What is [KUu]?

In a space where heat and silence intertwine, you can release your mind and body and experience the sensation of simply being present in the here and now.

The sauna's heat and steam melt away the stress and distractions of everyday life,

and you can experience the moment when your mind becomes empty in a state of deep peace and harmony.

The evolved Earthbag Sauna is complete!

Supervised by madsaunist, Saunner of the Year 2024.

By incorporating a steam generator, the sauna creates an exquisite ensemble of two types of steam (saturated steam and heated steam) and

three types of heat waves (radiant heat from MAD STONE and Finnish sauna stones,

plus the stored heat of the Earthbag itself), resulting in faster initial sweating and more intense perspiration.

By constantly supplying the necessary amount of scientifically calculated fresh air, breathing inside the sauna is incredibly easy.

Enjoy a new steam bath experience that's "hot, humid, and easy to breathe."

You can also enjoy a "Kneipp" (chilled shower) in the sauna.

Exclusively for private guests, we offer a complimentary "subzero Kneipp" in the last 30 minutes of the day.

When you reach your limit, cool down in a cold water bath chilled by madsaunist's chiller, which is capable of generating ice.

A world of ultimate relaxation awaits you there.

Here is the ultimate sauna you've never known before.

This facility offers private saunas, but please note that we may also receive reservations for "THE ZEN," a separate building, during the same time slot. In such cases, you may be required to share some common areas, such as the cold bath, toilet, and relaxation area, with other guests.

If you wish to reserve the entire facility, including the shared spaces, you will need to make reservations for both buildings.
