History
Shioiri Station opened on 1 April 1930 as Yokosuka-Gunkō ('Yokosuka Naval Port') Station on the Shōnan Electric Railway, with the name renamed Yokosuka-Shiodome on 1 October 1940 for wartime concealment. Following the 1941 merger with Keihin Electric Railway and the 1942 Tokyu period, Keikyu took over in 1948. The stop was given its present name, drawn from the surrounding Shioiri neighbourhood, on 1 September 1961, the same year that the on-platform crossing was replaced by an underpass and the platforms were lengthened to six cars. A barrier-free retrofit completed on 23 December 1994 added an elevator and a free pedestrian passage, and the line's first lightweight platform doors went into use on 23 April 2022.

Notes
The platform doors installed in April 2022 were Keikyu's first lightweight type, developed by Ongakukan and previously used on JR Kyushu.
