Human washing machine aims to clean you within 15 minutes

Forget getting into a bathtub or standing under the shower, and prepare to put yourself into a washing machine. Science Co, a Japan-based shower head manufacturer, is bringing a giant human washing machine early next year. It will be showcased at Osaka Kansai Expo starting in April 2025, according to a report from Japanese newspaper Asahi Shimbun.

The idea was first initiated by Sanyo Electric Co (now known as Panasonic Holdings Corp) back in 1970 at Japan World Exposition. Science Co is just bringing the concept of a futuristic bathing experience to life by making it commercially viable with cutting edge technology.

The machine is expected to serve 1,000 general visitors during the expo, with seven to eight individuals experiencing the 15-minute "wash-and-dry" cycle each day. Reservations are being accepted via a special page on the company's website.

The new design resembles a jet fighter cockpit with a transparent cover that opens at the back. Users sit in a central seat as the device partially fills with hot water. The embedded sensors measure vital signs to ensure a safe and comfortable temperature. An AI system enhances the experience by analysing the user's emotional state and projecting calming images on the transparent cover.

For Yasuaki Aoyama, the chairman of the company, this project is deeply personal. As a child in Osaka, he waited in line to see the original exhibit at the 1970 Expo. "This new human washing machine will be a legacy from the 1970 expo," Aoyama said.
