The indoor bath in the public bath lets you enjoy the very rare Shirahata Spring, which has the longest history in Kusatsu, rises just beside Yubatake, and is piped only to a limited number of inns. It contains an exceptionally rich sulfur content and is characterized by its softly cloudy, milky-white water. The pleasant scent of sulfur fills the bath, and in the newly built spacious tubs with different temperature settings, you can slowly savor the warmth of a famed spring that seems to gently cling to the skin.

Flowing into the open, garden-style open-air bath Ishitei is Bandai Kosen Spring, the geothermal spring overflowing with the earth’s energy, boasting the highest source temperature and strongest acidity in Kusatsu Onsen. It is colorless and clear, with a stimulating feel that is more acidic than lemon water. Known for its powerful antibacterial properties and excellent peeling effect that helps remove old dead skin, it offers the chance to enjoy a premium free-flowing open-air bath while admiring the changing beauty of the four seasons.
