History
Keiō-tamagawa Station opened on 1 June 1916 as Tamagawara Station (多摩川原駅) of Keio Electric Tramway, in the city of Chōfu, Tokyo. At opening, the station was the terminus of a branch from Chofu Station, intended primarily for transporting gravel mined from the Tama River. Following the opening of Keio-en amusement park in 1927, the station also began carrying significant numbers of leisure passengers. The station was renamed Keiō-tamagawa Station on 1 May 1937 to distinguish it from the then-named Tamagawa-en-mae Station (later Tamagawa-en, now Tamagawa Station) of the Tokyo Yokohama Electric Railway. It became an elevated station on 21 December 1968 and an intermediate station on 1 April 1971 with the extension of the Sagamihara Line to Keio Yomiuri-Land Station. The station carries the station number KO35.

Notes
The station's 1937 rename to Keiō-tamagawa was driven by the need to distinguish it from another station — Tokyo Yokohama Electric Railway's Tamagawa-en-mae Station (later Tamagawa-en Station, now Tamagawa Station) on the present-day Tokyu Tōyoko Line. That station was renamed back to Tamagawa Station in 2000.
