Japan unveils AI‑powered human washing machine at Expo 2025

Japanese engineers may have found the ideal solution for those who yearn for a soothing bath after a long day but lack the time. The "Mirai Ningen Sentakuki," or "future human washing machine." Created by the Osaka-based company Science Co., this device can wash and dry the body after performing an AI-assisted analysis.

This futuristic device, resembling the cockpit of a fighter jet or a capsule, will make its debut at the World Expo 2025 in Osaka, which runs from April 13 to October 13, 2025. There, 1,000 individuals will get the opportunity to test it and witness its capabilities firsthand. Scientists are already asserting that this extraordinary machine functions similarly to a washing machine and requires only 15 minutes to complete a human washing cycle.

Upon entering the plastic capsule, it fills halfway with warm water. Then, high-speed jets of water containing micro air bubbles are released. These bubbles burst, creating small but powerful pressure waves that cleanse the skin. According to WION Science, the same process is used to clean electronic parts that cannot be washed with chemicals.

Science Co. claims that the human washing machine not only cleanses the body but also "cleans the mind." During the washing process, electrodes in the seat collect biological information about the user and adjust the water temperature accordingly. Meanwhile, an AI sensor detects whether the user is calm or excited, playing specially selected videos inside the capsule to soothe nerves and enhance relaxation.

The device stems from a project developed 50 years ago by Sanyo Electric Co. (now Panasonic Holdings Corp.). Science Co. has not yet announced when the machine will be available for purchase or its price.
