• Tokyu Toyoko Line: Higashi-hakuraku ⇄ Yokohama

Tammachi Station opened on 14 February 1926 on what is now the Tōkyū Tōyoko Line. The original two-platform surface station, partly elevated at its Higashi-Hakuraku end, was relocated underground on 31 January 2004 in preparation for through-running with the Yokohama Minatomirai Line, which began the following day. A new station building was put into service on 28 March 2006, with new ticket-gate and ticket-machine layouts. Platform-edge doors entered service in 2017.

Tammachi is the least-used station on the entire Tōkyū Tōyoko Line. The old girder bridge that once carried the Tōyoko Line over National Route 1 north of the station survives as a pedestrian bridge: in 2009 the City of Yokohama reinforced the original piers and girders and laid a pedestrian deck on top of them, creating the Tōyoko Flower Promenade Tanmachi Bridge.
