Named Mirai Ningen Sentakuki (translated as “Washing Machine for Humans of the Future”), the device blends futuristic technology with practical self-care.

How It Works:
The device, shaped like a cabin, fills with water once the user sits on the central seat. Equipped with sensors, it monitors the user’s pulse and other biological data to maintain an optimal and comfortable water temperature. During the process, the system projects calming images onto the cockpit’s transparent glass to enhance relaxation.

"The cockpit partially fills with hot water when the user takes a seat. Sensors built into the seat measure the user’s pulse and other biological data to ensure a comfortable washing experience. Simultaneously, the AI system analyzes whether the user is relaxed or stressed and displays visuals to help create a rejuvenating experience," explained the developers.

Testing and Future Plans:
The prototype is set to undergo public testing at the Osaka Kansai Expo in April next year. Up to eight people daily will be able to experience a 15-minute “wash and dry” session by reserving a spot at the expo’s healthcare pavilion, where several units will be showcased.

Science Co. also plans to develop a home-use version of the device, which could bring this futuristic washing experience to households.

Historical Context:
This isn’t Japan’s first foray into futuristic bathing solutions. In 1970, Sanyo Electric Co. introduced a “human washing machine” at the Osaka Expo, creating a stir with its innovative concept. However, it failed to achieve commercial success.

With advancements in AI and sensor technology, the Mirai Ningen Sentakuki may have better chances of finding a market, revolutionizing how people approach personal hygiene and relaxation.
