BlueOcean was created as an immersive sauna resort that transcends the traditional boundaries of “saunas” and “super sentos,” blending visuals, light, sound, water, and scent.

It’s not just about “rejuvenation.”

The entire facility becomes a form of entertainment, offering an unprecedented experience where you can enjoy new discoveries and excitement every time you visit.

■ A New Sauna Experience That Engages All Five Senses

We’ve installed numerous projection mapping displays and large LED screens throughout the facility, transforming the entire space into a fantastical world.

From the fantastical reception area recreating an underwater world to the hot stone bath inspired by a sea of clouds, and from the video sauna where light and music merge to special event hot stone baths, we’ve created spaces brimming with immersion unlike anything found in traditional thermal bath facilities.

It is a “stay-and-experience entertainment facility” where you can enjoy a different atmosphere every time you visit.

Blue Ocean Opening

■ The decision to postpone the opening was made to create an even better facility

We have postponed the opening of this facility from its originally scheduled date.

The reason for this was that we thoroughly reviewed our facilities, operational structure, and service offerings from the ground up to provide our guests with safe, secure, and higher-quality services.

To live up to the expectations of everyone who has been eagerly awaiting our opening, we have paid meticulous attention to every detail and are now ready to celebrate our grand opening.

■ A Facility That Grows Alongside the Community

BlueOcean is actively committed to collaborating with the local community.

As a new hub for tourism and visitor attraction in the Shin-Yokohama area, we aim to contribute to the revitalization of the local economy while creating a facility that is loved by many guests.

We will continue to actively develop new events and initiatives, and we are committed to the ongoing challenge of ensuring this remains a place where visitors say, “I want to come back.”
