The historic city of Mito in Ibaraki Prefecture serves as the transfer point to the JR Suigun Line, a narrow-gauge single-track line that runs along the scenic Kuji River en route to the Fukuroda Falls.

Known as Oku Kuji (Upper Kuji), it's a lovely pastoral area at the northeastern extremity of the Kanto region.

The Suigun Line plays hide and seek with National Highway 118, which crosses and re-crosses the Kuji River as it meanders through the hills.
