History
Oshamambe Station opened on 1903-11-03 as a stop on the privately operated Hokkaido Railway, which was nationalised in 1907. On 1923-12-10 the state-run Chōrin Line opened east from the station toward Shizukari, and that line was later integrated into the Muroran Main Line on 1931-04-01, giving Oshamambe its current role as a junction between the Hakodate Main Line and Muroran Main Line. The station served as a major railway hub during the JNR era — Oshamambe Depot existed here from 1928 — and control passed to JR Hokkaido on 1987-04-01. It is also planned as a station on the Hokkaido Shinkansen extension between Shin-Yakumo and Kutchan, scheduled to open in 2031.

Notes
Oshamambe's longstanding ekiben "Kanaya no Kanimeshi" was sold from platform vendors from 1950 onward and was eventually loaded into limited expresses by onboard staff, before the 2019 end of in-train sales on the Super Hokuto effectively closed the platform's role for it.
