Tagajō Station opened on 5 June 1925 as part of the Miyagi Electric Railway's initial Sendai–Nishi-Shiogama section. The line was nationalised on 1 May 1944, and the station handled freight until October 1971 and parcels until February 1984. It passed to JR East at the privatisation of Japanese National Railways on 1 April 1987. From fiscal 1999 a continuous grade-separation project costing roughly 12.8 billion yen was carried out at and around the station, covering a 1.8-kilometre stretch through it and eliminating four level crossings; the up-line was switched to elevated track on 29 November 2009, the down-line on 8 April 2012, and the rebuilt three-track elevated station and new building entered service on 17 November 2013.

During the elevation construction work, trains could not turn back at this station, and until 14 March 2014 they continued to be run empty to Higashi-Shiogama Station to turn back there.
