query: What is the population of Tokyo?
passage: Tokyo
The 23 Special Wards of Tokyo were formerly Tokyo City. On July 1, 1943, it merged with Tokyo Prefecture and became Tokyo Metropolis with an additional 26 municipalities in the western part of the prefecture, and the Izu islands and Ogasawara islands south of Tokyo. The population of the special wards is over 9 million people, with the total population of Tokyo Metropolis exceeding 13.8 million.[3] The prefecture is part of the world's most populous metropolitan area called the Greater Tokyo Area with over 38 million people[4] and the world's largest urban agglomeration economy. As of 2011, Tokyo hosted 51 of the Fortune Global 500 companies, the highest number of any city in the world at that time.[12] Tokyo ranked third (twice) in the International Financial Centres Development Index. The city is home to various television networks such as Fuji TV, Tokyo MX, TV Tokyo, TV Asahi, Nippon Television, NHK and the Tokyo Broadcasting System.
passage: Tokyo
Architecture in Tokyo has largely been shaped by Tokyo's history. Twice in recent history has the metropolis been left in ruins: first in the 1923 Great Kantō earthquake and later after extensive firebombing in World War II.[72] Because of this, Tokyo's urban landscape consists mainly of modern and contemporary architecture, and older buildings are scarce.[72] Tokyo features many internationally famous forms of modern architecture including Tokyo International Forum, Asahi Beer Hall, Mode Gakuen Cocoon Tower, NTT Docomo Yoyogi Building and Rainbow Bridge. Tokyo also features two distinctive towers: Tokyo Tower, and the new Tokyo Skytree, which is the tallest tower in both Japan and the world, and the second tallest structure in the world after the Burj Khalifa in Dubai.[73]
