The familiar morning ritual in the bathroom may drastically change in the coming years. Instead of a shower, we might see a capsule that cleanses the body automatically, measures health parameters, and crafts a relaxing ambiance.
A Japanese firm based in Osaka has unveiled a technology capable of merging personal care, medical technology, and automation into a single apparatus, as reported by The Asahi Shimbun.
“A Washing Machine for Humans”: How the Novelty Functions
Science, the Osaka-based company, introduced a concept that initially seems like science fiction. The developed apparatus, named Mirai Ningen Sentakki (“Future Human Washing Machine”), is a 2.3-meter-long capsule into which a person lies down to be fully immersed in a process of “smart cleansing.” Unlike a shower or bathtub, this system handles everything autonomously—from applying the cleansing solution to rinsing off and drying.
The capsule incorporates a multi-stage cycle: gentle water misting, delicate cleaning, biometric scanning, and final relaxation.
The procedure takes approximately fifteen minutes. During this “wash cycle,” the user observes soothing visual effects displayed on a screen ahead and hears specially curated sounds engineered to induce deep relaxation.
“Our goal is to integrate the technologies of comfort, medicine, and cleanliness into one device that assists people in self-care without requiring strenuous effort,” stated a representative from Science.
Essentially, the Mirai Ningen Sentakki combines the functions of a shower cabin, a massage chair, and a medical diagnostic unit simultaneously.
Technology Inspired by a Future Expo
The concept premiered at Expo-2025 Osaka, where the project garnered considerable praise. Attendees were captivated by the notion of transforming the mundane hygiene routine into a customized “digital spa.” Following its success at the exhibition, the company announced plans to launch demonstrations in major Japanese electronics stores.
Starting next month, the device will be viewable at the Labi store branch in Ikebukuro, Tokyo. Visitors there will have the chance not only to observe the technology but also to personally experience it—though they will need to be in swimsuits, as the demonstration format requires adherence to hygiene standards.
“The Mirai Ningen Sentakki exemplifies Japanese engineering ingenuity, where imagination is transmuted into tangible domestic convenience,” read a press release from Science.
The manufacturers assure that even the demonstration capsules are fully operational: they utilize soap and water and perform automatic biometric scanning to assess skin condition, blood pressure, and pulse rate.
Details on Cost and Mass Production Prospects
The developers emphasize that the device is not currently geared toward the mass market. According to projections by the parent company, Yamada Holdings, the estimated cost will hover around 60 million yen (roughly 400,000 US dollars). This positions the Mirai Ningen Sentakki more as a luxury item or a showcase technology than a standard household appliance.
Nevertheless, interest from the hospitality sector has been so significant that the company is already preparing capsules for installation in upscale hotels. The initial prototypes are anticipated to debut in Japanese luxury spa resorts by 2026.
What makes this technology truly unique? Beyond the primary “washing” mode, the device captures data on pulse, skin moisture levels, and body temperature, subsequently offering recommendations for recuperation or rest. This approach transforms the capsule from merely a hygienic tool into an integrated component of a personal health monitoring system.
A Comparison of Traditional and “Smart” Cleansing Methods
Current shower systems provide rapid cleaning but rely entirely on the user’s input. The Mirai Ningen Sentakki automates the process, evolving it into an intelligent procedure.
To contrast:
A regular shower demands active participation, temperature regulation, and consumes more water;
A bathtub facilitates relaxation but is not inherently resource-efficient;
The Mirai Ningen Sentakki employs minimal fluid usage, with temperature and dosage controlled by artificial intelligence.
The key differentiator is the integration of diagnostics: the capsule gathers vital signs from the user’s body, something unattainable with conventional cleansing methods.
Pros and Cons of the “Human Washing Machine”
The advantages of this technology are clear:
Water and time savings;
Guaranteed hygienic safety;
Built-in health monitoring capabilities;
Elimination of manual detergent application.
Drawbacks are also present:
High price point and installation complexity;
The necessity for system maintenance;
A limited number of currently available demonstration units.
Experts speculate that with technological advancement and subsequent cost reduction, the device could eventually find its niche somewhere between standard home plumbing fixtures and advanced medical equipment.
Guidelines for Usage and Maintenance
To ensure correct operation, the manufacturer advises adherence to several key rules:
Maintain water temperature strictly within the 36–38 °C range.
Use only proprietary cleaning solutions, excluding abrasive agents.
Perform sensor calibration every three months.
Activate the automatic drying function after every cycle.
Refrain from placing sharp objects or accessories inside the unit.
Following this protocol is intended to extend the equipment’s lifespan and preserve the accuracy of the biometric measurements.
“We aim to develop a system that requires no effort from the person while delivering comprehensive body care and relaxation,” the developers further clarified in a statement to The Mainichi.
