Black Silica Bath
A gentle-on-the-skin bath infused with rare black silica, which can only be quarried in Kaminokuni Town, Hokkaido. It uses groundwater pumped from 150 meters underground and heated for bathing, offering a mellow water quality with dissolved active minerals. The indoor baths are rich in variety, including reclining baths, seated baths, powerful jet baths, and electric baths, while the open-air stone bath is spacious and refreshing. You can relax at the waterfall bath or on chairs in the semi-indoor bath area.
