Tokoro River Hot Spring
A private hot spring sourced by drilling approximately 1,200 meters on the hotel premises. The alkaline water with a pH of 9.4 has a slightly viscous feel, gently removing old keratin and leaving the skin smooth. The water is heated to an appropriate temperature, thoroughly warming the body to the core. The warmth continues long after bathing, making it difficult to catch a chill even in the winter of Okhotsk. An open-air bath is also available, allowing guests to enjoy the hot spring while feeling the clear air of Hokkaido.
