History
Jōko Station opened on 10 March 1899 as Yamagata Station (山潟駅) of the private Iwakoshi Railway, then serving as the terminus from the Kōriyama direction; the line was extended to Wakamatsu on 15 July of the same year. Iwakoshi Railway was nationalised on 1 November 1906, and the station was renamed Jōko on 1 June 1915. Freight handling ended in September 1972, and CTC introduction on the Ban'etsu West Line in March 1983 made the station unstaffed; the current station building dates from that period. With JNR privatisation on 1 April 1987 the station passed to JR East. The down track was subsequently removed and the station became single-tracked.
