History
Nishi-Koyama Station opened on 1 August 1928 on the Tokyu Meguro Line in Shinagawa, Tokyo. From 4 October 1995 work began on the continuous grade separation of the Meguro–Senzoku stretch, and on 5 June 1999 a temporary elevated structure took over while reconstruction continued. On 6 August 2000 the Mekama Line was split into the Meguro Line and the Tokyu Tamagawa Line, transferring the station to the new Meguro Line. Platform doors entered service on 29 July 2001, and the station was relocated underground on 2 July 2006. A three-storey station building over the new tracks opened on 10 April 2008.
