Could a Kendo Club Member with a Wooden Sword Beat a Heavyweight Boxer? 5ch Erupts in Debate

From our other sites

The story

A thread has caught fire on 5ch after a post claiming, “If a kendo club member picked up a wooden sword, he could even beat a heavyweight pro boxer.” One camp argued the kendo fighter has the edge if he can endure long enough to close the distance, using the wooden sword’s reach and lethality as his weapon; the other countered that a heavyweight boxer’s punch would end things long before that. Commenters cited the legend of Miyamoto Musashi and Sasaki Kojiro’s duel at Ganryu Island, as well as Tenshin Nasukawa’s swift KO loss to Floyd Mayweather, as the debate split over which matters more in a fight: “distance control” or “the weight of a single blow.”

Sounds like a walk in the park, apparently

One solid thrust from a wooden sword and it's over.
Even a bamboo shinai is dangerous enough that thrusting attacks are banned for anyone below high school age.

So high schoolers are just fine dying from a thrust, huh

And if it misses, he eats a Mike Tyson straight, gets sent flying several meters, and it's game over with a fractured skull

You guys are seriously underestimating the wooden sword (bokuto).
Kendo club uses a bamboo shinai, remember.
A shinai won't kill you, but a solid wooden sword definitely can.
When Miyamoto Musashi faced Sasaki Kojiro at Ganryu Island, Kojiro used a real blade, but Musashi still killed him with a wooden sword.

Re: #58
Is that historical account even accurate?
403AnonymousAug 30, 2026 13:57
Re: #58
Then again, one theory about Ganryu Island says Kojiro was already an old man by then, and Musashi actually brought disciples along to gang up and beat him down

If a baseball player beans you with a hardball from 10 meters out, nobody's getting back up.
Wherever it hits, "ouch" doesn't even begin to cover it.
A baseball player who can nail you at over 100 km/h with real accuracy might honestly be the strongest of all.

Re: #85
By that logic, Shintaro Fujinami, who throws 160 km/h fastballs, would be the strongest guy alive
96AnonymousAug 30, 2026 10:03
Re: #91
He can't hit left-handed batters though (a running joke about Fujinami's notoriously wild control)

Throwing rocks is a legitimate foot-soldier tactic

No but seriously, a guy with a wooden sword is helpless unless he's within striking range.
A baseball player with a ball can keep firing away, whether it's 5 meters or 10.
In a real fight with balls or rocks flying, a baseball player used to that kind of thing is basically unbeatable.
Even a 2-meter-tall wrestler would go down.

In Shin Hissatsu Shiokinin (a Japanese period drama), Fumio Fujimura hit it right back

Re: #101
Let's say a baseball player and a kendo fighter face off in a duel 20 meters apart.
The kendo fighter holds the wooden sword vertically in front of his body for defense and charges straight in.
Even someone slow can cover 20 meters and close the distance in 5-6 seconds.
Can the baseball player really get off 5 pitches in that time?
And this is a guy who already struggles to hit the target in a strikeout contest — how's he supposed to land a fatal shot on someone charging at him with his vitals covered?
The instant the kendo fighter closes the gap, it's one strike to the skull and the baseball player's dead.

The reach is completely different, so if the opponent steps in, just use footwork and the sword tip to counter into the face, throat, or solar plexus.
Being able to answer while backing away is the biggest advantage.
If he's slowly closing in, just keep landing fast thrusts to the face and it's a landslide win.

