Main bathhouse
Separate main bathhouses for men and women, facing the Five Peaks of Aso head-on. Each has an indoor bath and an open-air bath opening wide toward the mountains, and the open-air area also has a ceramic urn bath. The water is a natural alkaline simple spring, prized for its soft feel that leaves the skin smooth. It is also said to be good for neuralgia, muscle pain, joint pain and sensitivity to cold. Time spent sinking into the water while gazing at green mountainsides in the highland breeze by day and a sky thick with stars by night quietly eases away the fatigue of travel.
