Sangen-Jaya Station first opened on 6 March 1907 as a stop on the surface Tamagawa Electric Railway tramway in what is now Setagaya, Tokyo. The current Setagaya Line tram service over the connecting alignment began on 18 January 1925, the original Tamagawa Line was withdrawn on 10 May 1969, and an underground Shin-Tamagawa Line opened beneath the Route 246 corridor on 7 April 1977. Tram platforms were shifted to a temporary site on 11 November 1992 to allow redevelopment and moved into the new Carrot Tower terminus on 15 November 1996. The Shin-Tamagawa Line was absorbed into the Den-en-toshi Line on 6 August 2000, and platform-edge doors entered service on the subway level on 24 December 2017.

The Setagaya Line tracks here start at the 0.2-kilometre marker rather than zero: until the redevelopment that produced Carrot Tower, the bay platforms stood just short of the Sangenjaya crossing, and the rebuilt terminus was placed further toward Nishi-Taishidō, on the ground floor of Carrot Tower.
