Japan's 'human washing machine' gets AI upgrade, cleanses in 15 minutes

In a groundbreaking innovation, Japan had introduced the “human washing machine,” which was first showcased at the Osaka Expo 55 years ago and has been revamped and unveiled recently at the Osaka Expo 2025 Healthcare pavilion.

The “human washing machine” is powered by AI technology to dry clean and dry humans in a surprisingly short span of just 15 minutes.

This innovation has been designed by a Japanese company, Science Co., and named the machine “Mirai Ningen Sentakuk,” an innovative machine that provides a luxurious spa-like experience.

How does it work?

The machine runs on cutting-edge technology utilizing advanced water jets and microscopic air bubbles to gently and effectively clean the body, enabling a unique and futuristic cleaning experience.

Back in the 1970s, the human washing machine first made headlines for automatically washing and drying users’ bodies inside a capsule.

Now the evolved version has recently been unveiled at the Osaka Expo 2025 in March.

But, this time the machine has been upgraded with unique features besides cleansing the body: the machine relaxes the mind by playing videos and music according to the user’s mental and physical health, based on a heart rate sensor.
