Tokyo Imperial Palace (皇居, kōkyo; literally Imperial Residence^?) is the main residence of the Emperor of Japan. It is a large park-like area located in Chiyoda, Tokyo close to Tokyo Station and contains various buildings such as the main palace (Kyūden (宮殿^?)) and the private residences of the imperial family. The total area including the gardens is 7.41 square kilometers. During the height of the 1980s Japanese property bubble, the palace grounds were valued by some as more than the value of all the real estate in the state of California.
