Osaka-based Science Co., renowned for its cutting-edge showerheads and bathtubs, is preparing to unveil the “Mirai Ningen Sentakuki” (Human Washing Machine of the Future) at the Osaka Kansai Expo in April 2025. This innovative device reimagines a concept first introduced over half a century ago.
The original human washing machine debuted at the 1970 Osaka Expo, created by Sanyo Electric Co., now Panasonic Holdings Corp. Its futuristic egg-shaped design and bubble-cleaning technology captivated audiences, leaving an indelible mark on Yasuaki Aoyama, then a curious fourth-grader. Today, as the chairman of Science Co., Aoyama aims to build on this legacy with a thoroughly modern update.
The new model uses microscopic air bubbles to ensure complete cleaning, in contrast to its predecessor, which employed huge air bubbles and plastic balls for cleaning and massaging. Modern sensors keep an eye on the user’s biological information, including pulse, to precisely regulate the water’s temperature. The machine’s transparent cover displays pictures that are either relaxing or invigorating based on an embedded AI system’s assessment of the user’s emotional state.
The cockpit-shaped washing machine partially fills with warm water as the user reclines in the central seat. Millions of microscopic bubbles are then released, delivering a spa-like experience that cleanses and relaxes. Science Co. plans to let 1,000 visitors experience this revolutionary technology during the expo.
Aoyama described the project as a tribute to the 1970s innovation, reflecting Japan’s ongoing commitment to technological ingenuity. Though initial details emerged in 2022, the machine’s design has evolved significantly while adhering to its 2025 launch target.
As anticipation builds, Science Co.’s Mirai Ningen Sentakuki promises to redefine personal hygiene, blending advanced technology with relaxation. Visitors to the 2025 Osaka Expo are in for a one-of-a-kind experience that marries nostalgia with futuristic innovation.