Re: #136
I don't know how good you think you are, but do you seriously believe kendo footwork can match a pro boxer's?
163AnonymousAug 30, 2026 10:51
Re: #147
It's the other way around — kendo footwork is insanely fast

Re: #147
Boxer footwork that gets stomped flat in one step by a well-built athlete
193AnonymousAug 30, 2026 11:45
Breaking the wooden sword, easily closing the distance, catching a live blade bare-handed like it's nothing — do you seriously think any of that is easy? (lol)
196AnonymousAug 30, 2026 11:47
Re: #193
What if he charges in accepting he'll eat one hit?
If you can't knock him out cold with that single blow, you lose
200AnonymousAug 30, 2026 11:50
Re: #196
Might work against a weak kendo club member
655AnonymousAug 30, 2026 16:12
Re: #196
You can land combo strikes while backing away, you know

Heavyweights are basically wearing armor made of muscle.
If you can't take him out in one hit, you'll be the one knocked out in seconds
205AnonymousAug 30, 2026 11:52
Re: #201
No matter how much muscle you pack on, pain is pain — you can't just tough that out
275AnonymousAug 30, 2026 12:43
Tenshin Nasukawa, who was unbeatable against Japanese opponents, still got knocked out cold after taking just a few light shots from Mayweather, a boxer fighting up a weight class.
And that's a Mayweather who'd already retired and mostly fought around welterweight (lol).
If a kendo club kid took a punch from an active heavyweight boxer, he'd go flying, wooden sword and all.

A boxer with no protective gear who's only good for throwing punches probably can't pull it off

346AnonymousAug 30, 2026 13:33
Apparently there were tons of guys out there picking fights even with prime Mike Tyson, telling him "I'm tougher than you."
Makes you wonder if boxers just have a reputation for being bad at real fighting?

Apparently when the actor Kaneko made his combat-sports debut, he specifically requested a boxer-type opponent

You really think a student kendo club member could stand up to this guy? (lol)
I doubt he could even keep his cool the first time this thing comes charging at him up close.
This is closer to fighting a wild animal than a human.

Re: #367
He's not tough enough to shatter the tip of a wooden sword charging straight at him
430AnonymousAug 30, 2026 14:05
The reason gangs favor metal bats and iron pipes is that wooden swords aren't actually that practical in real fights.
Anyone in this thread fantasizing about wooden swords clearly hasn't seen the real world
435AnonymousAug 30, 2026 14:06
Re: #430
There's no such thing as gangs using metal bats
440AnonymousAug 30, 2026 14:08
Re: #430
It's simply that there aren't wooden swords lying around, and metal is harder than wood anyway
453AnonymousAug 30, 2026 14:13
Re: #430
The reason the Kanto Rengo (a real-life delinquent gang) killed people with bats as a group is this:
if you're caught carrying a wooden sword without belonging to a kendo club, you could be charged with a firearms-and-swords violation, and the sentence is harsher.
With a bat, you can claim you were just about to play some casual baseball.
Plus, attacking as a group makes it unclear who actually landed the killing blow.
472AnonymousAug 30, 2026 14:19
At the very least, boxing skills alone make it tough to beat a kendo fighter
479AnonymousAug 30, 2026 14:21
Re: #472
If he starts grabbing and clinching, he's got a shot, but
that's not boxing anymore.
Once you fight outside boxing rules, you're not a boxer anymore, just a big guy

What kind of twisted logic is that (lol)

In an actual boxing match, the opponent is doing boxing too, you know

Background and key points of this debate

This kind of “who would win in a mixed-discipline fight” thread is a 5ch staple, and here the difference between a solid wooden sword (bokuto) and a bamboo shinai became the starting point. Indeed, thrusting attacks with a shinai are considered dangerous enough to be banned for anyone below high school age, and a wooden sword is said to be even more lethal — while the boxer’s lifeline is how many punches he can land in the few seconds it takes his opponent to close the distance. The Nasukawa-Mayweather bout cited in the thread was a 2018 exhibition match rather than an official title fight, which is worth noting. Likewise, the Ganryu Island legend of Miyamoto Musashi killing Sasaki Kojiro with a wooden sword has competing historical accounts — including a theory that Musashi ambushed Kojiro with the help of his disciples — and isn’t settled fact. The thread also brings up a real group, the Kanto Rengo, and their choice of weapons, but this is general commentary drawing on past incidents rather than a reference to any specific act or victim. Overall, opinions remain split across three axes — “distance,” “reaction speed,” and “the weight of a single blow” — with no resolution in sight.
