"Hiratanaisou" is a hot spring lodging facility in the Kumaishi district of Yakumo, Hokkaido. The "Awabi no Yu" that wells up in this area, which once flourished as the "Awabi Village," is a natural sodium chloride spring that warms the body from the inside out and is said to help relieve fatigue and promote beautiful skin. In the large bath, along with a spacious main tub, there is also an open-air bath and a jacuzzi, except during the winter season. The sauna is a proper dry sauna with intense heat, encouraging a pleasant sweat. After cooling down in the cold plunge bath, you can spend a relaxing moment for both body and mind while feeling the fresh air of Yakumo.
