What is [THE ZEN]?

Fire, Earth, Silence.

A sauna experience shaped by nature.

Built by hand. The world’s first earthbag sauna.

A fully self-löyly sauna experience.

Earthbag saunas are built from natural earth-based materials, creating a sauna experience unlike conventional saunas.

The thick earthen walls absorb and gently radiate heat, surrounding your body with a soft, even warmth.

At kakeRu, we call this “round heat”.

Combined with the warmth of wood-fired stones and self-löyly steam, the experience feels somewhere between a traditional sauna and a stone spa.

The temperature is usually around 90-95°C, but with self-loyly, the perceived temperature rises instantly.

The sweating speed is astonishingly fast.

This is one of the saunas currently attracting the most attention in the industry.

Enjoy the new sensation of "Totonoi," the world's first earthbag sauna.

[Reservation Information]

While our sauna is a private facility, there is a possibility that a separate sauna, "KUu," may also be booked at the same time.

In such cases, you may be required to share some common areas, such as the cold bath, toilet, and relaxation area, with other guests.

While we value privacy, we ask for your understanding of the above points.

We appreciate your consideration and cooperation with other guests to ensure a quiet and comfortable stay.
