The Tokaido road was fully developed in the Edo period (1603 – 1868) as the main route linking Kyoto (the de jure capital of Japan) to Edo (the de facto capital, modern day Tokyo). It flourished thanks to the constant flow of travelers, especially daimyo processions (feudal lords and their entourage, who were required to spend every other year living in Edo). Shizuoka City is the location of two mountain passes said to be difficult parts of the Tokaido road: Satta Pass and Utsunoya Pass. It is also the location of six post towns: Kanbara, Yui, Okitsu, Ejiri, Fuchu, and Mariko. Along with beautiful views of Mt. Fuji, unique traces of remnants and reminders of the Tokaido road, which was once beloved by many travelers, still remain here and there.
