History
Midoridai Station opened on 22 February 1922 as Hama-Kaigan Station on the Keisei Chiba Line in what is now Inage Ward, Chiba. On 1 April 1942 it was renamed Teidai Kogakubu-mae after the nearby engineering campus of Tokyo Imperial University, then shortened to Kogakubu-mae once the university dropped "Imperial" after World War II. A further rename took effect on 1 May 1951, when the station became Kurosuna, and it took its present name Midoridai on 1 October 1971. Operated by Keisei Electric Railway, the station has two opposing side platforms connected by an overpass, and lies 9.9 kilometres from the line's terminus at Keisei-Tsudanuma. Station numbering across the Keisei network was introduced on 17 July 2010, assigning Midoridai the code KS56.
