History
Nanaehama Station opened on 1926-06-21 as a passenger stop on the Japanese Government Railways Kamiiso Line, picking up freight handling in 1933 before that became its main role serving the adjacent North Japan Oil (北日本石油, later Cosmo Oil) Hakodate refinery from 1956. The line was renamed Esashi in 1936, and the station's wooden building was replaced in 1979 and then by an elevated overhead structure in 1986. JR Hokkaido took it over at the 1987 privatisation, freight ended in 1984, and on 2016-03-26 the Goryōkaku–Kikonai section transferred to the South Hokkaido Railway Company, leaving the station unattended on the renamed Isaribi Line.
