SQUEEZE Inc. (Head Office: Kitahiroshima, Hokkaido; CEO: Shinichi Tatebayashi), in collaboration with ES-CON JAPAN Ltd. (Head Office: Minato-ku, Tokyo; President: Takatoshi Ito) and Science Co., Ltd. (Head Office: Yodogawa-ku, Osaka; President: Yasuhiro Mizukami), has announced the introduction of the next-generation bathing device “Future Human Washing Machine”—which gained attention at the Expo 2025 Osaka, Kansai—at the sauna facilities of “ES CON FIELD HOKKAIDO Hotel Kitahiroshima Ekimae,” operated by SQUEEZE. This marks the first installation of the device in Hokkaido.
General use is scheduled to begin on March 31, 2026 (with reservations opening on March 19). At today’s unveiling event, guests including comedian Kokado from the duo Lotti, former Hokkaido Nippon-Ham Fighters pitcher Yuki Saito, and former Fighters Girl Miyu Takiya participated in a talk session themed around “The Future of Bathing.”
■ Background of Installation at ES CON FIELD HOKKAIDO Hotel Kitahiroshima Ekimae
The hotel was developed by ES-CON JAPAN Ltd. and is operated by SQUEEZE Inc. It features fully private sauna rooms designed to accommodate groups while providing a relaxed and exclusive environment for personal “totonoi” (sauna relaxation experiences).
With the introduction of the “Future Human Washing Machine,” developed by Science Co., Ltd. using its innovative fine bubble technology, the hotel becomes the first in Hokkaido to offer this next-generation bathing experience. By incorporating advanced technology-driven wellness, the initiative aims to create a unique value proposition that goes beyond conventional bathing.
Leveraging the private room concept, guests can enjoy the full sequence of sauna, cold bath, the human washing machine, and outdoor air bathing without concern for others, delivering an unprecedented, ultimate “totonoi routine.”
■ Unveiling Event for the “Future Human Washing Machine” – First Launch in Hokkaido
Today, an unveiling event for the “Future Human Washing Machine” was held at the Live Arena on the 2nd floor of “tonarie Kitahiroshima,” a commercial facility located on the lower floors of the hotel.
At the event, Yasuaki Aoyama, Chairman of Science Holdings Co., Ltd.; Yoshiro Kato, Senior Executive Officer and Head of the Hokkaido Branch at ES-CON JAPAN Ltd.; and Satoki Nakata, Executive Officer at SQUEEZE Inc., took the stage to present the features and usage of the “Future Human Washing Machine,” as well as the background behind its introduction.
Guest speakers included comedian Kokado from the duo Lotti, who experienced the “Future Human Washing Machine” firsthand, as well as Yuki Saito and Miyu Takiya, both closely associated with “ES CON FIELD HOKKAIDO.” They shared their impressions of the device’s futuristic design and advanced technology.
Kokado, who tried the experience, expressed surprise at the technology that cleanses the body using fine bubbles without the need for scrubbing, as well as the soothing sensation of the enveloping warm water mist. His reactions generated significant excitement and engagement among attendees at the venue.
■ About the “Future Human Washing Machine”
Utilizing cutting-edge fine bubble technology, the system enables deep cleansing of impurities within pores simply by immersing the body in water, offering a new bathing experience that does not require scrubbing.
In addition, during use, the system monitors electrocardiographic (ECG) waveforms to analyze the user’s autonomic nervous system condition, and enhances relaxation by projecting tailored music and visual content. This creates a comprehensive wellness experience that supports both physical and mental well-being.
