MountainsAbout
A day-use bath in a wooded part of Karuizawa, run by the Prince Hotels resort nearby. The outdoor garden baths flow on spring water straight from the source, and the covered rotenburo alongside them does too. The large indoor hall has wide windows onto the surrounding trees and hills. There is also a Finnish sauna and a cold plunge. It tends to be quiet and uncrowded, especially on weekdays.
