Kousyu Kaido

In Edo era, Kousyu Kaido was used to be one of 5 main trails. Edo government ordered local lords to come to see Edo Syogun once a year. These roads were needed for their transportations between Edo and local areas.
The end of the Kousyu-kaido was Koufu, and another trail started from Koufu.
