Daisuke Hori, a self-proclaimed “short sleeper” who claims to have slept just 30 minutes a day for 17 years, is running an endurance livestream apparently meant to prove it — and by day three, he looks visibly wrecked. The stream has caught him quietly closing his eyes off-camera, talking less and less, and struggling to even get through basic workouts, sparking a mix of genuine concern and dark amusement on 5ch. While the stream’s popularity — peaking at over 60,000 concurrent viewers — became a talking point in itself, plenty of posters remain skeptical that the 30-minute sleep claim is even true, splitting the thread between worry over his health and doubt over his story.
This guy might genuinely be doing all this stuff — teeth whitening, massages — just for an excuse to close his eyes for a bit

This is probably just his normal everyday life
16AnonymousSep 13, 2026 11:19
Once this stunt's over he's probably gonna get the best sleep of his life
17AnonymousSep 13, 2026 11:19
Lol he's clearly lost all his energy compared to day one
18AnonymousSep 13, 2026 11:19
He's probably about to keel over from caffeine poisoning from chugging so many energy drinks and caffeine tablets like Minmin Dakai (a popular Japanese anti-sleep pill)
20AnonymousSep 13, 2026 11:19
He can't even properly work out anymore
22AnonymousSep 13, 2026 11:20
Just checked in and lol, he looks exactly like my kid right before nap time — wants to play but is too sleepy to
25AnonymousSep 13, 2026 11:20
Bet he'd perk right up if someone threw a big Super Chat at him
26AnonymousSep 13, 2026 11:20
Only 36 hours in — any of the NanJ posters (regulars from 5ch's laid-back sports/chat board) who were saying "this guy's the real deal" still breathing?
27AnonymousSep 13, 2026 11:21
Lol he's talking way less than he was on day one's stream
30AnonymousSep 13, 2026 11:21
Bet the ending's gonna be "sorry everyone, I was actually sleeping the whole time!" as the punchline
31AnonymousSep 13, 2026 11:21
Lol he's just sitting on the bench not training at all
Real inefficient
33AnonymousSep 13, 2026 11:22
Feels like he's gonna do irreversible damage to himself
He's probably got enough money to live comfortably forever if he just invested it sensibly — why risk his life over something this dumb
35AnonymousSep 13, 2026 11:22
If it's really his everyday routine then doing it regularly shouldn't be a problem
36AnonymousSep 13, 2026 11:22
Just watched — lol he's straight up saying it's rough
38AnonymousSep 13, 2026 11:22
Why set the bar at such a crazy 30 minutes?
Even 5 hours a day would already count as a short sleeper, and 3 hours would already have people going "does someone like that really exist?"
30 minutes is obviously a lie
Even people who claim to average 5 hours a day are probably sneaking in naps
39AnonymousSep 13, 2026 11:22
Weird, considering it's supposedly been his daily routine for 17 years?
41AnonymousSep 13, 2026 11:22
Why did this guy start calling himself a short sleeper in the first place
All he's doing is livestreaming, in real time, proof of how unhealthy you get when you don't sleep
45AnonymousSep 13, 2026 11:23
64,000 concurrent viewers lmaooooooooooooooooooo
46AnonymousSep 13, 2026 11:23
The fact that this guy's gone viral and has tons of people watching means he's already making bank, which is honestly confusing
47AnonymousSep 13, 2026 11:23
Don't go calling him just some NEET (a term for someone Not in Education, Employment, or Training) who's trying his best
48AnonymousSep 13, 2026 11:24
Just let him off the hook already
It'd genuinely suck if he actually died
62AnonymousSep 13, 2026 11:25
Re: #48
There's nothing to "let off the hook" — he's just doing this on his own lol
49AnonymousSep 13, 2026 11:24
Is he always in this half-dead state?
50AnonymousSep 13, 2026 11:24
I used to think he was always irritable because he only sleeps 30 minutes a day, but maybe he's actually been sleeping fine this whole time, and the irritability was really just fear of his story being exposed as a lie
51AnonymousSep 13, 2026 11:24
Lol the thumbnail makes him look super tough but in the actual video he looks like he's dying
52AnonymousSep 13, 2026 11:24
Pulling in this many concurrent viewers means he wins no matter how this turns out
54AnonymousSep 13, 2026 11:24
Lol looked away for a second and he teleported to right in front of the kitchen
56AnonymousSep 13, 2026 11:24
Lmao he's been panting nonstop this whole time
58AnonymousSep 13, 2026 11:25
Just going about his normal day earning this much per minute — he's probably out-earning Shohei Ohtani
68AnonymousSep 13, 2026 11:26
Re: #58
No way — Ohtani's side income alone is something like 19.5 billion yen a year
59AnonymousSep 13, 2026 11:25
Re: #44
Whatever he's selling, nobody in their right mind would want to buy it from a guy like this anymore
69AnonymousSep 13, 2026 11:26
Re: #59
And yet they exist
Idiots out there paying this guy money every month
Background and Key Points of This Discussion
Daisuke Hori has publicly claimed to be a “short sleeper” who has slept just 30 minutes a day for 17 years, and this thread covers day three of an endurance livestream apparently meant to demonstrate that lifestyle. As his eye-closing and reduced talking became more noticeable than on day one, viewers have simultaneously voiced concern for his health and skepticism toward the sleep claim itself. That said, it’s worth noting that nothing in the stream or the thread confirms he has retracted the claim or that it has been proven false — accusations like “scam” or “selling info products” remain speculation on an anonymous message board. As the figure of over 60,000 concurrent viewers suggests, much of the audience seems less interested in whether the claim is true than in the thrill of wondering whether he’s actually going to collapse.
