History
Musashi-Sakai Station opened on 11 April 1889 as Sakai Station on what is now the Chūō Main Line in the city of Musashino, western Tokyo, and was renamed to its present name on 1 July 1919. The Seibu Tamagawa Line, which terminates at Musashi-Sakai, began operating on 22 October 1917. The current JR station building was completed in 2008 as part of the line's elevation works. Today the JR station is operated by East Japan Railway Company and served only by the slowest Chūō Rapid Line services, while the adjacent Seibu Tamagawa Line platform is operated by Seibu Railway as a single dead-headed island platform with two tracks.
