The present Imperial Palace encompasses the retrenchments of the former Edo Castle.
The modern  Kyūden (宮殿) designed for various imperial court functions and receptions is located in the old Nishinomaru section of the palace grounds.
 On a much more modest scale, the Fukiage Palace (吹上御所, Fukiage gosho), the official residence of the Emperor and empress, is located in the Fukiage Garden.
Designed by Japanese architect Shōzō Uchii the modern residence was completed in 1993.
This residence is currently (July 2020) not in use and being prepared for Naruhito, who for the time being keeps his primary residence at the former Tōgū Palace, renamed Akasaka Palace (赤坂御所, Akasaka gosho) while he resides there.

Except for the Imperial Household Agency and the East Gardens, the main grounds of the palace are generally closed to the public, except for reserved guided tours from Tuesdays to Saturdays (which access only the Kyūden Totei Plaza in front of the Chowaden).
Each New Year (January 2) and Emperor's Birthday, the public is permitted to enter through the Nakamon (inner gate) where they gather in the Kyūden Totei Plaza.
The Imperial Family appears on the balcony before the crowd and the Emperor normally gives a short speech greeting and thanking the visitors and wishing them good health and blessings.
Parts of the Fukiage garden are sometimes open to the general public.

The old Honmaru, Ninomaru, and Sannomaru compounds now comprise the East Gardens, an area with public access containing administrative and other public buildings.

The Kitanomaru Park is located to the north and is the former northern enceinte of Edo Castle.
It is a public park and is the site of the Nippon Budokan.
To the south is Kokyo Gaien National Garden.
