• Tōkaidō Main Line: Shimbashi ⇄ Tamachi

Hamamatsuchō Station opened on 16 December 1909 as an intermediate station on the Railway Board's newly opened Shinagawa - Karasumori (later Shimbashi) section of the Tokyo elevated line. At opening it served only the Yamanote-line electric services on a single 93.6 m island platform. With the opening of Tokyo Station on 20 December 1914 the station came under the formal Tōkaidō Main Line and Keihin Line (later Keihin-Tōhoku Line) electric trains began stopping. The Yamanote and Keihin-Tohoku Line tracks were separated on 19 November 1956, giving the JR portion of the station its present two-island four-track configuration. Tokyo Monorail's terminal station opened on 17 September 1964, and the Toei Asakusa Line's Daimon Station opened on 1 October 1964 as a within-walking-distance transfer point. With privatization of Japanese National Railways on 1 April 1987 the JR portion came under JR East, and Tokyo Monorail was acquired by JR East in 2002.

On the Yamanote and Keihin-Tōhoku southbound (track 3/4) platform stands a small "Pee Boy" (Manneken Pis) statue, gifted as a white porcelain figurine to the stationmaster on 14 October 1952 to mark the 80th anniversary of Japanese railways. The original was replaced with a bronze cast on the platform's renewal in May 1955, and from November 1986 a volunteer team has continued to dress the statue in a new monthly costume — a tradition that has now run for forty years.
