History
Motokaji Station began life as a freight stop — Kaji Freight Shed — opened on 12 November 1918 on the Musashino Railway, ancestor of today’s Seibu Ikebukuro Line. It was renamed Iwasawa Freight Shed in 1919 and converted to a full passenger station as Motokaji on 3 April 1926. A new station building opened in 1990. The stop was unmanned from January 1999 — the only unmanned station on the Seibu network at which Tokyo Metro trains called — until staff returned in August 2009. Seibu introduced station numbering across its lines in fiscal 2012, designating Motokaji as SI25, and through-running to Yokohama via Tokyu Toyoko commenced on 16 March 2013.
