A novel device for personal hygiene has hit the Japanese market: a capsule designed to wash humans. Measuring 7.5 feet (2.3 meters) in length, this invention was introduced at the World Expo in Osaka, held from April through October this year. Dubbed the Human Washing Machine, it promises to thoroughly clean the user's body within approximately 15 minutes.
Created by the Osaka firm Science, the device resembles a hybrid of a tub and an automated vehicle rinse. Inside, a comfortable seat akin to a recliner allows the individual to relax during the cleaning procedure.
The system disperses microbubbles and mist-like water particles across the skin, with integrated monitors tracking health indicators for user safety. Relaxing audio tracks and light displays accompany the session. Upon completion, warm air dries the body automatically, eliminating the need for any rotating mechanism typical in laundry appliances.
Science spokesperson Sachiko Maekura explains that beyond physical cleansing, the pod revitalizes the spirit by continuously observing heart rate and other physiological data.
The idea traces its origins to the 1970 Osaka Expo, where a prototype was displayed but never mass-produced. Reports from NDTV indicate the modern version draws inspiration from the company president, who encountered the early model during childhood.
This innovation targets niche applications rather than widespread consumer sales. The Japan Times reports a cost of roughly 60 million yen, equivalent to about $385,000.
Production is limited to 50 units at launch due to its sophisticated engineering and innovative features. A leading hotel in Osaka has purchased one of the initial models to offer to visitors. Meanwhile, electronics chain Yamada Holdings plans to showcase a demonstration unit in its main Ikebukuro store starting December 25, complete with a hands-on trial zone for the public.
The Expo 2025 event saw significant buzz, attracting more than 40,000 usage inquiries. Its potential to replace traditional bathing routines in homes is uncertain, given the high expense and substantial footprint as major obstacles for average users.
