It is located in the present-day city of Ōgaki, Gifu Prefecture, Japan.

In addition to serving as a post station, it was also a castle town to the Ōgaki Domain's Ōgaki Castle.

Its dual role is very similar to that of the nearby Kanō-juku along the Nakasendō.

Ōgaki stretched approximately 2.9 km (1.8 mi) from west to east, though its main gates were only 1.1 km (0.7 mi) apart.

The location of the former post station can be traced along the Tenma-chō, Hon-machi, Takejima-chō, Tawara-machi, Funa-machi, and Kusegawa-chō areas of the city.
