A New Era for ONESEN & SAUNA RESORT Kaihotsu

On August 3, 2026, the ONESEN & SAUNA RESORT Kaihotsu, a rejuvenated hot spring facility located in Fukui City, reopened its doors, introducing the innovative UFB DUAL® ultra-fine bubble generating nozzles. Managed by U企画 Co., Ltd., the facility has a rich history of over three decades and has now transitioned to become a part of the 越のゆ Group, renowned for its expansive thermal facilities across Fukui Prefecture and beyond.

The relaunch of this beloved venue follows an extensive three-month renovation from May 2026, completely modernizing the health-promoting complex while maintaining its community resort charm. Upon reopening, visitors can explore a serene, Nordic-inspired relaxation area, a spacious large bath featuring a newly installed high-concentration carbonated spring, and an updated dining venue renamed '越前旬味 かいほつダイニング'. A new 'Cafe & Bar ゆるり' has also been introduced on the third floor, further enhancing the guest experience.

UFB DUAL® Installation - A Leap in Wellness

A significant upgrade in this facility is the installation of the UFB DUAL®, a unique ultra-fine bubble generation nozzle directly connected to the water supply systems. Unlike traditional individual nozzle products, the UFB DUAL® provides ultra-fine bubble water throughout the entire establishment. A 100A model has been installed in the main water supply, while a dedicated 65A unit supports the new carbonated spring system.

This technology ensures that ultra-fine bubble water benefits various areas of the facility, including showers, washbasins, kitchens, toilets, and for routine sanitation. Not only does this support an enjoyable bathing experience, but it also enhances hygiene management throughout the entire facility's plumbing infrastructure.

Experience the Benefits of High-Concentration Carbonated Spring

The facility proudly introduces high-concentration carbonated baths which dissolve carbon dioxide in water to create a refreshing soak. Proper management of circulation flow, temperatures, and gas supply is crucial to maintain stable carbonation levels. The installation of a UFB DUAL® unit ensures efficient interaction between carbon dioxide and water, promoting the formation of delicate bubbles and optimizing the use of gas resources. In an age of rising operational costs for thermal facilities, the goal is to maintain the allure of high-concentration carbonated baths while controlling gas consumption and running costs.

Enhancing Hygiene Management

Endorsed by the Japan Water Utilization Facility Environmental Hygiene Association, UFB DUAL® plays an essential role in sanitation. Biofilms can accumulate in plumbing and filtration systems, posing health risks. Regular removal and disinfection of these biofilms are crucial to prevent contamination. The UFB DUAL® aids in detaching and removing these films, creating a challenging environment for harmful bacteria like Legionella. Continuous flow of ultra-fine bubble water during regular usage helps maintain hygiene in plumbing and sanitation effectively.

Looking Forward

Facility representatives expressed their commitment to utilizing the UFB DUAL® system for both the high-concentration carbonated spring and general water supply throughout the establishment. Monitoring guest feedback, cleaning processes, and operation of the carbon dioxide systems will be pivotal in evaluating the effectiveness of these enhancements.

The ONESEN & SAUNA RESORT Kaihotsu aims not just to delight visitors with fine bathing experiences but also ensures a clean and safe environment through innovative water solutions. As the gender-neutral sauna 'サウナガーデン Moi' is set to launch in early September 2026, guests can look forward to a holistic wellness haven that merges tradition with modern technology.
