History
Kōma Station opened on 1 September 1891 as a Nippon Railway stop serving Tamayama village in present-day Morioka. It became a government station with the line's nationalisation in November 1906, and gained a junction role on 27 August 1922 when the Hanawa Line was completed. Freight handling ended in November 1978 and parcel handling in March 1985 before JR privatisation transferred the station to JR East on 1 April 1987. With the Tohoku Shinkansen's Hachinohe extension on 1 December 2002, the Morioka-Metoki portion of the Tōhoku Main Line passed to IGR Iwate Galaxy Railway, and Kōma became a joint-use station under IGR management. A bridge-style building with east-west free passage opened on 15 May 2011.

Notes
Poet Ishikawa Takuboku boarded a Tokyo-bound train at Kōma when leaving his home village; Shibutami Station, today's nearest stop to his birthplace, did not yet exist.
