History
Onoppunai Station opened on 20 July 1925 with the Japanese Government Railways Teshio South Line extension between Toikanbetsu and Horonobe. The line was renamed the Teshio Line in 1926 and absorbed into the Soya Main Line on 1 April 1930. A wooden replacement building was raised in November 1953. Freight ended in 1982; the station was unstaffed from 10 November 1984, and JR Hokkaido took it on at the 1987 privatisation. From April 2021 Horonobe Town funded upkeep, citing the wooden depot's rarity. When 5-million-yen repairs came due, the town withdrew support, and on 15 March 2025 passenger service ended and the site was demoted to Onoppunai Signal Box; the building was demolished later that year.

Notes
The 1965 Soya Main Line realignment that bypassed Onoppunai created the Shimohira Bridge, a former rail bridge later repurposed by Horonobe Town as a road link to the isolated Tantashamonai district.
