Facts about Tokyo
Tokyo is a vast metropolis, and it would take more than a lifetime to properly get to know it. Here is a collection of basic facts about Tokyo for a 5-minute overview of Japan's capital city.
Unless otherwise stated, all statistics are as of 2015.
Tokyo is the capital city of Japan, and the biggest city in Japan in terms of population and area. Tokyo is located roughly in the middle of the Japanese archipelago facing the Pacific Ocean. Tokyo is on the Kanto plain, bordering Tokyo Bay, 35 degrees 41 minutes north latitude and 139 degrees 46 minutes east longitude.
The Tokyo Megalopolis Region, or Greater Tokyo Area (Shutoen 首都圏), comprises Tokyo and the three adjacent prefectures of Chiba, Saitama, and Kanagawa. The Tokyo region contains about 26% of Japan's total population. Another definition of "Shutoen" is, in English, the National Capital Region and comprises Tokyo and seven surrounding prefectures: Chiba, Saitama, Kanagawa, Gunma, Tochigi, Yamanashi, and Ibaraki.
Two major rivers flow through Tokyo: the Sumida River, running north-to-south into Tokyo Bay, and the Tama River, running west-to-east, and forming the border between Tokyo and Kawasaki. The other major rivers are the Edo, Arakawa, and Kanda rivers.
Tokyo has a total land area of 2187.42 square km (about 845 square miles) and is home to about 10% of the population of Japan. Including the neighboring prefectures of Saitama, Chiba and Kanagawa, the Tokyo conurbation has a total population of over 37 million inhabitants, one of the largest population agglomerations in the world.

Tokyo history and politics
Tokyo is the seat of the Emperor of Japan, the figurehead of Japan's constitutional monarchy, who lives in the Imperial Palace (Kohkyo) in the heart of Tokyo.
Tokyo became a major city, and one of the world's most populous, from the beginning of the 17th century, when the city was called Edo, founded in the 12th century. In 1603, the warrior leader Tokugawa Ieyasu made it the seat of his feudal government. Tokyo became the capital of Japan (at the expense of Kyoto), and had its name changed from "Edo" to "Tokyo," in 1868 with the modernizing Meiji Restoration.
In 1964, Tokyo hosted the summer Olympic Games and will stage the Olympics again in 2020.
Tokyo's flower: Somei Yoshino (Yoshino cherry blossom, Prunus × yedoensis)
Tokyo's tree: Gingko (Ichoh in Japanese, Ginkgo biloba)
Tokyo's bird: Black-headed Gull (Chroicocephalus ridibundus)
Tokyo's official symbol, adopted in June 1989, comprises three green arcs forming the letter T in the shape of a ginkgo leaf. It is a symbol of Tokyo's growth, its prosperity, and tranquility.

Tokyo government and administration
Tokyo's status is on a par with the prefectures that make up Japan, but is known as a metropolis, or to (都), rather than a prefecture, or ken (県).
Tokyo consists of 62 municipalities: 23 wards, 26 cities, 5 towns, and 8 villages, the villages mostly consisting of the Izu Islands and the Ogasawara Islands off the coast of Tokyo, the furthest being 354 km away from the Tokyo Metropolitan government headquarters. The area of Tokyo to the west is known as the Tama Region.
The present governor of Tokyo, elected in 2016 is Yuriko Koike (b.1952), the first woman to hold the office. The Governor is elected by direct citizen vote, and represents the Metropolis of Tokyo for a renewable term of 4 years.
The former Governor of Tokyo was Yoichi Masuzoe (b.1948), a famous politician even before his election to Tokyo governor, a renowned political economist and expert on the problem of Japan's aging society. He was once a Diet member for the Liberal Democratic Party. Masuzoe resigned in June 2016 for misusing public funds.
Tokyo is administered by the Tokyo Metropolitan Government, which has its headquarters, known in Japanese as Tocho, in Shinjuku ward, west of Shinjuku Station. It is governed by the Tokyo Metropolitan Assembly (Tokyo-to gikai 東京都議会) made up of 127 members directly elected by Tokyo citizens to serve a term of four years.
As of April 1, 2015, the Tokyo Metropolitan Government employed a total of 167,914 persons.
In fiscal year 2015, the Tokyo Metropolitan Government's budget made up approximately 6.9% of the total budget of all the local bodies in Japan.
