Tsudayama Station opened on 5 February 1941 as Nihon Hume Tube Mae Stop on the Nambu Railway, serving the nearby Nihon Hume pipe plant that had relocated from Yokohama the previous year. The stop was raised to full station status on 9 April 1943. Nationalisation on 1 April 1944 brought it under the Ministry of Transport and Communications' Nambu Line and simultaneously renamed it Tsudayama, then under Japanese National Railways from 1949. Freight ceased on 5 March 1972 and JR East took over on 1 April 1987. A long-pending elevated concourse opened in stages: the north entrance on 8 June 2019, the south entrance and free passageway on 22 May 2020. Smart platform doors began service on 8 August 2024.

The "Tsudayama" name comes from another name for Mount Shichimen east of the station — a rebranding coined by Tsuda Kōji, president of the Tamagawa Electric Railway, who developed the surrounding land for housing.
