Shukuba (宿場) were post stations during the Edo period in Japan, generally located on one of the Edo Five Routes or one of its sub-routes. They were also called shuku-eki (宿駅). These post stations were places where travelers could rest on their journey around the nation. They were created based on policies for the transportation of goods by horseback that were developed during the Nara and Heian periods.

The Tōkaidō road , which roughly means "eastern sea route," was the most important of the Five Routes of the Edo period in Japan, connecting Kyoto to Edo. Unlike the inland and less heavily travelled Nakasendō, the Tōkaidō travelled along the sea coast of eastern Honshū, hence the route's name.
