Scientists Invent Giant Dishwashing Machine for Entire Human Bodies

Hello!

Rinse Cycle

A Japanese showerhead maker called Science Co. is planning to debut what it calls the “human washing machine of the future” at the Osaka Kansai Expo in April 2026. While the target customer remains unclear, the concept has certainly captured widespread attention.

The device resembles a hypersleep chamber from the film Aliens (1986). It promises to wash and dry a person in roughly 15 minutes, according to Japanese newspaper The Asahi Shimbun. Beyond basic cleaning, the machine is said to deliver therapeutic benefits by adapting to the user’s physical and mental state.

The Mainichi Shimbun reported that built-in sensors scan the person’s back to measure stress and fatigue levels. In response, the device projects calming imagery synchronized with the user’s condition, creating a relaxing environment during the cycle.

Blast From the Past

Although the technology sounds cutting-edge, the human washing machine concept dates back more than five decades.

The first prototype was unveiled at the Osaka Expo in 1970. Developed by Sanyo Electric Co. (now part of Panasonic), the pod filled with hot water, generated fine bubbles, and used ultrasonic waves to clean the body.

“We aimed for small bubbles, which we thought would remove more dirt, but it was technically difficult,” former Sanyo engineer Eiji Yamaya told The Mainichi Shimbun.

Sanyo’s version never reached mass production. Today, 84-year-old Yamaya and 90-year-old former Sanyo designer Manatsu Ueda are advising Science Co. in hopes of a different outcome this time.

After testing the device with 1,000 participants at the Osaka Expo in April 2026, Science Co. intends to adapt the human washing machine for home use. “We’re about 70 percent there,” company chairman Yasuaki Aoyama stated during a lecture this fall.

No problem, as long as the machine leaves users 100 percent clean.
