Daisuke Hori Drops His ‘Short Sleeper’ Label, Sparks Debate With ‘Sleep However Long You Want’ Comment

From our other sites

The story

Daisuke Hori built a name for himself as a self-proclaimed “short sleeper,” running courses and seminars based on his own sleep theories. This time, word that he’d dropped that label and declared “sleep time is free” made the rounds on 5ch and drew a wave of reactions. Commenters were split: some saw the timing of his pivot as setup for pushing new products or sponsorship deals, others demanded explanations and refunds for people who’d paid for his pricey courses, and a few actually praised the change in direction.

Called it.
I predicted he'd pivot to cashing in on "sleep is important" content next.
This is just the setup for that.

Re: #3
From "sleep is harmful!" to "life is sleep!"
Then he's got a plan to cash in on bedding sponsorships and the like.
5AnonymousSep 17, 2026 17:00
"Know-how for controlling sleep and drowsiness" 👈
7AnonymousSep 17, 2026 17:01
Weak move.
If that's the case, refund everyone who paid for his past programs.
9AnonymousSep 17, 2026 17:03
He's basically saying the same thing as Captain Roger (the "freedom" line from One Piece).
11AnonymousSep 17, 2026 17:04
Just as expected — he's still planning to keep selling his product.
12AnonymousSep 17, 2026 17:04
Well, reflecting and changing course is a good thing.
But he still needs to apologize and pay damages to everyone he's scammed so far.
17AnonymousSep 17, 2026 17:06
Re: #12
He's not actually reflecting on anything — he'd already decided to drop the "30 minutes" claim before the stream even started.
Using controversy to build buzz and then pivoting to a new claim was the plan from day one.
13AnonymousSep 17, 2026 17:04
Everyone naps outside their normal sleep hours anyway — he didn't need to make such an extreme claim.
He only says such over-the-top stuff because he's lying.
18AnonymousSep 17, 2026 17:06
Re: #13
Actually, this guy's been saying all along it's "30 minutes of core sleep plus 3 naps."
So napping is part of his "normal routine."
The "3 naps" part is just being conveniently cut out.
Not that I'm defending the guy or anything.
14AnonymousSep 17, 2026 17:05
Sounds like one of those "I only realized after actually trying it" moments.
19AnonymousSep 17, 2026 17:07
People who were all hyped over Daisuke Hori seem like easy marks for a scam.
22AnonymousSep 17, 2026 17:08
Maybe there's a mastermind pulling the strings behind him, like with Yutabon (a controversial child YouTuber often suspected of having an adult handler).
23AnonymousSep 17, 2026 17:08
Did he take a power nap today, I wonder?
24AnonymousSep 17, 2026 17:08
Re: #18
What's even the difference between "core sleep" and a "nap" in the first place…
It can't be the same as a normal person's nap.
32AnonymousSep 17, 2026 17:10
Re: #24
Honestly, it doesn't really make sense.
But he's always had that kind of loophole built in.
Hori's pretty sharp when it comes to covering himself.
26AnonymousSep 17, 2026 17:09
Getting way too full of himself — someone should just sue him for fraud already.
27AnonymousSep 17, 2026 17:09
How do you think the people who paid about 170,000 yen for his two-month program feel right now?
42AnonymousSep 17, 2026 17:17
Good for him.
I think he did well.
Though I don't know how the seminar attendees feel about it.
45AnonymousSep 17, 2026 17:18
Re: #42
It's probably like a religion at this point, so it likely won't be fatal for him.
Though a few people might actually file lawsuits.
52AnonymousSep 17, 2026 17:21
Setting this guy aside, I do think sleep time is wasted time in life.
I only sleep 3 hours myself.
54AnonymousSep 17, 2026 17:25
Re: #52
A professor from the University of Tsukuba says sleep is important, so go to sleep, idiot.
He's a legit professor who's won the Lasker Award.
53AnonymousSep 17, 2026 17:23
For pillow and blanket ads, there's no one better suited right now than this guy.
Both the promotional effect and the persuasive power would be off the charts.
57AnonymousSep 17, 2026 17:27
Re: #53
The question is whether any company would actually hire someone with his personality — the type who picks fights with collab partners and forces them into apologies like "sorry for letting you sleep."
91AnonymousSep 17, 2026 17:49
Re: #53
But would anyone actually want to use the same bedding as this guy?
Nobody's buying that egg-shaped chair of his anymore, right?
60AnonymousSep 17, 2026 17:29
It's not good that scams like this keep getting away with it.
64AnonymousSep 17, 2026 17:31
Re: #60
We don't actually know if it's fraud, so don't go posting that anywhere but here.
71AnonymousSep 17, 2026 17:36
Re: #64
We just don't know if it legally counts as fraud — but he lied and took huge sums of money from people, so a scam is a scam.
84AnonymousSep 17, 2026 17:44
Re: #71
Well, I don't really know.
I'm not defending him or anything, so it doesn't bother me, but Hori seems like the type who'd actually go after people for damages, so that's just a heads-up.
Though he's probably not reading this board anyway.
86AnonymousSep 17, 2026 17:45
Refunding the people who took his courses is where the starting line should be.
Though I don't think he needs to refund the Super Chats.
92AnonymousSep 17, 2026 17:49
Re: #86
Yeah, that — plus a proper apology for the fraud — needs to come first.
90AnonymousSep 17, 2026 17:48
He's probably wrapping this up because he's made enough to go back to the investment world again.
96AnonymousSep 17, 2026 17:51
Re: #90
I wonder if he'll come crawling back if it doesn't work out.
98AnonymousSep 17, 2026 17:52
Not sure he'll get another chance, but I wonder what he'll say if he's ever invited onto media again.
Then again, I don't even know what title he'd go on as at this point.
102AnonymousSep 17, 2026 17:54
Re: #98
Probably "U.S. Congressional Legislative Researcher" or something like that.

Background and Key Points of the Debate

Daisuke Hori is known for building courses and seminars around a “short sleeper” theory centered on claims like “30 minutes of sleep a day,” and some posters in the thread say tuition for his programs ran into the hundreds of thousands of yen. It’s not unusual for self-help influencers pushing homegrown health theories to later revise their headline claims, and the timing of such revisions tends to get linked to the possibility of new sponsorship deals or promotions. Opinions in the thread split over whether to view his explanation of “core sleep plus naps” as an after-the-fact excuse, or to take the shift in stance itself as an honest course correction. It should be noted that whether Hori’s course content or statements legally amount to fraud is a matter for the courts to decide, and speculation or judgments made on 5ch don’t necessarily reflect fact.
