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.

In July 1965 the Sōya Main Line between the former Kami-Onoppunai Station and Onoppunai was rerouted onto a new 2.4 km alignment through the Shimohira Tunnel, leaving the old Shimohira viaduct disused; Horonobe Town later bought part of the abandoned line and converted it into the Shimohira Bridge on town road Yūkō No. 1, a road link to the Tantashamonai district.
