• Yokosuka Line: Taura ⇄ Kinugasa

Yokosuka Station opened on 16 June 1889 as the original terminus of a JGR spur from Ōfuna built to serve the Yokosuka Naval Arsenal and the Imperial Japanese Navy. The spur was reclassified as the Yokosuka Line on 12 October 1909. The third and current station building was completed in April 1940, and the line was extended south to Kurihama in 1944. Freight operations were retained for US Navy supply duties post-war but formally ended on 1 February 1984. Operation passed to JR East at the 1987 JNR privatisation, and Suica IC fares began on 18 November 2001. The station was named one of Kantō's Top-100 Stations in 1997 for its rare entirely step-free layout.

Because platform 2 is a dead-end bay platform used by trains that turn back at Yokosuka, no footbridge is needed and the station has no stairs anywhere inside it; its station stamp once carried the legend 'the station with no stairs'.
