• Toei Mita Line: Hibiya ⇄ Onarimon

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 ticket gates on the first basement level and a shared utilities trunk on the second basement level in between. PASMO use began on 18 March 2007. Although officially a stand-alone station, the southern half of its platform reaches under Shimbashi and Nishi-Shimbashi in Minato ward, and it lies roughly 230 metres from Shimbashi Station, a relationship the operator does not recognise as a transfer.

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.
