amateur, ending up with a black eye, resorting to elbows and other fouls, and only surviving on a judges' decision — pathetic.
Background and Key Points of This Discussion
The WBA runs its own ranking system that lets multiple champions — “Super,” “Regular,” “Interim,” and “Emeritus” — coexist within a single weight division, and Ishii’s title here is one belt within that structure. Because boxing divisions are split by weight, Japan tends to have a deeper pool of contenders and champions in the lighter divisions, where smaller-framed fighters cluster, while the scarcity of Japanese champions at middleweight and above owes largely to structural differences in body frame. The thread’s recurring claim that smaller fighters have an easier path to a world title shot reflects that structural reality, but there’s no objective metric for comparing skill level across weight classes, so much of the comparison remains impressionistic. It’s also worth noting that a KO time of 1:05 depends heavily on the gap in ability between the two fighters, so it shouldn’t simply be generalized as proof of overall strength.
