Map of Urban Renaissance (UR) Toyoshiki-dai Danchi ＵＲ都市機構豊四季台団地. Located in Kashiwa-City, Chiba Prefecture (map).
According to Wikipedia, the danchi was built in 1964 and had a capacity of 10,000 people. It is located on the site of the former Kashiwa Horsetrack 柏競馬場, which closed in the 1950s (at was partially hurt by the post-war rise of keirin bicycle racing). Starting in the 2000’s, sections of the danchi have undergone redevelopment.
