Location
History
Umi-Shibaura Station opened on 1 November 1940 as a passenger stop on the privately operated Tsurumi Rinkō Railway, built on land owned by Toshiba's predecessor Shibaura Engineering Works. The Tsurumi Rinkō line was nationalised on 1 July 1943 and the station was later absorbed into Japanese National Railways, then JR East following the 1987 privatisation. Although unstaffed since 1 March 1971, the Toshiba security gate adjacent to the platform is staffed around the clock. The station was selected as one of the Kantō Top-100 stations in 2000 for its waterfront views of the Tsurumi-Tsubasa Bridge and the Yokohama Bay Bridge in the distance.
Notes
Because the station sits inside Toshiba's Keihin Works, the only way an ordinary visitor can exit is to board the next train back; Toshiba opens a small park, Umishiba Park, on the platform so passengers can pass the time during the wait.
