The story

YouTuber Daisuke Hori, who calls himself a "microsleeper," became visibly unsteady and started slurring his words during a livestream in which he’s attempting a string of short, intermittent naps — and it’s become a hot topic on 5ch. After talking nonstop for ages, he suddenly went silent, worrying some viewers, while others took a more cynical view: "Bet he’s got pre-recorded footage ready to go" and "What a schemer." The thread also debated whether genuine short sleepers even exist, with some recalling a TV show that ran a similar stunt in the past, as more and more people tuned in to see how the stream would play out.

He's been talking nonstop this whole time and now he's basically silent
3AnonymousSep 11, 2026 20:42
If this is an act, the guy's a real schemer
29AnonymousSep 11, 2026 20:51
Re: #3
He's probably got pre-recorded footage on standby
4AnonymousSep 11, 2026 20:42
Guess actual short sleepers just don't exist
34AnonymousSep 11, 2026 20:52
Re: #4
Even if real ones exist, no way it's 30 minutes
Even history's most famous short sleepers maxed out around 3 hours
5AnonymousSep 11, 2026 20:42
Everyone's tuning in exactly because he looks like he's about to pass out
7AnonymousSep 11, 2026 20:42
He clearly looks like he's in bad shape
This is the climax right here
17AnonymousSep 11, 2026 20:47
If he can make big money off this, it's worth pushing through

Re: #17
Reminds me of that thing in China that was briefly a topic — people made to dance until they collapse
30AnonymousSep 11, 2026 20:51
Even I only sleep 1 hour a day and I can still hold out a bit longer than that
37AnonymousSep 11, 2026 20:53
Re: #30
You should get some actual sleep too
32AnonymousSep 11, 2026 20:52
Is this guy even yawning?
Does he not yawn at all?
40AnonymousSep 11, 2026 20:54
Re: #32
He's probably holding it back hard
52AnonymousSep 11, 2026 20:57
If he keeps this up for a week his brain's seriously going to fry 😰
55AnonymousSep 11, 2026 20:58
Re: #52
The real Guinness record for staying awake was something like 11 days, so he'll be fine, fine
60AnonymousSep 11, 2026 21:02
14,000 people watching this?
Most of them are probably rooting against him
71AnonymousSep 11, 2026 21:08
Re: #60
Seems like the haters are paying with Super Chats just to get their trash talk read out loud
73AnonymousSep 11, 2026 21:08
Don't die on stream, man
79AnonymousSep 11, 2026 21:12
Re: #73
No way he's gonna die
He's a short sleeper, remember
75AnonymousSep 11, 2026 21:09
Watching Hori's stream makes you sleepy, highly recommend
83AnonymousSep 11, 2026 21:14
Re: #75
Started watching last night and suddenly got drowsy
Ended up sleeping soundly for 7 hours
81AnonymousSep 11, 2026 21:13

82AnonymousSep 11, 2026 21:13
Is it actually possible to hold off sleep through sheer willpower until you die?
84AnonymousSep 11, 2026 21:15
Re: #82
Once you hit your limit you'd just black out, so no, not possible
87AnonymousSep 11, 2026 21:17
I wonder if he's accidentally letting one rip
91AnonymousSep 11, 2026 21:18
Re: #87
"You farted just now, didn't you~" (a well-known internet meme line)
94AnonymousSep 11, 2026 21:19
Once this project's over, I want him to gather celebrities for a 30-minute-sleep battle royale
Given how big Hori's gotten, I bet he could pull together a solid lineup — it'd definitely be entertaining
99AnonymousSep 11, 2026 21:21
Re: #94
Just imagining it sounds fun
108AnonymousSep 11, 2026 21:25
Re: #94
Takasu would probably conk out instantly (referring to Katsuya Takasu, a Japanese TV personality)
103AnonymousSep 11, 2026 21:22
He took a bath and came back to life
106AnonymousSep 11, 2026 21:24
Re: #103
I'd laugh if by the end he's taking a bath every 30 minutes
104AnonymousSep 11, 2026 21:23
Feels like some old show like TV Champion did a project like this before
I remember everyone held out until day 3 or 4
107AnonymousSep 11, 2026 21:25
Re: #104
Maybe it was 'Honoo no Challenger' (Flame Challenger, a Japanese TV show)?
129AnonymousSep 11, 2026 21:35
Re: #104
As I remember it, it ended on day 3
There was a Self-Defense Force member in it, but even he lost by the end
114AnonymousSep 11, 2026 21:28
Just measured mine and here's what it looks like


For reference I sleep 4.5 hours, so I'm probably an actual short sleeper
115AnonymousSep 11, 2026 21:28
His movements are just like mine after an all-nighter playing mahjong
119AnonymousSep 11, 2026 21:30
Re: #115
Lol, one time during an all-night mahjong session my buddy's whole body started leaning sideways
118AnonymousSep 11, 2026 21:29
Feels like he's about to say 'got my clips, so I'm calling it here'
122AnonymousSep 11, 2026 21:32
Re: #118
He's got no grit, so he'll probably just start nodding off and cut it short for no clear reason
121AnonymousSep 11, 2026 21:31
If he dies from this, is that on us?
123AnonymousSep 11, 2026 21:32
Re: #121
That's on the people throwing money at him on YouTube to cheer him on

Background and key points of this story

A "short sleeper" refers to someone whose genetics let them function on extremely little sleep without any impairment — among experts, genuine cases are said to be extremely rare, and even documented examples top out around 3 hours. The repeated 30-minute naps in this project are closer to a "sleep-deprivation / split-sleep challenge" than to the genetic short-sleeper trait itself, and the thread picked up on that distinction, with comments noting that "even a real one couldn’t do 30 minutes." Opinions split between viewers worried he was "near his limit" watching him stagger, and others who took a more cynical view that it might be staged with pre-recorded footage — some even drew comparisons to past TV shows that ran similar stunts. It’s also worth noting, as only came up within the thread, that the stream’s audience isn’t just made up of supporters cheering via Super Chat — some are paying just to get trolling comments read aloud, so it’s not a simple popularity contest.
