History
Sayamashi Station opened on 21 March 1895 as Irumagawa Station on the Kawagoe Railway, named for the then-municipality of Irumagawa-machi. It is one of the oldest stations on the entire Seibu Railway network, predating all others except Kokubunji, Ogawa and Higashi-Murayama. The east entrance was added in March 1975, and the station was renamed Sayamashi on 25 March 1979 when a new station building opened. From November 2008, a major redevelopment demolished the older station and its Seibu commercial building; the new station and east-west passageway came into use on 26 March 2010, and the Emio Sayamashi retail facility opened on 8 June 2011.
