Self-Proclaimed “Short Sleeper” Hori Starts 7-Day Livestream — “Is He Really Not Sleeping?” Doubts Erupt

From our other sites

The story

Self-proclaimed short sleeper Daisuke Hori has kicked off a nonstop 7-day livestream. The broadcast drew 15,000 concurrent viewers right from the start, and 5channel’s Geinou/Sports News+ board lit up with real-time commentary. The stream’s organizers have published rules such as “the stream ends immediately if a clip surfaces,” “no smart ring will be worn,” and “bathing six times a day” — but these very rules have fueled suspicion that he might be sneaking naps during baths or training sessions, turning the authenticity of the whole stunt into the central debate among viewers.

Sneering comments will also be blocked (Staff)
Lol, that's basically everyone getting blocked then
6AnonymousSep 9, 2026 19:55
Is this mob bullying…?

Re: #6
He's doing this of his own free will lol
10AnonymousSep 9, 2026 19:56
He'll probably just cut the stream whenever he gets sleepy
11AnonymousSep 9, 2026 19:56
Re: #1
Isn't it just that he can only sleep a short time because he drinks?
13AnonymousSep 9, 2026 19:57
I want to see the moment he passes out, but that's not gonna happen live, so I'll catch it on video later
14AnonymousSep 9, 2026 19:57
It'd be hilarious if halfway through he swapped himself out for Nadal in a wig, or wide-eyed Tanoshingo, pretending to be asleep (both Japanese comedians known for look-alike gags).

Whether he succeeds or fails "for real" is boring either way, so I want at least that much.
16AnonymousSep 9, 2026 19:57
If he just straight-up passes out on stream, everyone wins, right!?
18AnonymousSep 9, 2026 19:57
If it's supposedly something anyone can normally do, why make it a whole week?
19AnonymousSep 9, 2026 19:58
If you stay awake the whole time you'll d*e, so stop.
Stop pushing this "short sleeper" stuff too.
Go to sleep.
20AnonymousSep 9, 2026 19:58
If it turns out to be a gag where he just falls asleep right at the start, I'll forgive him
21AnonymousSep 9, 2026 19:58
Anyone could pull off 7 days.
There's also suspicion he's sleeping during those 6-hour baths, so he should do it for a month without bathing instead.
Skipping baths for a month won't kill him, so there shouldn't be a problem.

Re: #21
Well, if he's taking naps, a week does seem doable.
My limit was staying up 3 nights straight, but with naps I could probably manage it too.
23AnonymousSep 9, 2026 19:59
Who cares about some total stranger's sleep schedule
63AnonymousSep 9, 2026 20:06
Re: #23
Well, when someone's bragging about their sleep time, of course people are gonna care about it.
In a bad way, that is.
24AnonymousSep 9, 2026 19:59
Can't wait to see what kind of cheating he pulls
25AnonymousSep 9, 2026 19:59
He's not gonna claim a 3-hour "connection issue," right?
26AnonymousSep 9, 2026 19:59
Wasn't the rule that it ends the moment a clip gets posted?
Bet the staff will just clip it themselves to force a shutdown once things get dicey.
28AnonymousSep 9, 2026 19:59
He's got eyes drawn on his eyelids lol
44AnonymousSep 9, 2026 20:02
Re: #28
What is this, Lady Gaga?
33AnonymousSep 9, 2026 20:01
You've probably got someone in your life too who tells a little lie just to get attention.
Don't corner the guy like this, cut him some slack.
129AnonymousSep 9, 2026 20:19
Re: #33
If he'd just admit it and apologize, then…
47AnonymousSep 9, 2026 20:03
Sounds like the stream cuts out during his lectures
51AnonymousSep 9, 2026 20:03
Re: #47
Then the whole thing's pointless
64AnonymousSep 9, 2026 20:06
Guinness doesn't even certify consecutive no-sleep records anymore because they're life-threatening
83AnonymousSep 9, 2026 20:10
Re: #64
It's not "no sleep," it's "short sleeper" lol
72AnonymousSep 9, 2026 20:07
By the way, here are the rules:

– The stream ends immediately the moment a clip appears.
– No smart ring will be worn, since wearing one isn't part of my normal everyday routine.
– There are daily training sessions with program participants, and since the methods of the sleep-improvement program can't be made public, there will be a few hours of stream downtime.
– Bathing 6 times a day would mean being fully nude, so if that violates YouTube's terms, it won't be shown.

Also, note that commenting "go to sleep" counts as defamation and will result in legal action.

Re: #72
He's clearly asked a buddy to upload a clip so this can end
86AnonymousSep 9, 2026 20:11
Re: #72
He could just run a silent overhead camera during the training sessions instead
107AnonymousSep 9, 2026 20:16
Re: #72
He didn't even need such a troublesome set of rules —
if he passes out it just doesn't count, so this is easy mode.
92AnonymousSep 9, 2026 20:12
He's probably off-stream for like half a day between baths and training sessions, right? He's definitely sleeping lol
98AnonymousSep 9, 2026 20:14
Re: #92
He's probably sleeping during the baths.
Well, if he's doing strength training right after getting out of the bath,
he must be seriously exhausted.
101AnonymousSep 9, 2026 20:15
There have been people who stayed awake over 100 hours straight playing Dragon Quest, so 7 days should be doable —
that's what I thought, but then what's with the 6 baths a day?
112AnonymousSep 9, 2026 20:17
Re: #101
He sleeps in the bath, and when time's up
staff wake him.
103AnonymousSep 9, 2026 20:15
15,000 concurrent viewers right out of the gate.
The real test'll be around 2am, that's when it gets interesting.
Wonder how many concurrent viewers he'll have by day 7?


Background and points of debate

“Short sleeper” refers to a physical trait some people are born with that lets them function on very little sleep without ill effects; the claim that this can be acquired later through training is said to have little medical backing. This particular stunt is an attempt to demonstrate the truth of that claim via a continuous 7-day livestream, but the rules the organizers laid out — the stream ends the instant a clip surfaces, broadcasting stops during training sessions, and bathing happens six times a day — end up making it harder, not easier, for outside viewers to confirm whether he’s really staying awake. The bathing and training blocks becoming de facto black boxes was the central source of suspicion on the thread. Though not mentioned in the original article, prolonged sleep deprivation carries serious health risks, and Guinness World Records has stopped certifying related records for safety reasons. Seen in that light, viewers’ skepticism isn’t out of left field — it’s a continuation of the same authenticity disputes that have dogged similar “no-sleep challenge” stunts in the past.
