Koga Station opened on 16 July 1885 as part of Nippon Railway's Ōmiya-Utsunomiya extension and is the first railway station ever established in Ibaraki Prefecture. The Tone River bridge had yet to be built, so passengers were carried by ferry between Kurihashi and a temporary Nakada halt until the bridge was completed. Nippon Railway was nationalised in November 1906, and the station was reclassified as a Tōhoku Main Line stop in October 1909. The tracks through the station were elevated in stages between 1983 and 1984, the existing station building under the viaduct opened on 24 March 1984, and the property passed to JR East at the 1987 privatisation.

An iron pavilion in the centre of the east-side plaza is built from the columns of the old surface-level pedestrian footbridge, kept as a memento after the line was elevated in 1984.
