Hotel hospitality to travellers have been a feature of the earliest civilizations. In Greco-Roman culture and ancient Persia, hospitals for recuperation and rest were built at thermal baths. Japan's Nishiyama Onsen Keiunkan, founded in 705, was officially recognised by the Guinness World Records as the oldest hotel in the world.

Bathing stations are equipped with stools, faucets, wooden buckets, and toiletries such as soap and shampoo; nearly all onsen also provide removable shower heads for bathing convenience. Entering the onsen while still dirty or with traces of soap on the body is socially unacceptable. Bathers
