The Japanese Man Who Sleeps Only 30 Minutes a Day
This article explores the extraordinary lifestyle of Kudafu, a 41-year-old Japanese man who has gained fame for sleeping only 30 minutes a day for the past 16 years. He is known as the "Short-Sleeved Bizo of Japan" and the "God of Cultivation" due to his incredibly productive and energetic life.
Japan's Sleep-Deprived Culture
Japan is known for its culture of long working hours and relatively short sleep durations. In 2024, data from the sleep game Spirit Pokémon Sleep revealed that Japan has the lowest average sleep time among seven countries, at just 5 hours and 52 minutes. Kudafu's extreme sleep schedule further contributes to this trend.
Kudafu's Early Life and Transformation
Born in Shenghu City, Bingku County, Kudafu initially struggled to find his path. He experimented with music, design, and even appeared on TV shows as a speed master. However, he felt unfulfilled both materially and emotionally. To overcome the pain of heartbreak, he dedicated himself to hard work and self-improvement. He became a band guitarist and developed a passion for oil painting.
The Decision to Sacrifice Sleep
As his ambitions grew, Kudafu realized he needed more time. He came to the conclusion that sleeping less than eight hours a day would allow him to work twice as much as others. He began to experiment with reducing his sleep. Initially, he slept for five hours a day, then gradually reduced it to three. At the age of 25, he transitioned to sleeping only 30 minutes a day.
Kudafu's Daily Routine
Kudafu's life is a testament to his dedication to maximizing productivity. His day is packed with work, exercise, and self-improvement.
-
He works for extended hours, often starting before dawn.
-
He dedicates four hours a day to working out.
-
He takes multiple showers throughout the day, claiming it helps him stay awake.
-
He carefully manages his diet, eating small portions and chewing each bite thoroughly to prevent blood sugar fluctuations.
-
He even spends time "blackening" himself in the sun, believing it makes him more resilient.
Program Investigation
A Japanese program team investigated Kudafu's claims, arriving at his home at midnight to find him working. They observed him sleep for only 30 minutes and then immediately resume his activities. This confirmed the extraordinary nature of his sleep schedule.
The Philosophy of Short Sleep
Kudafu believes that sleeping only 30 minutes a day grants him an extra year of productive time compared to others. He claims that his mind remains sharp, his eyesight is unaffected, and his body feels younger than its actual age.
Spreading the Message
Kudafu has established a company to teach others his method of short sleep. He has reportedly trained over 1,200 students, and even his wife sleeps only three hours a day under his influence.
Cautionary Note
It is important to note that Kudafu's lifestyle is extreme and not scientifically validated. His claims about the benefits of minimal sleep lack evidence and should not be easily imitated. Maintaining a healthy sleep schedule is generally recommended for overall well-being.
