History
Shimura-sakaue Station opened on 27 December 1968 with the inauguration of Toei Subway Line 6 — having been carried through planning under the working name "Shimura-itchōme" — and the line was redesignated as the Mita Line on 1 July 1978. The station sits underground with two side platforms, but the tunnel mouth is at the western end of the platforms and the line surfaces immediately afterwards, running on viaduct as far as the Nishi-Takashimadaira terminus. Day-to-day station operations were transferred to a contracting body on 21 March 2003, PASMO IC cards have been accepted since 18 March 2007, and a 2013 refurbishment replaced the long-serving illuminated platform-wall signage with the newer style now familiar from Mita Station.
