The story
Daisuke Hori, a streamer who bills himself as a “short sleeper” (someone who claims to need only a few hours of sleep), has been running a marathon sleep-deprivation broadcast — and thread regulars reacted when dark circles that supposedly never appear under his eyes were accidentally caught on camera. Viewers called it “about five times worse than I expected.” The stream reportedly shows him sleeping just 27 minutes over three days, and total “super chat” donations (YouTube’s paid live-chat tipping feature) have already topped 300 million yen. The thread also brought up a past case: fellow streamer Yuta Iwata previously attempted the same “Hori Daisuke Challenge” and lasted 164 hours. Commenters split between concern over the stream’s authenticity and Hori’s health, and admiration for it as a piece of content.
What people said
Even if he's just powering through it, that's some serious grit.
even though this is supposedly his normal routine.
Well, being under surveillance 24 hours a day would wear you out even if you're technically awake.
Can't even fart in peace.
I heard pulling three all-nighters in a row used to be totally normal in that industry.
Personally I need my five hours minimum.
Three days in is still manageable.
This could genuinely kill him.
so how is it only 27 minutes total over three days?
Because if he actually sleeps now, he'll crash out cold for a full day straight.
Wasn't it something like he dozed off during a massage, so that got counted against his allotted sleep time?
He's taking six baths a day,
and that's when he's actually sleeping.
He hasn't even hit a full hour of sleep total yet.
Wouldn't be surprised if more people start copying his method.
Even if you could pull it off, the brain damage from this seems brutal.
The guy who did it before him said he was hearing and seeing hallucinations by day six.
Reminder that a normal person only needs to stay awake around 17 hours.
With the days he's got left, clearing 500 million should be easy.
Would be hilarious if he got banned for dangerous conduct.
I assume the money gets forfeited if that happens?
AI handles that part these days.
The premise is that it's just his regular day-to-day life, streamed continuously.
Background and Key Points of This Story
The so-called “Hori Daisuke Challenge” — a sleep-deprivation endurance broadcast modeled on Hori’s own stunt — has spread to other streamers. On September 6, Yuta Iwata, a streamer with 30,000 subscribers, reported retiring at the 164-hour mark after experiencing hallucinations. Extended sleep deprivation is well documented to carry health risks such as auditory hallucinations and memory confusion, but the thread showed no shortage of praise calling Hori “talented as a YouTuber” or a “genius,” leaving commenters split over the ethics of monetizing this kind of risky behavior. There’s also ambiguity around the reported sleep figures themselves — between the repeated baths and dozing off during massages — leaving viewers divided on how much of the “barely sleeping” framing to take at face value.
