Drinking SpringAbout
Yoro Onsen Main Building is a small, no-frills ryokan with one indoor bath each for men and women, each with a slightly deeper section in the middle. The spring water is radon-bearing, drawn cold and warmed before use, and there are drinking fountains for it near the bath entrances. The inn sits in the mountains, with a view of the river. Day-use bathing includes a rest hall where a meal can be had.
