History
Kami-Oboro Station opened on 1917-12-01 as a general station when the Imperial Railway Bureau extended the Kushiro Main Line (now the Nemuro Main Line) east from Kushiro to Hama-Akkeshi. Forestry and coal mining made the area prosperous, and several private tramways once fed coal and ore to the station's loading bays: a 4.5 km trolley line from the Yachiyo Mine around 1918, and 3 km–5 km horse tramways from the Mitsuboshi and Aoba mines around 1933. The 1943 wartime small-mine consolidation order closed them all. The current station building dates from December 1935. Freight handling ended on 1974-10-01, parcels on 1984-02-01, and the station was unstaffed from 1986-11-01. JR Hokkaido took over at the 1987 privatisation.
