It is located in the present-day town of Ōiso, located in Naka District, Kanagawa Prefecture, Japan.
Ōiso-juku was established in 1601, along with the other original post stations along the Tōkaidō, by Tokugawa Ieyasu.
In 1604, Ieyasu planted a 3.9 km (2.4 mi) colonnade of pine and hackberry trees, to provide shade for the travelers.
[1] The classic ukiyo-e print by Andō Hiroshige (Hōeidō edition) from 1831–1834 depicts travelers in straw raincoats entering a village by the ocean during pouring rain.
By contrast, the Kyōka edition of the late 1830s depicts a prosperous village overlooking a wide expanse of Sagami Bay with the mountains of the Izu Peninsula on the far shore.
