During the Edo period it became a peaceful time, and the Go-Kaido Road (the five major roads starting from Edo - present day Tokyo), Wakiokan (main roads other than the roads included in the Go-Kaido) and post station towns were improved nationwide for civilian travelers and feudal lords traveling for Sankinkotai (a system during the Edo period which required feudal lords to spend every other year residing in Edo).
江戸時代となり、平和な時代になると、一般旅行者や諸大名の参勤交代のために五街道や脇往還、宿場町が日本全国で整備された。
