In 1867, after the Meiji Restoration, the gardens were used as a villa by the Iwasaki family, owners of the Mitsubishi Group. It was also used as a temporary residence of the prime minister before being donated to the city and opening as a public park in 1937.
It is not a very large park, but it is a beautiful one. Walking paths surround a pond with an inlet. It was a nice, quiet retreat, especially if you first explore the traditional shopping area of Sugamo.
