History
Shin-kōshinzuka Station (SA 20) is a Tokyo Toden Arakawa Line stop in Nishi-sugamo 3-chōme, Toshima, Tokyo. It was not present at the Ōji Electric Tramway's 1911 opening; instead it was opened in 1929 to serve the new Nakasendō (Route 17) construction in 1927–1931. The Tokyo City Tram Itabashi Line opened a Kōshinzuka stop on 19 April 1929, and the Ōji Electric Tramway added an Itabashi-shindō stop on 27 May. The two stops were merged and renamed Shin-kōshinzuka in March 1930. After Ōji Electric was absorbed by Tokyo City in 1942, the stop served both the Itabashi and Takinogawa (today Arakawa) lines until the Itabashi Line was abolished on 29 May 1966.

Notes
The Toei bus stop directly above the tram station has platform numbers 4 and 5 assigned to the Toden platforms themselves — the only case in Tokyo where bus platform numbers are mapped to a tram stop.
