History
Kaijin Station opened on 25 October 1919 as a station on Keisei Electric Tramway (the predecessor of Keisei Electric Railway) in the city of Funabashi, Chiba Prefecture. From 25 December 1929 the Sōbu Railway Kaijin Line connected here, but operations on the connecting line were suspended in November 1933 and the line was abolished on 3 April 1934, leaving Kaijin again as a Keisei Main Line station. On 1 March 1981 a new station building was completed on the down-line side together with a footbridge; the earlier level crossing and up-line side station building were retired the same day. The station was renovated in fiscal 2012, and the footbridge was renewed on 31 March 2023. Station numbering was introduced across the Keisei Line on 17 July 2010, and Kaijin was assigned the number KS21.
