Our 3 Promises

A sanctuary of silence, reserved just for you.

Enjoy our exclusive private booking style.

> No crowds, no distractions—

only the sound of your own breath, > the crackling of the firewood, and the whisper of the wind.

> Strip away the noise of daily life and rediscover true freedom in total relaxation.

A gentle stream where everyone can play.

The crystal-clear Yokowa River flows right before your eyes, so pure that fireflies dance here in summer.

It is not a deep or rushing river,

making it a gentle and safe place for small children and pets to splash and play.

Here, you will find a peaceful scene of “totonoi,” where every member of the family can smile together.

More than a sauna—a place for everyone to belong.

Whether you are a sauna enthusiast or just seeking a getaway, there is something for everyone.

After cooling off in the river, run through the garden with your dog or simply lounge indoors in total comfort.

We may not be a large resort, but this entire space is your very own “private playground” to explore.
