Japan has just taken personal hygiene to a whole new level.
Science Co., a Japan bathroom fixture manufacturer, unveiled its latest innovation, known as the “Human Washer in the Future”, a fully automated bathroom system that makes showering a hands-free, spa-like experience. In Japanese, it’s known as Mirai Ningen Sentakuki.
The futuristic contraption, currently on display at the 2025 Osaka Expo, has already drawn massive interest and intrigue from the crowds. According to a poll conducted by the company, eight out of 10 users were happy with the experience, while another one in five described it as satisfactory.
Exploring the human washing machine
The New machine looks like a sleek, oversized bathtub with a canopy that envelops the user. Once inside, the user reclines into the tub’s plush, contoured interior, and the door seals shut.
A built-in display is activated, showing calming visuals like gentle ocean waves, soft sunsets, and soothing shore sounds.
Then, warm soap water fills up to the chest level automatically, washing the user without any movement required. The entire process takes just a few minutes and leaves participants refreshed, relaxed, and clean.
An era of automated cleanliness
Unlike traditional showers or bathtubs, the Human Washer doesn’t depend on manual controls. The precision sensors in it constantly measure the water level, temperature, and flow rate to maintain optimal comfort.
The system keeps the soak at a perfect 100 degrees Fahrenheit (38°C) – the ideal warmth for relaxation – and slightly lowers the temperature during the rinse cycle for a gentle refresh.
The company also emphasized that it’s not just about convenience but also sustainability. The washer minimizes water usage by intelligently recycling and filtering during each stage.
The built-in speakers inside the canopy create an immersive experience. The visuals, sourced from nature documentary footage, loop for about five minutes per wash cycle, giving users enough time to unwind without overstaying their soak.
The overall design philosophy, Science Co. said, is rooted in Japan’s centuries-old bathing culture, which values both hygiene and relaxation as essential parts of daily wellness.
From concept to crowd favorite
Science.Co first talked about the Human Washer concept years ago as a vision of the future bathroom. With sensor technology, automation, and design, it has now transformed into a fully functional prototype.
Company representatives said the product wasn’t just for tech enthusiasts. It’s designed for anyone seeking comfort, accessibility, or time efficiency in their daily routine.
Future versions could also include AI-driven personalization adjusting settings based on individual preferences for temperature, scent, or sound.
Drawing the inspiration
The idea of a human washing machine isn’t entirely new. Sanyo Electric Co. introduced the first version of this concept in the 1970 Japan World Expo. That prototype used hot water, bubbles, and plastic massage balls for cleaning and providing a soothing experience.
However, the machine never made it to commercial production. Science Co. chairman, Yasauki Aoyama, was inspired by that innovation and reimagined to what it looks today. He also confirmed that 1,000 guests have already experienced the futuristic device.
The company plans to launch a mass-market version after the Expo. With no release data or price tag confirmed, it remains positive about the product’s potential to impress the masses.
