Daisuke Hori, born November 2, 1983, is a businessman, author, and bodybuilder from Amagasaki City, Hyogo Prefecture. He serves as the representative director of the Japan Short Sleeper Training Association and the representative director of GAHAKU Co., Ltd., and is also known as the trademark holder of "Short Sleeper."
He says he has been sleeping only about 30 minutes a day for approximately 17 years, and has offered sleep improvement programs and a short-sleep method called "Nature Sleep." He is also dedicated to body sculpting, and placed 5th in the Best Body Japan national competition in the Best Body category in 2025.

3. The story behind the snoring incident during the head spa.
The incident occurred on September 10, 2026, the second day of the broadcast. While Mr. Hori was receiving a head spa massage from a beauty therapist, he was shown sleeping peacefully and emitting what appeared to be snoring sounds.
The beauty therapist performing the treatment appeared to be struggling to contain her laughter and later posted an apology on her Twitter account to the effect that she had "put him to sleep." It is said that Mr. Hori slept for about 27 minutes, and when he woke up, he had a sleepy expression on his face. The collaborative video was later deleted, which led to further criticism.
Furthermore, subsequent scenes of her appearing to fall asleep during treatments such as facials, which require her to close her eyes, sparked debate among viewers.
4. Daisuke Hori's own explanation: "Microsleep"
In response to the accusations of snoring, Mr. Hori explained that it wasn't normal sleep, but rather that he had entered a state of "microsleep," which is a very short period of sleep, about 10 times.
Furthermore, it is said that Hori added a rule in a subsequent broadcast stating that "napping is allowed." Hori had never originally declared that he "doesn't sleep at all," but rather claimed that he leads a highly satisfying life with only about 30 minutes of sleep a day. Therefore, any scene in which he appears to be sleeping, even briefly, tends to cause controversy.
5. Exchange with Hosokawa Valentine
On September 12, 2026, martial artist and businessman Valentine Hosokawa responded on X. In a live stream where he proved he had been sleeping only 30 minutes every day for 17 years, Hosokawa posted a strong criticism to the effect that it was strange to go out of his way to get head spas and facial treatments where you have to close your eyes.

In response, Mr. Hori sharply retorted, "Don't jump to conclusions based on a narrow perspective and baseless speculation." Mr. Hosokawa fought back again, and the exchange escalated into a heated debate, with Mr. Hori responding, "Look at a week's worth of data before you comment."
On the other hand, some calm comments have been made on X, suggesting that there is no need to stick to one's beliefs to the point of damaging one's health, and that the theme should be how to use one's waking hours meaningfully. There have also been instances where Mr. Hori appeared sleepy and vacant, leading to concerns about his health.
6. The dispute with Mikiya Takasu that is behind the controversy
The background to this challenge lies in the ongoing debate surrounding sleep that Mr. Hori has been involved in. Mr. Hori has repeatedly discussed sleep with Dr. Mikiya Takasu, director of Takasu Clinic Nagoya, which has attracted considerable attention.
Furthermore, Hori has faced criticism from people skeptical of short sleep duration, and in a live stream, she revealed her distress over receiving over 10,000 instances of slander and defamation. It was in response to these doubts that she embarked on this large-scale challenge of a week of live streaming to prove her claims.
