Streamer Daisuke Hori is in the middle of a “24 hours a day, for one week” broadcast, and a new rule allowing “unlimited naps” has become a hot topic on 5ch. Hori has built his brand around being a “short sleeper” who supposedly only needs 30 minutes of sleep, and when the production staff explained that naps, passing out, and microsleeps don’t count as “sleep,” viewers — who already had their doubts — pushed back hard. The thread turned into a nitpicky back-and-forth over where exactly a nap ends and sleep begins, with commenters even comparing it to how little sleep parents of young children get.
Huh, he's got a Chiikawa mug (the popular cute-character franchise).

He had a whole week to plan this out, you'd think he could've come up with a better way to survive it…
6AnonymousSep 10, 2026 19:22
Just leave him alone, in a few more days he'll be nothing but crying and snapping at people anyway.
7AnonymousSep 10, 2026 19:23
Watched the stream — yesterday he clearly didn't get 7 hours of sleep, the eye bags were no joke.
8AnonymousSep 10, 2026 19:23
Honestly the saddest part of all this is the YouTuber who actually attempted the "Daisuke Hori Challenge."
9AnonymousSep 10, 2026 19:24
You need naps? Maybe just… sleep properly?
10AnonymousSep 10, 2026 19:24
Comparing the morning stream to the evening stream, his face looked like a completely different person lol
11AnonymousSep 10, 2026 19:25
Can't be helped, it's a challenge
It's a challenge, after all
12AnonymousSep 10, 2026 19:25
The staff really should just leave him be and let him wake up on day 8 or whatever.
13AnonymousSep 10, 2026 19:26
He's probably going to lose his appetite after this too.
15AnonymousSep 10, 2026 19:27
If he wanted to call himself a short sleeper, he should've just said 3 hours instead.
20AnonymousSep 10, 2026 19:29
Naps don't count as sleep, and microsleeps don't count as sleep either
So even if naps plus microsleeps add up to 8 hours, he's still technically a "short sleeper"?
And any time he's off-camera is just more microsleep and napping, so that's fine too?

Re: #20
Passing out doesn't count as sleep either, apparently.
26AnonymousSep 10, 2026 19:31
Re: #20
If that logic flies, most moms raising kids out there qualify as short sleepers too.
32AnonymousSep 10, 2026 19:34
If naps are genuinely allowed, he's basically undermining everything he's built his career on.
37AnonymousSep 10, 2026 19:36
Re: #32
He only ever said "30 minutes of sleep," didn't he?
Naps, passing out, and microsleeps don't count as sleep, remember?
56AnonymousSep 10, 2026 19:41
A microsleep is only supposed to last a few dozen seconds — snoring while you're out cold isn't a microsleep, come on.
60AnonymousSep 10, 2026 19:42
Re: #56
Even if he's snoring, he's aware he's snoring, so it's a microsleep, apparently.
66AnonymousSep 10, 2026 19:44
His face looks way worse than I expected lol
He's definitely getting more sleep than this on a normal day
69AnonymousSep 10, 2026 19:46
Re: #66
If it were really just 30 minutes, he'd have collapsed ages ago.
75AnonymousSep 10, 2026 19:46
It'd be way too depressing if this ends with him winning a Darwin Award.
80AnonymousSep 10, 2026 19:47
Re: #75
He's got kids, so he's disqualified [Darwin Awards traditionally go to people who remove themselves from the gene pool].
79AnonymousSep 10, 2026 19:47
But honestly, it's kind of admirable that he's genuinely sleep-deprived and looking exhausted, instead of secretly napping off-camera and lying about it.
81AnonymousSep 10, 2026 19:48
Re: #79
Committing fully to the lie would be the truly dedicated move.
86AnonymousSep 10, 2026 19:50
Re: #79
The fact that he's even sleep-deprived at all is suspicious lol
Pretty sure he sleeps more than this normally
92AnonymousSep 10, 2026 19:52
If lying in bed with your eyes closed counts as "meditation" instead of sleep, hitting 30 minutes of "sleep" a day is easy.
94AnonymousSep 10, 2026 19:52
This could all end with a simple "sorry" — so what's actually driving him to keep this up?
95AnonymousSep 10, 2026 19:53
I checked in on the stream now and then whenever I had a spare moment, and no matter the hour he was just doing strength training nonstop, made zero sense
Does this guy even have a job?
105AnonymousSep 10, 2026 19:58
Isn't this guy basically running an awareness campaign for how important sleep is? [i.e., unintentionally proving the opposite of his claim]
109AnonymousSep 10, 2026 20:01
Re: #105
ABEMA [a Japanese streaming platform] just started a show about the importance of sleep, they should do a collab.
110AnonymousSep 10, 2026 20:01
Say what you want, but a full day's actually gone by
Even though he apparently dozed off during a head spa, that's still impressive.
119AnonymousSep 10, 2026 20:02
Re: #110
Making it to around 2 days is basically what a college student pulling an all-nighter could manage anyway.
122AnonymousSep 10, 2026 20:03
Just let the guy sleep already.
125AnonymousSep 10, 2026 20:04
Re: #122
He's the one choosing to do a no-sleep challenge, though.
129AnonymousSep 10, 2026 20:04
Re: #125
What do you mean "challenge"? This is supposed to be his everyday life.
143AnonymousSep 10, 2026 20:09
There's also a wildly popular course — just 150,000 yen (roughly $1,000) — that teaches you to become a short sleeper like Hori and use your time more efficiently.
Background and Key Points of This Story
Daisuke Hori has built a following around time-management content, branding himself as a “short sleeper” who functions on just 30 minutes of sleep, and this week-long, round-the-clock broadcast was being watched as a live demonstration of that claim. The sticking point for the thread was the broadcast team’s explanation that “naps,” “passing out,” and “microsleeps” are all treated as separate from “sleep” — logic which means the “30 minutes of sleep” tagline never technically breaks, no matter how much total rest time adds up. Viewers seized on the vagueness of that distinction, and the thread lit up with half-joking comparisons to how little sleep parents of young children get. Some replies also referenced unverified rumors about Hori’s past activities; this article excludes those unsubstantiated claims.
