A futuristic "human washing machine" that once caused a sensation at the 1970 Japan World Exposition is set to make a comeback at the upcoming Osaka Kansai Expo in April 2025. The original machine, exhibited by Sanyo Electric Co. (now Panasonic Holdings Corp.), failed to gain commercial success. However, Osaka-based showerhead maker Science Co. is now developing a new version incorporating cutting-edge technology.
This "Mirai Ningen Sentakuki" (未来人間洗濯機 human washing machine of the future) will be showcased at the Osaka Healthcare Pavilion. Visitors to the expo will have the chance to experience this futuristic device firsthand. The company is also planning to release a home-use version of the machine. "We're about 70% of the way there," said Yasuaki Aoyama, the company chairman, during a lecture on October 23. "We plan to offer 1,000 general visitors an opportunity to use it during the expo."

Aoyama said seven to eight people will be able to experience a "wash-and-dry" job each day. The company accepts reservations on a special page of its website. The human washing machine is shaped like the cockpit of a jet fighter. It even has a transparent cover that opens to the back. When the bather sits in the seat in the centre, the device partially fills with hot water. Sensors embedded in the seat measure the person's pulse and other biological data to ensure the bather is washed at an appropriate temperature. At the same time, an AI system determines whether the user is calm or excited and projects images inside the transparent cover to help the person feel refreshed. A wash and dry takes 15 minutes. Sanyo Electric's human washing machine exhibited during the 1970 event was called Ultrasonic Bath. When the bather sat inside the egg-shaped tub, it automatically filled with hot water and emitted ultrasound waves. It also released plastic balls to massage the person's body.
