Kojiya Station serves the Keikyu Airport Line in Nishi-Kojiya, Ota, Tokyo, under station number KK12. It opened on 28 June 1902 when the Keihin Electric Railway opened the Anamori Line (today's Airport Line) between Kamata (now Keikyu Kamata) and the original Anamori Station. Modernisation between October 1991 and March 1993 produced a new station building and longer, wider platforms; the platforms were extended again in December 1994 to handle eight-car trains running through to the Toei Asakusa Line. Through services to and from central Tokyo began when Haneda Station (now Tenkubashi) opened on 1 April 1993. The up tracks were elevated on 16 May 2010, and the down tracks followed on 21 October 2012.

The station name preserves the old place name Kōjiya — written 糀谷 and still found in the names of nearby shops, schools, and the local shōtengai — even though no town today carries that name on its own.
