History
Kuromatsunai Station opened on 1903-11-03 as a general station of the private Hokkaido Railway when the Mori–Nepu section was completed; a locomotive shed was set up at the same time. After the railway's nationalisation in July 1907, the line became part of the Hakodate Main Line in October 1909. From 1920-10-24 to 1968 the station was the junction with the private Suttsu Railway, which was formally retired on 1972-05-11. The building was rebuilt in January 1980. Freight handling ended on 1982-03-01, parcels on 1985-03-14. JR Hokkaido inherited the station at the 1987 privatisation. The Kuromatsunai stationmaster post was abolished on 2002-04-01 and merged into Oshamambe, and the station was fully unstaffed from 2007-04-01.

Notes
After the Hokkaido Shinkansen extension to Sapporo opens, the parallel Hakodate Main Line section through Kuromatsunai is slated for abolition along with the station itself.
