What's "touji"?

Why do we go to onsens?

but our heart and body.

Ever since the beginning, a way of using onsens called "touji" exists in Japan.
Bathing in "touji" waters, healing the body, cleansing the body, clearing the heart and mind.
Experiencing something out of everyday life,
detaching the accumulated stress of everyday life from your mind and body, then washing it off.

That is acheived by hot water, food, and company.

By combining all of them,
and wrapping your body in it,
you will have the power to walk forward towards tomorrow.

Let us bring you the special journey your mind and body needed.
