History
Musashi-Koyama Station opened on 11 March 1923 as Koyama Station on the Meguro-Kamata Railway in Shinagawa, Tokyo, with one island platform and a freight platform. It was renamed Musashi-Koyama on 20 April 1924 to disambiguate from Oyama Station on the Tohoku Main Line, with the "Musashi" prefix from the old province name. A reinforced-concrete station building replaced the original in November 1925, and freight tracks were removed in February 1937. The Meguro-Senzoku continuous grade-separation project saw the station moved to a temporary elevated structure in July 1997 and underground in two-island-four-track form on 2 July 2006. A station building above ground opened on 17 September 2010.

Notes
The "Musashi" prefix was added because a Koyama Station already existed on the JNR Tōhoku Main Line, although that station is read "Oyama" rather than "Koyama".
