History
Kai-Ōizumi Station opened on 27 July 1933, on the day the Japanese Government Railways completed the Koumi Line section between Kobuchizawa and Kiyosato. Located in Ōizumi-Nishiide in Hokuto, Yamanashi Prefecture, on the southern slopes of Mount Yatsugatake, it sits at 1,158 m above sea level. Freight handling ended on 1 February 1963, parcel handling on 1 October 1970 — when the station became unstaffed under a simplified contract — and with the privatisation of JNR on 1 April 1987 the station came under JR East. It joined the Tokyo Suburban Area on 1 April 2014, and the simplified contract was dissolved on 26 March 2023, leaving the station fully unstaffed. The station has two opposed side platforms.
