The river, whose name means "Frozen Dark One", was named after Mieji-juku, the 56th post town on the Nakasendō, a historical trading route.

[1] The river flows south from the southwestern portion of Motosu, crossing over the former Nakasendō and the current Tōkaidō Main Line before reaching Ōgaki.

The river passes through or forms the boundary of Motosu, Hozumi, and Ōgaki, all in Gifu Prefecture.
