Before & After Photos of Famous Cities Over Time

Tokyo is Japan's capital and the world's most populous metropolis. It is also one of Japan's 47 prefectures, consisting of 23 central city wards and multiple cities, towns and villages. Prior to 1868, Tokyo was known as Edo. A small castle town in the 16th century, Edo became Japan's political center in 1603 when Tokugawa Ieyasu established his feudal government there. Today, it offers a seemingly unlimited choice of shopping, entertainment, culture and dining to its visitors.
