Facts about Tokyo
Tokyo is a vast city, and it would take more than a lifetime to properly get to know it. Here is a collection of facts about Tokyo for an overview of Japan's capital city.
Unless otherwise stated, all statistics are as of 2012.
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, comprises Tokyo and the three adjacent prefectures of Chiba, Saitama, and Kanagawa. The Tokyo region contains about 26% of Japan's total population. The National Capital Region 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. Other rivers include the Edo, Arakawa, Sumida, Tama and Kanda rivers.
Tokyo has a total land area of 2187.42 square km 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 33 million inhabitants, the largest population concentration in the world.

Tokyo experiences numerous earthquakes. Before the March 11 2011 Tohoku earthquake, 2005 was the year when Tokyo had had the most earthquakes of over 1 on the Richter scale, with 85 earthquakes. The Tohoku earthquake was an upper 5 on the Japan Meteorological Agency (JMA) scale and the aftershocks over the next two months were innumerable. The yearly average for earthquakes over 1 on the Richter scale in Tokyo is about 50.
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 (then known as Edo, which had been founded in the 12th century) after 1603 when 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's status is on a par with the prefectures that make up Japan, but is known as a metropolis, or to, rather than a prefecture, or ken.
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 is 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. The Governor is elected by direct citizen vote, and represents the Metropolis of Tokyo for a renewable term of 4 years.
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 made up of 127 members directly elected by Tokyo citizens to serve a term of four years.
As of April 1, 2007, the Tokyo Metropolitan Government employed a total of 168,134 persons.
In fiscal year 2007, the Tokyo Metropolitan Government's budget represented 14% of the total budget of all the prefectural governments in Japan.
