Tokyo Metropolis is Japan’s de facto capital, located in the Kanto region, and one of the country’s designated “to” (metropolitan prefectures). Its metropolitan government headquarters are located in Nishi-Shinjuku, Shinjuku Ward, officially defined by the Tokyo Metropolitan Ordinance.
Tokyo’s administrative divisions are composed of three main areas: the Special Wards Area (commonly known as the “23 Wards of Tokyo”), the Tama Area (26 cities and 3 towns and 1 village in Nishitama District), and the Islands Area (2 towns and 7 villages). Geographically, most of Tokyo lies in the southwestern part of the Kanto Plain, stretching in a long east–west orientation. The eastern part faces Tokyo Bay, while the western part includes the Kanto Mountains, with Mount Kumotori (2,017 m) as the highest peak. Tokyo also governs the Izu Islands and the Ogasawara Islands in the Pacific, which include Okinotorishima, Japan’s southernmost point, and Minamitorishima, its easternmost point. Thus, Tokyo encompasses the country’s southernmost and easternmost territories.
As Japan’s political, economic, cultural, and academic hub, Tokyo hosts the headquarters of the legislative, executive, and judicial branches of government, as well as the majority of foreign embassies and consulates. Major domestic and international financial institutions, multinational corporations, media outlets, and numerous universities and research institutes are concentrated here. In terms of transport, Tokyo serves as the nation’s core hub for rail, road, and air networks.
Tokyo’s jurisdiction stretches across about 1,700 km north to south and 1,900 km east to west, due to its inclusion of Okinotorishima and Minamitorishima, making it the Japanese prefecture with the greatest geographical span. Its land area is 2,199.94 km², ranking 3rd smallest among Japan’s 47 prefectures (larger only than Kagawa and Osaka). The population center of Tokyo is located in Matsunoki 1-chome, Suginami Ward.
The climate is classified mainly as humid subtropical (Cfa) under the Köppen system, but varies widely due to geography. The 23 wards feature warm, humid summers and mild winters, while western Tama has more inland/continental influences, and the Ogasawara Islands exhibit a southern oceanic climate. Tokyo has four distinct seasons, with rainy spells in June–July (tsuyu), hot and humid summers with frequent thunderstorms, typhoon-affected autumns, and dry, sunny winters.
Tokyo’s urban heat island effect is notable. According to the Japan Meteorological Agency, the number of winter days below 0°C has dropped sharply compared to the Taisho and early Showa eras, while tropical nights (minimum temperature above 25°C) have tripled. In some years, central Tokyo’s winter lows have even been warmer than southern cities like Kagoshima or Miyazaki.
