History
Minami-Otaru Station traces its origins to Kaiunchō Station, an intermediate stop on the Horonai Railway that opened provisionally on 11 November 1880 and formally on 28 November of the same year. After fire destroyed the original building, the station was relocated and reopened as Sumiyoshi Station on 22 May 1881. It was renamed Otaru Station on 11 June 1900, and adopted its present name Minami-Otaru on 15 July 1920 when the former Chūō Otaru Station — closer to the city centre — assumed the name Otaru. On 1 August 1905 the station became a junction between the Hokkaido Colliery and Railway lines (the former Horonai Railway) and the Hokkaido Railway. After the nationalisation of both private companies, the Hakodate Main Line was designated as the trunk route via Otaru and the branch westward to Temiya became the Temiya Line; that branch was abolished in 1985.

Notes
Although Minami-Otaru is firmly within Otaru's urban fabric today, in name it carries the city's identity at one remove — the station bore the name "Otaru" itself for the first two decades of the twentieth century, before the more central Chūō Otaru took over the title in 1920.
