Japan has unveiled one of the world’s most expensive personal care devices: a 60 million yen bathing capsule (around USD 400,000). Nicknamed the “human washing machine,” the fully automated pod can deep clean an adult from head to toe in just 15 minutes while simultaneously tracking their health.
The device became a breakout star at Expo 2025 Osaka, one of the event’s most talked about examples of Japan’s fusion of wellness, robotics, and high tech design.
A Spa Treatment and Health Monitor in One
The capsule is large enough for an adult to recline comfortably. Once sealed, it begins a programmed cleansing cycle using ultra fine microbubble technology, a premium spa method widely used in Japan to remove oil, dirt, and dead skin cells at the pore level.
Soft background music plays during the process, transforming what could feel clinical into a calming, resort style experience.
The machine also includes a built in sensor system that monitors heart rate and other vital signs. This safety feature is designed to prevent fainting, panic, or medical incidents, making the device appealing not only to luxury consumers but also to Japan’s aging population.
Fifty Years in the Making
According to the company behind the invention, the concept traces back to 1970, when an early prototype captured public imagination. The firm’s current president, who first saw the machine as a ten year old, spent decades refining it into a commercial product fit for the modern wellness market.
At Expo 2025, the updated version generated long queues and contributed to the exhibition’s impressive 27 million visitors over six months.
Who’s Buying a USD 400,000 Bathing Machine?
The first purchase came from a luxury hotel in Osaka, which plans to offer the capsule as part of an exclusive wellness experience. A major electronics retailer has also bought a unit to showcase as a draw for customers.
Despite global buzz, the manufacturer says it will produce only about 50 machines across Japan, positioning the product as an ultra rare, high end item for hotels, wellness resorts, and collectors of futuristic tech.
More Than Hygiene: A New Category of Luxury Wellness
Sellers describe the machine as offering not just physical cleansing but “mental purification,” blending spa culture with biometric monitoring and automated comfort.
As wellness tech becomes a booming global sector, Japan’s USD 400,000 “human washing machine” hints at a future where personal care, relaxation, and health diagnostics converge inside a single, automated capsule.
