History
Tamachi Station opened on 16 December 1909 as an intermediate stop on the newly built Shinagawa–Karasumori segment of the Yamanote Line under the Railway Bureau, on a strip of waterfront that had earlier hosted a short-lived Tamachi temporary halt from December 1876 to September 1877. A Shibaura east entrance was added on 1 April 1926 to serve the reclaimed industrial district behind the station. Operation passed to JR East on 1 April 1987 at privatisation, automatic fare gates entered service in September 1991, and a widened east–west free passage opened on 8 February 2003. Major track realignment work to make room for the future Haneda Airport Access Line removed an adjacent siding in early 2024 and shifted the running tracks westward in April 2025.

Notes
In March 1868, Saigō Takamori and Katsu Kaishū met at a Satsuma warehouse on what is now the Mita side of Tamachi to negotiate the bloodless surrender of Edo Castle; a stele inscribed by Saigō's grandson marks the site.
