History
Hirayama Station opened on 25 March 1936 with the extension of the Kururi Line from Kururi to Kazusa-Kameyama in present-day Kimitsu, Chiba Prefecture. The same Kururi - Kazusa-Kameyama segment was suspended from 16 December 1944 through wartime cutbacks, with Hirayama reopening on 1 July 1947. Parcel handling was discontinued and the station destaffed on 16 September 1954. The current station building came into use in April 1982. With the privatisation of Japanese National Railways on 1 April 1987, operations passed to JR East. Hirayama was incorporated into JR East's Tokyo Suburban Area network on 14 March 2009. The Kururi - Kazusa-Kameyama segment is scheduled to close on 1 April 2027, at which point Hirayama will be abolished.
