# Umi-Shibaura Station

Umi-Shibaura Station (海芝浦駅, Umi-shibaura-eki) is a railway station on the Tsurumi Line in Tsurumi-ku, Yokohama, Kanagawa Prefecture, Japan, operated by East Japan Railway Company (JR East). The station is located on the grounds of Toshiba's Keihin Product Operations, and the only exit from the station is into the company's grounds. As a result, only Toshiba employees with valid employee ID cards and invited visitors are permitted to exit the station. A small park next to the station is open for public use; however there is no pedestrian exit from the station or park and anyone other than authorised Toshiba employees or visitors must exit by using a train.

## History

Umi-Shibaura Station was opened on 1 November 1940 as a station on a spur line of the privately held Tsurumi Rinkō Railway (鶴見臨港鉄道, Tsurumi Rinkō Tetsudō). 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 Tokyo Bay.
