Imperial Palace East Gardens

The Imperial Palace East Gardens occupy the former inner citadel of Edo Castle, the shogunal seat that once dominated the site now home to the Imperial Palace, and they have been open to the public as landscaped grounds since 1968. Visitors typically enter through the Ote-mon gate, following the original stone-walled approach used by feudal lords, and can climb the base of the former castle keep (tenshudai), whose massive stone foundation is all that survives of a five-story tower that burned down in 1657 and was never rebuilt. The grounds retain extensive sections of the castle's original cyclopean stone walls and moats, giving a strong sense of Edo-era defensive engineering even though the wooden structures themselves are long gone. The Ninomaru area holds a traditional Japanese strolling garden with a pond, and a smaller grove planted with trees and flowers donated by each of Japan's prefectures, making it a living map of regional flora. Plum trees bloom here in February, followed by cherry blossoms in late March and April, and maple foliage in November, giving the gardens three distinct seasonal peaks. A full visit, including the castle keep foundation, stone walls, and Ninomaru garden, takes about 90 minutes at an unhurried pace. Because the gardens are closed on Mondays, Fridays, and around the New Year holiday, visits need to be timed around the open schedule rather than fitted in casually. Crowds are generally light compared to other central Tokyo sites even during cherry blossom season, since many tourists overlook the gardens in favor of nearby Ueno or Shinjuku Gyoen; weekday mornings shortly after the 9:00 opening are the quietest. The stone tower ruins offer the best vantage point over the garden's layout and the surrounding modern skyline for photography.
