History
Musashi-Sunagawa Station opened on 12 December 1983 as a petition station on the Seibu Haijima Line, the newest stop on that line. Local lore traces its origin to a 1960 promise to landowners during right-of-way acquisition. In May 1976 Tachikawa and Musashimurayama set up a joint promotion council with their councils, agreement on a new petition station was reached in 1979, and a 1980 deal split the bill — Seibu funded the track, while the two cities funded the building and platforms, with Musashimurayama paying 100 million yen (50 million of it borne by Nissan) and Tachikawa covering the balance. Construction began in July 1982. An LED departure-information board was installed in September 2006, lifts entered service after a toilet and accessibility refurbishment in February 2014, and on 25 March 2025 the ticket window closed in favour of remote intercom support.
