History
Kai-Ōshima Station opened on 8 April 1919 as the temporary terminus of the privately operated Fuji-Minobu Railway when the line was extended north from Nanbu-Utsubuna, in present-day Minobu, Yamanashi Prefecture. On 18 May 1920 the line was extended to Minobu and the station became an intermediate stop. The Ministry of Railways leased the Fuji-Minobu Railway from 1 October 1938 and nationalised the line on 1 May 1941, when the station joined the Minobu Line. Parcel handling ceased on 20 September 1972, freight services ended on 1 April 1978, and the station was destaffed on 1 June 1983. JR Central took over on 1 April 1987, and the current second-generation station building was completed in February 2000.
