Onna Village, Okinawa.
In this land where the forest and the sea meet and myths breathe,
There is one answer to renew the concept of sauna.
The core of the structure is "soil".
A natural material that wraps up the heat and slowly releases it.
The gentleness of the bedrock bath and the strength of the sauna.
A deep and quiet heat experience that was born in the meantime.
The world's first earthbag sauna [THE ZEN]

A new earthbag sauna [KUu] evolved from there.

This is the only place in the world where two beings coexist
There is a blue swaying sea in front of you, and a quiet forest behind you.
Ever-changing natural expressions and wind, sounds, and scents
The extraordinary that you can feel with all five senses is an overwhelming retreat experience.
