Station layout A single side platform, located on the waterfront of Tokyo Bay, serves one line for both inbound and outbound trains. The exit is located opposite the buffer stop, with simplified Suica terminals and a ticket disposal box. There is also an automatic ticket machine. Platform Service Umi-Shibaura is served hourly during off-peak times (midday, night and weekends), with more frequent services during morning and evening rush hours. History Umi-Shibaura Station was opened on 1 November 1940 as a station on a spur line of the privately held . The Tsurumi Rinkō line was nationalized on 1 July 1943, and was later absorbed into the Japanese National Railways (JNR) network. The station has been unstaffed since 1 March 1971, although the adjacent Toshiba guardhouse is staffed 24 hours a day. Following the privatization of JNR on 1 April 1987, the station was transferred to operation by JR East. In 2000, Umi-Shibaura Station was selected as one of the top 100 stations in the Kantō region by a public poll conducted by the Ministry of Land, Infrastructure, Transport and Tourism. Surrounding area Toshiba owns the land beneath the station and the surrounding portion of the Tsurumi Line, and JR East operates both under a long-term lease. Because of the surrounding scenery, and its status as "the station which you can never leave", Umi-Shibaura has been featured in several books and television programs and has gained some popularity as a day-trip destination. Toshiba has catered to these tourists by constructing a small park (Shibaura Park) within the station for employees and waiting passengers; it is open to the public (during business hours) and has a sweeping view of the surrounding sea.
