Kokyo Gaien National Garden is a park in central Tokyo, covering a little over a square kilometer. The national garden includes three museums and is popular with people for its fascinating history and natural environment. The grounds ring the Imperial Palace, residence of the emperor, and include a landscaped plaza in front of the palace, 12 moats, and Kitanomaru Garden. These grounds were all once part of Edo Castle, originally built in 1457. Its moats as well as several gates, bridges, watchtowers, and impressive stone walls remain. Many are designated Special Historic Sites and Important Cultural Properties of Japan.

The castle was built during a time of conflict and political upheaval. It was constructed to protect Kamakura, the headquarters of the shogunate of the time, south of modern-day Tokyo. The Tokugawa shogunate, the feudal government that ruled the country from 1603 to 1867, expanded the castle making it the largest such stronghold ever built in Japan.

Over the centuries, Edo Castle was damaged by fire time and again. A fire in 1873 burned most of the castle to the ground. From 1874 to 1945, Kitanomaru Garden was occupied by the Imperial Guard.
