Japan has officially launched one of its most unusual and futuristic consumer products: a fully automated human washing machine that can clean, rinse, dry, and soothe the occupant in just 15 minutes. Known as the Mirai Human Washing Machine, the device was created by Science Inc., a Japanese firm specializing in high-end bathing technology. After drawing massive attention at the 2025 Osaka World Expo, it is now officially available for purchase.
The concept feels like something from science fiction. Users step into a large reclining pod where the door closes around them. Inside, the machine uses ultra fine microbubbles to clean their entire body, reaching deep into pores to remove oil, dirt, and dead skin. The system then rinses and dries the user while playing relaxing music intended to calm the mind. Company spokeswoman Sachiko Maekura told local media that the device is designed to wash not only the body but also the soul.
While it may seem like a brand new idea, the concept actually dates back to the 1970 Osaka Expo, where Sanyo Electric unveiled a similar prototype. Science Inc. chairman Yasuaki Aoyama saw that original exhibit as a child and revived the idea using modern spa and sensor technology. The result is a pod measuring about 8.2 feet long, 3.2 feet wide, and 8.5 feet tall, big enough for most adults to recline comfortably.
Safety was a major design focus. The pod includes sensors that monitor vital signs in real time to prevent fainting or panic. If anything seems off, the system can pause automatically. The microbubble cleaning method is already widely used in Japanese spas and clinics because of its ability to clean gently without the need for scrubbing.
The catch is the price. The Mirai Human Washing Machine costs around 60 million yen, roughly 385,000 dollars. Science Inc. expects it to be adopted primarily by luxury hotels, high end spas, onsens, theme parks, and wellness resorts rather than by typical households. Only 40 to 50 units will be hand built in the first production run. One Japanese hotel has already purchased the first unit, and several others have placed reservations.
Even so, the company says a more affordable home version may eventually arrive. For now, the human washing machine stands as the latest example of Japan’s drive to automate care, comfort, and daily life as its population ages and demand grows for advanced personal assistance technology.
