An onsen (温泉) is a Japanese hot spring. The open-air variety is the kind usually seen in anime, but there are indoor ones as well.
Bathing areas are often dived into women's and men's, although there are unisex exceptions.
The following tags are aliased to this tag: hot_springs, hot_spring, and hotspring (learn more).
