Onsen HopperOutdoor onsen in Japan
737 day-use onsen with an outdoor bath, a rotenburo, open to visitors who are not staying the night.
Outdoor means the official site lists a rotenburo or open-air bath. Some are a single tub on a terrace, some a riverside pool; the listing's own text says which where the site does. Updated 2026-10-18.
