ForestAbout
A single indoor bath fed by a spring from 500 meters underground, with milky white water that leaves the skin smooth. There is also a sauna, a cold bath, and a small outdoor air space. The building has a relaxed, Showa-era health-center feel, with a cafeteria, rest area, and gift corner all under one roof.
