Science Group will be exhibiting in the Osaka Healthcare Pavilion at Expo 2025.
Water has been Science’s mission since its establishment.
We will leverage the fine bubble technology this dedication has enabled to create an exhibit that lets people actually see and touch the possibilities of water, and show visitors a glimpse of what life will be like in the future.
Science’s Vision of the
Possibilities of Water


A Future Where
You Will Be Able to
Cleanse Both Body and Soul
Without Lifting a Finger
Science is currently developing the Mirai Human Washing Machine (tentative), a product that will change the concept of bathing, cleansing and refreshing not only the body but also the soul. Our system doesn’t just clean the body. Measuring the bather’s biometric data using sensors at the back of the system, the Mirai Human Washing Machine becomes a space that makes it possible to achieve a greater degree of relaxation and rejuvenation, creating new value.
Science will be exhibiting the Mirai Human Washing Machine in the Osaka Healthcare Pavilion at Expo 2025. Come visit us at the expo and experience the Mirai Human Washing Machine for yourself! As your body is cleansed without lifting a finger, so too will it feel as if your very soul is being refreshed in what is sure to be an unforgettable experience.


Osaka Healthcare Pavilion
Based on the objectives of Expo 2025, all the minds and ideas of Osaka are being marshalled to create an exhibition that will enable visitors to experience “life,” “health,” and the way we will live in the near future, while conveying the vitality and attractiveness of Osaka as a city to as many people as possible around the world. The aim of the pavilion is to deliver excitement and moments full of surprises and new discoveries, and, as an interactivity-focused exhibition, to live on in the memories of attendees and push them to try new things through hands-on experiences and co-creation.
Osaka chose “reborn” as the theme of its exhibition at the heart of Expo 2025.
This theme encompasses the ideas of “people can be reborn” as well as “taking a new step forward.”
Bringing Excitement and Joy to All
The most important goal of the Science Group is to achieve its management
philosophy—To continue to bring excitement and joy to all we are involved with.
At Expo 2025, we will show the world that our fine bubble technology
can be used not just in consumer products but also to help
achieve the United Nations’ Sustainable Development Goals (SDGs) by 2030 and
create new value in such diverse fields as medicine, agriculture, industrial cleaning, and fisheries.
