Surrounded by a series of moats and high walls, the site of the former Edo Castle has been the official residence of the Japanese imperial family since 1868. It is considered as reputedly the most expensive square kilometer in the world, which during the height of Japan's bubble was estimated to be worth slightly more than California. Unfortunately, the inner palace gardens and buildings are closed to the general public except on January 2 and December 23, when the imperial family makes a public appearance.
