Tokyo is both the capital and largest city of Japan. As a "metropolitan prefecture", Tokyo combines elements of both a city and prefecture and is governed by the Tokyo metropolitan government which oversees 23 special wards and 39 other municipalities. The total population of Tokyo exceeds 13 million, making it the most populous metropolitan area in the world. Tokyo has a long history, originally being a small fishing village before becoming the seat of the Tokugawa shogunate in the 17th century and the imperial capital after 1868. Today, Tokyo is a global financial center and known for its pop culture, museums, festivals, and cuisine.
