Japan's 'Human Washing Machine' Bathtub Offers Relief for Elderly Care

In Japan, where the population is rapidly aging, a "human washing machine" bathtub is offering a new solution for elder care. Developed by Science, a fine bubble specialist company based in Osaka, the "Mirable assist bath" uses microbubbles to cleanse the body, reducing the need for manual scrubbing.

I wish it would get clean on its own without having to scrub every nook and cranny. Isn't there something like a 'human washing machine'?

The innovative bathtub was first presented at the 2025 Osaka-Kansai Expo, where it garnered significant attention and a 98.3% satisfaction rate among 1,277 visitors. The product's design features a side-opening door, making it easier for elderly individuals with limited mobility to enter and exit.

The Mirable assist bath, a special bathtub developed by Science, is receiving high praise in the welfare field.

This technology is now being implemented in elderly care facilities, such as one in Chuo-ku, Osaka. Caregivers report a substantial decrease in physical and mental strain, as the traditional method of bathing the elderly requires considerable effort in scrubbing and supporting their bodies. Residents also express their anticipation for bath time, appreciating the comfort and ease the new tub provides.

The side of the bathtub opens like a door, allowing even elderly people with mobility issues to get in easily.

Science plans to expand the use of the Mirable assist bath from welfare facilities to general households. As Japan grapples with a growing shortage of care workers in its super-aged society, this technology is being closely watched as a potential practical solution to alleviate the burdens on both caregivers and the elderly.

Caregivers' physical and mental burden has been significantly reduced. Previously, they had to exert a lot of strength to scrub and support the elderly, but work has become easier thanks to the new bathtub.
