History
Shadai Station began on 1907-12-25 as the Shadai signal post of the Imperial Railway Agency. It was promoted to a freight station — Shadai Station — on 1909-10-15, and started carrying passengers and parcels on 1917-06-01. Freight handling ended on 1961-09-29, parcels on 1980-05-15, and the station was unstaffed under simple commission from the same day. A new building replaced the previous one in January 1981, the simple commission lapsed on 1984-04-01, and JR Hokkaido inherited the now fully unstaffed station at the 1987 privatisation. The station has a single island platform serving two tracks; a side-line on the down side once doubled as a bidirectional siding around 1983.

Notes
From Shadai eastward to just before Numanohata, the Muroran Main Line runs perfectly straight for 28.7 km — one of the longest straight stretches of conventional railway in Japan.
