Highlights
Drinking Spring
Lukewarm BathAbout
A small, old-fashioned bathhouse near the top of Mount Yoshozan, with just one indoor tub and no rotenburo or sauna. The natural radon spring water feels soft and faintly viscous, kept at a gentle, lukewarm temperature that invites a long soak rather than a quick dip. A coin-operated stand outside lets you take the cold spring water home to drink. It's a plain, quiet spot, not a big resort facility, and the drive up the mountain has good views along the way.
