The Imperial Palace East Garden, known also as Higashi Gyoen, is the main park of the palace grounds and is open to the public without prior reservations. It occupies the area of the former Honmaru and Ninomaru (first and second defense circles) of Edo Castle and have a total surface of 21 hectares. Aside from the moats and walls, nowadays only the foundations of the main tower remain of the castle.
The East Garden offers a wide variety of vegetation, including a collection of trees with at least one representative from each of Japan's prefectures, and is particularly popular among visitors during Spring for cherry blossom and plum blossom viewing. Visitors are given a token upon entering, which must be returned at the exit for control purposes. The garden is closed on Mondays and Fridays.
The Tokyo Imperial palace and gardens are located a few steps away from Otemachi Subway Station or in a 10 to 15 minute walk from Tokyo Station.
