Enjoy a restful and relaxing experience with beautiful seasonal scenery, as you soak in the outdoor bath.

The public bath located on the second floor of The Westin Rusutsu Resort uses natural spring water from the foot of Mt. Yotei. This high-quality natural spring water is naturally filtered over several decades from the snow accumulated on Hokkaido's famous Mt. Yotei, located in the center of Shikotsu-Toya National Park. This natural water has previously been selected as one of the “top 100 waters in Japan”.

The soft, mild and faintly alkaline natural spring water gently envelopes your body and soul in a warm embrace.

This water is also used for drinking water in the restaurant and in guest rooms earning high praise from customers for its delicious flavor. Be sure to quench your thirst and unwind with a smooth glass of delicious water after a relaxing soak in the large public bath.
