History
Ōiso Station opened on 11 July 1887 on the Tōkaidō Main Line of the Japanese Government Railways, then a brand-new section between the old Yokohama Station and Kōzu. The stop was not part of the original route plan; it was added after the physician Matsumoto Ryōjun lobbied for a station to support a new seaside-bathing resort. Freight traffic ended in 1962 and parcel handling in 1972. Operation passed to JR East at the privatisation of the Japanese National Railways on 1 April 1987. Suica IC fare gates were introduced on 18 November 2001, and the Midori no Madoguchi ticket office closed in September 2021.
Notes
The station was added to the Tōkaidō Main Line only after physician Matsumoto Ryōjun lobbied for a stop to support his nearby sea-bathing resort.
