Sento (銭湯) are Japanese public bathhouses using heated municipal water, as opposed to natural hot spring water. The name means "coin hot water."
History
Sento have been part of Japanese urban life for centuries:
- Originally essential for hygiene (few homes had baths)
- Social gathering places
- Neighbourhood institutions
Today they're less common but still culturally significant.
