53 Stations of the Tōkaidō
The 53 Stations of the Tōkaidō (東海道五十三次, Tōkaidō Gojūsan-tsugi) are the rest areas along the Tōkaidō, which was a coastal route that ran from Nihonbashi in Edo (modern-day Tokyo) to Sanjō Ōhashi in Kyoto. There were originally 53 government post stations along the Tōkaidō, where travelers had to present traveling permits at each station if wanting to cross.
