Tokyo, in a narrow sense, refers to Tokyo in the corner of kanto region, located at the southern end of the Kanto Plain, facing Tokyo Bay, and roughly located in the center of the Japanese archipelago, with a total area of 2 155 square kilometers.
Tokyo borders Edogawa in the east, Yamanashi in the west, Kanagawa in the south and Saitama in the north.
In addition to Japan, the formal administrative divisions have to be supplemented by outlying islands such as Ogasawara Islands and Izu Islands. Japan's southernmost (Okinawa Island) and easternmost (Nanniao Island) are also under the jurisdiction of Tokyo.
The 23 special zones in Tokyo and Tama form a narrow strip, 90 kilometers wide from east to west and 25 kilometers long from north to south. Izu Islands and Ogasawara Islands in the Pacific Ocean are geographically separated from Tokyo. It is also part of the administrative division of Tokyo.
