This Japanese Company Is Working on a Human Washing Machine

Science, a Japanese technology company specializing in bathroom and kitchen innovation, recently unveiled plans to produce a washing machine for humans.

Believe it or not, the concept of a human washing machine isn’t new. At the 1970 Osaka Expo, Japanese electronics giant Sanyo Electric showcased its ‘Ultrasonic Bath’, a human washing machine that cleaned, massaged, and dried the occupant in a fully-automated 15-minute cycle”. The concept never really took off as a commercial product, but now another Japanese technology company wants to take a shot at it, promising to deliver a modern take on the human washing machine by 2025.

Osaka-based Science Co. Ltd., a company known for its many innovations in bath and kitchen technology, has announced its plans to create its own version of the human washing machine as part of its Mirable product line. Named ‘Project Usoyaro’, the latest “fine bubble technology”, as well as a variety of monitoring sensors and an artificial intelligence system to produce a complex bath experience.

Science has stated that the goal of Project Usoyaro is not solely to thoroughly clean the body of the user, but also to provide a healing space where you can relax and unwind to the sound of soothing music and the view of images displayed on a water-resistant display inside the machine.

Sensors inside the washing machine will measure the state of sympathetic and parasympathetic nerves, and the built-in AI will use the collected data to create the most comfortable atmosphere possible.

Project Usoyaro is apparently a pet project of Science Co. Ltd. chairman Yasuaki Aoyama, who was only 10 years old when Sanyo’s original human washing machine was unveiled in Osaka. He was so fascinated by the invention that he decided to improve on it if he ever had the chance.


Science expects that Project Usoyaro will result in a functional human washing machine by 2024, which the company hopes to showcase at the 2025 Osaka Expo.
