The story
Businessman Daisuke Hori (42), who calls himself a “short sleeper,” has wrapped up a seven-day continuous YouTube livestream that ran from the 9th. Hori founded the Japan Short Sleeper Training Association and claims to have lived on about 30 minutes of sleep a day for the past 17 years. The stream had its share of drama — including an accident where his genitals were briefly exposed on camera, forcing a pause — and at times drew over 100,000 simultaneous viewers. On 5ch, opinions were split: some pointed to smart ring data suggesting he actually slept around 50 minutes, dismissing the whole thing as “basically an endurance contest,” while others praised his stamina and called the completed run “entertaining.”

What people said
Even if it's not 30 minutes, sleeping 2 hours a day every day would still deserve praise.
He worked hard — why won't anyone give him credit?
He's not supposed to be "trying hard" though — this is supposed to be his everyday normal lol
Nah, he shouldn't need to try hard at all — it's supposedly just what he's done every day for 17 years.
He just went without sleep and white-knuckled it while stumbling around exhausted.
It turns out his claim — that 30 minutes of sleep a day (plus a few power naps) lets him maintain performance and live a full, productive life — was a lie.
Also, he told way too many lies during the live stream itself.
This guy is not a short sleeper at all.
A week-long livestream would be brutal even for someone who sleeps normally.
He was responding to comments the whole time too, so it's basically like working nonstop.
Honestly surprised he didn't work himself to death.
Next I want him to ride a motorcycle around all of Japan.
Exactly this.
Felt like the 24-Hour Television from back when Tamori was hosting it — "TV Dream Archipelago" (the show's old tagline).
There was even a little "wardrobe malfunction" thrown in too.
Did anyone catch the time he rode in a taxi?
Honestly it just looked like an endurance contest, but his eyes were bright red and swollen, so…
That's just because you barely watched any of it.
I'm a corporate slave in a busy crunch period and haven't even averaged 2 hours of sleep a day for the past two weeks.
According to the smart ring readings, about 50 minutes a day.
His course enrollments are probably going to shoot up.
What's the one thing about Daisuke Hori you respect most?
I don't respect him, but he's entertaining.
being able to stay awake that long is still impressive.
Maybe he really does have some unusual physical constitution?
Before that suspicious 2-hour massage break, Hori was clearly at a "can't function in society" level, so if that counts as fine, sure, anyone could stay awake.
Nah, come on, he wasn't doing anything meaningful lol.
He was just a guy staying awake and fighting off sleep.
Under 2 hours of sleep would be amazing.
At 3 hours, a lot of people could probably pull that off if they pushed themselves.
Wonder what the real number actually was.
Though he's also got a ton of haters.
He was already a billionaire before this.
Though he'd probably claim micro-dishes and "power meals" don't count as real meals, so he can eat as many of those as he wants.
Sleep is insanely important for building muscle, you know (lol)
Background and Points of Debate
Medically, a “short sleeper” refers to someone whose body suffers no ill effects from sleeping three to four hours or less per day — a trait confirmed in only a tiny number of people, tied to genetic factors. Hori founded an association claiming this trait can be acquired later in life, and runs paid courses around it; this livestream was seen partly as a demonstration meant to prove that claim. Opinions on the thread split along a line of what counts as “success”: some praised his stamina and the fact that he completed the full run, while others gave more weight to the smart ring data suggesting he’d actually slept longer than he claimed. Note that the sleep figures during the stream were based on Hori’s own self-reports and readings from a device he brought himself — the article gives no indication that a hospital or other third party independently verified them.
