The garden you see today is surprisingly young. After the Second World War, the area was renamed Imperial Residence in 1948, and the eastern part was renamed East Garden. It became a public park in 1968. Getting there took real work. Stables and housing were removed to create the garden in its present configuration. Construction began in 1961 with a new pond in the ninomaru, along with the repair and restoration of various keeps and structures from the Edo period. On May 30, 1963, the Japanese government declared the area a Special Historic Relic under the Cultural Properties Protection Law. Modern buildings sit comfortably among the old stones. The Tokagakudo, the Imperial Concert Hall, dates from 1966. In the sannomaru, the third circle, stands the Sannomaru Shozokan, the Museum of the Imperial Collections. Nearby you will also see the Imperial Household Agency building, and a bridge leading to the Sakashita-mon gate. Beyond the garden, the modern Kyuden, the palace for court functions and receptions, was completed in 1968 and put into use in April 1969. It stands in a separate zone, not part of the public garden.
