A ryokan is a type of traditional Japanese inn that typically features tatami-matted rooms, communal baths, and other public areas where visitors may wear nemaki and talk with the owner. Ryokan have existed since the eighth century A.D. during the Keiun period, which is when the oldest hotel in the world, Nishiyama Onsen Keiunkan, was created in 705 A.D. Another old ryokan called Hōshi Ryokan was founded in 718 A.D. and was also known as the world's second oldest hotel. Such inns also served travelers along Japan's highways.

Inns are generally establishments or buildings where travelers can seek lodging, and usually, food and drink. Inns are typically located in the country or along a highway. Before the advent of motorized transportation, they also provided accommodation for horses.
