History
Yachiyodai Station opened on 20 March 1956 as a Keisei Electric Railway stop on the Main Line in Yachiyo, Chiba. Before construction, the surrounding area was open grassland known as Narashinohara. Work on the east exit began in 1968 and finished in December 1969, when the platforms were extended to 160 metres and the building converted to an elevated structure. The station was nearly doubled in size in December 1993 with the addition of escalators and a wheelchair-accessible lift. Station numbering as KS29 was applied across Keisei on 17 July 2010. Four tracks today serve two island platforms; all passenger trains, including the Morning Liner and Evening Liner, call here.

Notes
A monument in the west exit plaza marks Yachiyodai as the "birthplace of the residential danchi housing estate" — the surrounding Yachiyodai estate, built by the Japan Housing Corporation in the mid-1950s, was the first government-scale planned suburban development of its kind.
