A wellness resort for grown-ups,
filled with the bliss of the seaside
About 90 minutes by car from Tokyo.
The sound of waves rolling in. The sea breeze blowing through. A private sauna resort for grown-ups, where you enjoy authentic aroma löyly in front of the quiet, shallow Motona Beach of Minamiboso.
A cold bath fed by spring water from Mt. Nokogiri. A “totonou” spot with a beautiful view of Mt. Fuji across Tokyo Bay. After the sauna, raise a glass to a beautiful sunset at the panoramic cafe.
The ultimate “totonou”, a gift from the beachside hot-spring resort Yuumi to every sauna lover who loves the sea, is here.

About the Beach Sauna

01
The ultimate “totonou”, facing the sea
A special sauna experience in front of the white sands of Motona Beach, wrapped in the sound of the waves and the sea breeze. Here is time to leave the everyday behind and become one with nature.

02
Deep relaxation with aroma löyly
What we pour over the sauna stones is fragrant aroma water. Together with the fresh seaside air, enjoy an elegant löyly experience that loosens body and mind.

03
A cold bath of Mt. Nokogiri spring water, and a dive into the sea
After the sauna, step into a cold bath of clear spring water that wells up from Mt. Nokogiri. Then, if you like, plunge straight into the beach in front of you and feel the freedom of the sea with your whole body. A luxurious cool-down style found only here, bathing in nature's bounty.

04
An open-air rest that feels the sea and sky
The sea spreading out before you, a sky coloured by dusk, a pleasant sea breeze. An open-air rest bathed in scenery woven by nature can be experienced only here.
