Kamiiso

No publicly available departure data for this station.

Kamiiso Station opened on 15 September 1913 with the Government Railways' new Kamiiso Light Railway between Goryōkaku and the station. In 1915 a private cement-works line to Nihon Cement (now Taiheiyō Cement) began using 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 remodelled as a footbridge station. 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 Donan Isaribi Railway Line.

Two readings explain the place name: an Ainu kama-iso meaning rocks washed by waves, and a Hokkaidō convention that called the western shore of Hakodate kami, the upper, magnified by the rocky iso coastline.
