<The future offered by the "Future Human Washing Machine">

1.  [Wash your body] No scrubbing, fine bubble wash

 Equipped with the latest technology from Science Co., Ltd., known for its Mirable, the ultra-fine bubbles and microbubbles gently remove dirt and sebum deep within pores without the need for soap.

2.  [Cleanse your soul] AI guides optimal relaxation

While you bathe, a sensor on the back monitors your heart rate and other biometric information in real time. AI analyzes your stress and fatigue levels. The capsule then delivers the healing you need most at this moment through immersive images projected on a large display and music transmitted via cartilage conduction, helping to restore your mental state.

3.  [Check your health] Bathing can be a part of daily health monitoring

Your daily bath time will become a time to check your health. The Mirai Ningen Washing Machine will not only automatically perform all the processes from washing to drying, but will also collect your daily vital signs. In the homes of the future, this data will be useful for health management and early detection of illness.

At "LEBEN Salon Ikebukuro", you can see a demonstration of this "Mirai human washing machine" (can be experienced by making a reservation in advance). After half a century, the "Mirai Human Washing Machine" has evolved from a dream to a reality. Please experience the new daily life of "automatically washing your body and mind" realized by technology.

The relationship between our group and science

Since 2008, our group has been implementing the "Luic Project," developed in collaboration with Science Co., Ltd., as standard in our "LEBEN"condominium brand series, providing homes with a focus on water. The "Luic Project" is our group's original system, and is the collective name for "Takara no Mizu," "Takara no Mirabath Vision," and "Takara no Mirable Shower." "Takara no Mizu" is a water system that purifies all water used in the home. "Takara no Mirabath Vision" is a system that generates microbubbles in the bathtub water, providing cleansing and warming effects with ultra-fine bubbles during daily bathing. "Takara no Mirable Shower" is a system that incorporates ultra-fine bubbles into the water flowing from the shower using a special water flow mechanism. Both systems provide gentle cleansing, moisturizing, and warming effects on the body, and even save water. This allows for more comfortable and economical water use in your daily bathing routine.
