Location
History
Uchisaiwaichō Station opened on 27 November 1973 as a stop on the Toei Line 6, the route operated by Tokyo's Bureau of Transportation under the Toei subway brand. On 1 July 1978 that route was renamed the Mita Line, giving the station its present line identity. The station consists of a single underground island platform serving two tracks on the third basement level, with the concourse one level above and a utilities trunk in between. PASMO use began on 18 March 2007. Although officially a stand-alone station, its southern end sits beneath both Chiyoda and Minato wards and lies roughly 230 metres from Shimbashi Station, a relationship the operator does not recognise as a transfer.
Notes
The station's name comes from a riverside gate of the Edo-period outer moat called Saiwaibashi Gomon; the district's former name "Marunouchi-Saiwaichō" was shortened to "Uchisaiwaichō" in March 1872.
