Kamiiso

Departure data for this station is not available on this site.

Kamiiso Station opened on 15 September 1913 with the Government Railways' new Kamiiso Light Railway Line between Goryōkaku and the station. In 1915 a private cement-works line to the plant of Nihon Cement (now Taiheiyō Cement) began operating from the site, and the route was renamed the Esashi Line in 1936. With the JNR split on 1 April 1987 the station passed to JR Hokkaido; the section was electrified in 1988, and the station was rebuilt at the same time with an overhead station building spanning the tracks. On 26 March 2016, when the Hokkaidō Shinkansen opened, JR Hokkaido transferred the Goryōkaku–Kikonai segment to the South Hokkaido Railway Company, and Kamiiso became an unstaffed stop on the renamed Dōnan Isaribi Railway Line.

Two explanations are given for the place name: an Ainu kama-iso, meaning rocks washed over by waves, and a Hokkaidō usage in which the west was called kami, the upper — this being the iso, the rocky shore, lying west of Hakodate.
