The site was once the Edo residence of the Echigo Takada clan and later became the main residence of the Iwasaki family. At its largest, the property covered about 49,500 m² and had more than 20 buildings. Three remain today: the Western-style residence, the billiard building and part of the Japanese-style residence. After World War II the property belonged to the national government, and it opened to the public as a Tokyo metropolitan garden in October 2001.
