Opened to the public in 1968, the Imperial Palace East Gardens (皇居東御苑, Kōkyo Higashi Gyoen) sit at the north-east corner of Tokyo Imperial Palace opposite the financial districts of Marunouchi and Otemachi. The grounds contains an Edo period style garden, the foundations of the former Edo Castle, and the Museum of Imperial Collections, which displays some of the Imperial Family household treasures.
