Title: Tokyo
Content:  Tokyo (Japanese: 東京, Tōkyō ), officially the Tokyo Metropolis (Japanese: 東京都, Tōkyō-to), is the capital and most populous prefecture of Japan. Located at the head of Tokyo Bay, the prefecture forms part of the Kantō region on the central Pacific coast of Japan's main island of Honshu. Tokyo is the political and economic center of the country, as well as the seat of the Emperor of Japan and the national government. As of 2021, the prefecture has an estimated population of 14.04 million. The Greater Tokyo Area is the most populous metropolitan area in the world, with an estimated 37.468 million residents in 2018. Originally a fishing village, named Edo, the city became

Title: Capital of Japan
Content:  While no laws have designated Tokyo as the Japanese capital, many laws have defined a "capital area" (首都圏) that incorporates Tokyo. Article 2 of the Capital Area Consolidation Law (首都圏整備法) of 1956 states: "In this Act, the term 'capital area' shall denote a broad region comprising both the territory of the Tokyo Metropolis as well as outlying regions designated by cabinet order." This implies that the government has designated Tokyo as the capital of Japan, although (again) it is not explicitly stated, and the definition of the "capital area" is purposely restricted to the terms of that specific law. Other laws referring to this "capital area" include the Capital Expressway Public Corporation Law (首都高速道路公団法) and the Capital Area Greenbelt Preservation Law (首都圏近郊緑地保全法). This term for capital was never used to refer to Kyoto. Indeed, shuto came into use during the 1860s as 
Title: Cities of Japan
Content:  Tokyo, Japan's capital, existed as a city until 1943, but is now legally classified as a special type of prefecture called a metropolis (都). The 23 special wards of Tokyo, which constitute the core of the Tokyo metropolitan area, each have an administrative status analogous to that of cities. Tokyo also has several other incorporated cities, towns and villages within its jurisdiction.

Following the end of the shogunate in 1868, the imperial capital in Kyoto was moved to the city, which was renamed Tokyo (literally "eastern capital"). Tokyo was devastated by the 1923 Great Kantō earthquake, and again by Allied bombing raids during World War II. Beginning in the 1950s, the city underwent rapid reconstruction and expansion, going on to lead Japan's post-war economic recovery. Since 1943, the Tokyo Metropolitan Government has administered the prefecture's 23 special wards (formerly Tokyo City), 
Title: Tokyo Metropolitan Government
Content:   The Tokyo Metropolitan Government (東京都庁) is the government of the Tokyo Metropolis. One of the 47 prefectures of Japan, the government consists of a popularly elected governor and assembly. The headquarters building is located in the ward of Shinjuku. The metropolitan government administers the special wards, cities, towns and villages that constitute part of the Tokyo Metropolis. With a population closing in on 14 million living within its boundaries, and many more commuting from neighbouring prefectures, the metropolitan government wields significant political power within Japan.

Content:   Tokyo, which is the center of the Greater Tokyo Area, is Japan's largest domestic and international hub for rail and ground transportation. However, its airspace has been under the US military's exclusive control after World War II. Public transportation within Tokyo is dominated by an extensive network of "clean and efficient" trains and subways run by a variety of operators, with buses, monorails and trams playing a secondary feeder role. There are up to 62 electric train lines and more than 900 train stations in Tokyo. Shibuya Crossing is the "world's busiest pedestrian crossing", with around 3,000 people crossing at a time.

Content:  Tokyo has the largest metropolitan economy in the world. According to a study conducted by PricewaterhouseCoopers, the Greater Tokyo Area (Tokyo–Yokohama, TYO) of 38 million people had a total GDP of $2 trillion in 2012 (at purchasing power parity), which topped that list. Tokyo is a major international finance center; it houses the headquarters of several of the world's largest investment banks and insurance companies, and serves as a hub for Japan's transportation, publishing, electronics and broadcasting industries. During the centralized growth of Japan's economy following World War II, many large firms moved their headquarters from cities such as Osaka (the historical commercial capital) to Tokyo, 
Title: Tokyo
Content:  In 1869, the 17-year-old Emperor Meiji moved to Edo, and in accordance, the city was renamed Tokyo (meaning Eastern Capital). The city was divided into Yamanote and Shitamachi. Tokyo was already the nation's political and cultural center, and the emperor's residence made it a de facto imperial capital as well, with the former Edo Castle becoming the Imperial Palace. The city of Tokyo was officially established on May 1, 1889. The Tokyo Metro Ginza Line portion between and  was the first subway line built in Japan and East Asia completed on December 30, 1927. Central Tokyo, like Osaka, has been designed since about 1900 to be centered on major railway stations in a high-density fashion, so suburban railways were built relatively cheaply at street level and with their own right-of-way. Though expressways have been built in Tokyo, the basic design has not changed. Tokyo went on to suffer two major catastrophes in the 20th century: the 1923 Great Kantō earthquake, which left 140,000 dead or missing; and World War II.
Title: Tokyo
Content:  Tokyo was originally known as, a kanji compound of 江 (e, "cove, inlet") and 戸 (to, "entrance, gate, door"). The name, which can be translated as "estuary", is a reference to the original settlement's location at the meeting of the Sumida River and Tokyo Bay. During the Meiji Restoration in 1868, the name of the city was changed to Tokyo (東京), when it became the new imperial capital, in line with the East Asian tradition of including the word capital (京) in the name of the capital city (for example, Kyoto (京都), Keijō (京城), Beijing (北京), Nanjing (南京), and Xijing (西京)). During the early Meiji period, the city was sometimes called "Tōkei", an alternative pronunciation for the same characters representing "Tokyo", making it a kanji homograph. Some surviving official English documents use the spelling "Tokei"; however, this pronunciation is now obsolete.
