About Tokyo
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 west of the city center. The Izu and Ogasawara Islands are also part of Tokyo. 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. A few decades later, Edo had grown into one of the world's most populous cities. Large parts of Tokyo were destroyed in the Great Kanto Earthquake of 1923 and in the air raids of 1945. Today, Tokyo offers a seemingly unlimited choice of shopping, entertainment, culture and dining to its visitors. The city's history can be appreciated in districts such as Asakusa and in many excellent museums, historic temples and gardens. Contrary to common perception, Tokyo also offers a number of attractive green spaces in the city center and within relatively short train rides at its outskirts.
Tokyo is the largest urban economy in the world by gross domestic product, and is categorized as an Alpha+ city by the Globalization and World Cities Research Network. Part of an industrial region that includes the cities of Yokohama, Kawasaki, and Chiba, Tokyo is Japan's leading center of business and finance. In 2019, it hosted 36 of the Fortune Global 500 companies. In 2020, it ranked fourth on the Global Financial Centres Index, behind New York City, London, and Shanghai. Tokyo has the world's tallest tower Tokyo Skytree and the world's largest underground floodwater diversion facility MAOUDC. Tokyo is an international center of research and development and is represented by several major universities, notably the University of Tokyo. Tokyo Station is the central hub for Japan's Shinkansen bullet train system, and the city is served by an extensive network of rail and subways. Notable districts of Tokyo include Chiyoda (the site of the Imperial Palace), Shinjuku (the city's administrative center), and Shibuya (a commercial, cultural and business hub).
Tokyo, as the center of the Greater Tokyo Area, is Japan's largest domestic and international hub for rail and ground transportation. However, its airspace has been under the US military's exclusive control after World War II. Public transportation within Tokyo is dominated by an extensive network of clean and efficient trains and subways run by a variety of operators, with buses, monorails and trams playing a secondary feeder role. There are up to 62 electric train lines and more than 900 train stations in Tokyo. Shibuya Crossing is the "world’s busiest pedestrian crossing", with circa 3,000 people crossing at a time. As a result of World War II, Japanese planes are generally forbidden to fly over Tokyo. Therefore, Japan constructed airports outside Tokyo. Narita International Airport in Chiba Prefecture is the major gateway for international travelers to Japan. Japan's flag carrier Japan Airlines, as well as All Nippon Airways, have a hub at this airport. Haneda Airport on the reclaimed land at Ōta, offers domestic and international flights.
