OSAKA, Dec 21 — A futuristic “human washing machine” that captivated thousands of visitors during its showcase at the Osaka World Expo is now moving closer to reality, with plans for commercial release in 2026, according to Kyodo News.
The machine, developed by Japanese shower and bathing equipment company Science Co., is capable of washing and drying the body automatically in a single session lasting around 10 minutes. Unlike conventional bathing methods, it does not rely on shampoo or scrubbing. Instead, it utilises sophisticated “fine-bubble” technology that produces micro bubbles small enough to penetrate skin crevices, providing deep and comfortable cleansing.
Science Co. confirmed that initial deployment of the machine will be targeted at nursing homes and elderly care facilities, with the first units expected to be delivered as early as March next year. Public sales will follow toward the end of 2026. The device is expected to be priced at approximately 1.45 million yen (US$9,200).
The machine is designed with accessibility and ease of use in mind. Structured like a raised rectangular bathtub, it includes a side-entry door that allows users to step in and sit down before the automated washing process begins. After washing, the machine transitions into a drying mode, eliminating the need for towel use.
Company chairman Yasuaki Aoyama said the innovation aims to significantly ease the burden of bathing for both users and caregivers. With Japan experiencing one of the world’s fastest-ageing populations, many elderly citizens rely on external assistance for daily hygiene. Automating the bathing process could reduce caregiver workload, improve efficiency and offer a safer bathing environment.
The idea of a human washing machine is not entirely new. The concept was first introduced at the Osaka Expo in 1970 as a futuristic vision. However, only now has technology matured enough to turn that concept into a practical consumer product. The device’s reappearance at this year’s Expo, where around 1,300 visitors tried it first-hand, proved that interest remains strong.
Science Co. also revealed that interest is emerging from abroad, with inquiries coming from multiple countries keen to explore its potential applications, including healthcare, rehabilitation facilities and luxury wellness markets.
Japan views such innovation as part of its broader strategy to enhance quality of life through technology. The success of this machine may pave the way for more automated human care devices, reshaping how societies manage hygiene, elderly care and daily living support.
With its anticipated launch, the human washing machine may soon shift from a futuristic concept into a practical everyday reality.
