History
Toritsu-Kasei Station opened on 25 December 1937 on what is now the Seibu Shinjuku Line, originally as Furitsu-Kasei Station in Nakano Ward, Tokyo. The stop was built at the request of the parent-teacher association of the nearby Tokyo Prefectural Nakano Domestic-Sciences Girls' High School (now Tokyo Metropolitan Saginomiya High School) and was renamed Toritsu-Kasei on 1 July 1943 when the Tokyo prefecture-cum-municipality (Tōkyō-fu) was abolished. A new station building was inaugurated on 28 July 1983, and a yard improvement in spring 1984 replaced the in-station level crossing with a connecting underground passage. Automatic ticket gates entered service at the south entrance on 21 February 1992. The station was numbered SS08 in fiscal 2012.

Notes
Toritsu-Kasei sits just 500 m from Saginomiya, the shortest interstation spacing on the entire Seibu Shinjuku Line — the platforms are only 300 m apart and passengers can see one station from the other.
