Tokyo, the capital of Japan, is one of the largest cities of the world with a population of 12.64-million and the biggest of the 47 prefectures throughout Japan. Its long history of prosperity started with the establishment of the shogunate by Tokugawa Ieyasu in 1603. At that time, Tokyo was called Edo, which by the 18th century had grown to a huge city of over a million people. It is now Japan’s center for political, economic, cultural, and various other activities as well as the origin for the dissemination of information.
Located geographically at about the center of the Japanese archipelago and in the southern part of the Kanto area, Tokyo shares borders with Chiba prefecture to the east along the Edogawa River, Yamanashi to the west along a mountain range, Kanagawa in the south along the Tamagawa River, and Saitama in the north. Being 2187 km2 in area, the metropolis occupies only 0.6% of the national land, the third smallest of the 47 administrative divisions of the country.
