Japanese innovation has reached a new frontier in personal hygiene with the development of an AI-powered “human washing machine.” Created by showerhead company Science Co., this futuristic bathing pod promises the ultimate cleaning experience, blending cutting-edge technology with relaxation.

Chairman Yasuaki Aoyama introduced the invention, named the Mirai Ningen Sentakuki, at a lecture at the Osaka Healthcare Pavilion in October. While still in development, the device is about 70% complete and set to debut at Expo 2025 in Osaka.

How It Works

This enclosed capsule, resembling a high-tech cryogenic chamber, provides a full wash and dry cycle in just 15 minutes. After stepping into the pod’s central seat, users are partially submerged in water. Embedded sensors measure vital signs like pulse and temperature to tailor the bathing experience.

High-speed water jets infused with microbubbles—each just 3 micrometers wide—gently cleanse the skin, creating pressure waves powerful enough to remove grime. This technique, typically used to clean delicate electronic components, ensures a thorough yet gentle wash.

Beyond the Bath

The Mirai Ningen Sentakuki offers more than just physical cleaning. Integrated AI analyzes the user’s biological data to determine emotional states, projecting calming videos inside the pod to enhance relaxation. Science Co. claims the experience provides both a psychological and physical “deep clean.”

A Legacy of Innovation

The idea isn’t entirely new. The concept is inspired by the Ultrasonic Bath, a machine showcased at the 1970 Japan World Expo by Sanyo Electric Co. Like its successor, it combined water, ultrasound waves, and plastic balls to cleanse and massage the user. Aoyama, who experienced the original as a child, dreamed of bringing a modernized version to life.

“We want to offer a new human washing machine as a legacy from the 1970 expo,” Aoyama said.

What’s Next?

Visitors to Expo 2025 will have the chance to try the Mirai Ningen Sentakuki, with reservations already being accepted on Science Co.’s website. For those unable to make it to Osaka, the company plans to release a home edition in the future.

This innovative machine may not replace traditional showers just yet, but it offers a glimpse into how AI and robotics could transform daily routines.
