History.
Ochiai-juku is separated from Magome-juku to the east by the Jikkoku Pass, which marked the informal border of the "Kiso Kaido" portion of the Nakasendō highway In the early Edo period, the system of post stations on the Nakasendō was formalized by the Tokugawa shogunate in 1602, and it became a stopping place for traveling merchants () and it was also on the "sankin-kōtai" route used by various western "daimyō" to-and-from the Shogun's court in Edo. 
Per the 1843 guidebook issued by the , the town had a population of 370 people in 75 houses, including one "honjin", one "waki-honjin," and 14 "hatago". The post station was located within Owari Domain, and was 331.2 kilometers from Edo.
The post station remains very well preserved, and unusually, both the "honjin" and "waki-honjin" have survived.

Utagawa Hiroshige's "ukiyo-e" print of Ochiai-juku dates from 1835 -1838. The print depicts a "daimyō" procession departing Ochiai-juku across a rustic bridge. The "daimyō" is riding in a closed "kago" (palanquin), with a long straggling line of retainers in front and in back, some of whom are carrying his luggage. In the background is the post station, behind which are the high peaks of the Ena Mountains, indicating that the procession is heading towards home in the west.
