The electronics store chain “Yamada Denki” will begin selling the “Human Washing Machine” on December 25th. It will also allow customers to test this innovative invention in its branches in Japan, after the great success it achieved during its presentation at Expo 2025 in Osaka.
The device, developed by Japanese technology company Science Inc, combines full-body cleaning and relaxation by displaying music and images, as well as monitoring the user’s vital signs to ensure a safe and distinctive experience.
The device is known as the “Human Washing Machine,” where a person can lie in a capsule 2.3 meters long, and the cleaning process begins using “microbubble” technology, which is very small water bubbles that penetrate the pores and gently remove dirt and dead cells. In addition, there is a fine water spray that distributes the water on the body evenly without strong pressure, and then the person is dried automatically without the need for any manual intervention or the use of towels.
This entire process takes only 15 minutes, from the beginning of the shower to the end.
Company spokeswoman Sachiko Maekura explained that the device is not limited to cleaning the body, but also aims to monitor heart rate and other vital signs during use. When the user sits on the central seat inside the capsule, the device begins to gradually fill the lower part with hot water, while sensors embedded in the seat measure heartbeats and record other biological data to precisely adjust the water temperature to suit his body.
At the same time, the artificial intelligence system analyzes the user’s condition to determine whether he is in a state of complete relaxation or suffering from stress or hyperactivity, and then the experience is automatically adjusted according to his condition.
Sachiko Maekura indicated that the great interest shown by companies and institutions from outside Japan after seeing the device at Expo 2025 in Osaka encouraged the company to move from the pilot stage to producing the device and launching it in the markets.
She added that the first washing machine sold went to a hotel in Osaka to provide this service to its guests, while Yamada Denki will display experimental models in its stores starting on December 25, with a dedicated place to experience the device for visitors.
The company plans to produce only about 50 devices, at a price estimated at about 60 million Japanese yen (about $385,000) per unit, due to its uniqueness and complexity of its technologies. (24)
