History
Toasa Station opened on 1902-09-21 as a general station of the private Hokkaido Colliery Railway between Numanohata and Hayakita. The original plan had been to build the station roughly 700 m south on higher ground, but residents successfully lobbied for the current location. The line was nationalised on 1906-10-01 and became the Muroran Main Line on 1909-10-12. A second station building replaced the original in 1923, platforms were rebuilt in 1953, and the present third-generation building opened in January 1981. Freight handling ended on 1972-03-16, parcels on 1980-05-15, and the station was unstaffed from that date under a simple commission, which itself lapsed at an unrecorded later date. JR Hokkaido inherited the station at the 1987 privatisation, and the layout was reduced to a simple bidirectional through line under Otoshibe-controlled signalling on 1981-11-02.

Notes
The current building, in use since January 1981, is a near-twin of the Kojōhama Station building elsewhere on the Muroran Line; the only obvious difference is Toasa's maroon-coloured gable ends.
