Tokyo, Tokyo-, or Tokyo (Tokyo (とうきょう), English: Tokyo), located in eastern Honshu, Japan, is the de facto capital and largest city of Japan since the Meiji period. Although it belongs to the Tokyo Metropolitan Government in terms of administrative division, Tokyo has a slightly different meaning from "Tokyo," meaning a city, because it includes a large area of the Tama region, the Izu Islands, and the Ogasawara Islands.
In Tokyo, there are various Japanese government ministries and Imperial Palaces where the emperor resides. Tokyo is the most developed city in the world for manufacturing. In addition, many multinational corporations have their headquarters or branch offices in Tokyo, and are the center of the world's game industry, manga and animation industry, video, digital, and high-tech industries. Tokyo has the world's largest subway transportation network and constitutes the world's largest metropolitan area. It is called the world's three largest economic capitals along with New York and London.
The name Tokyo was named in accordance with the decree issued in September 1868 (the first year of Meiji or July of the 4th year of Keio), "To name Edo and to call it Tokyo", It is derived from the establishment of the Tokyo Prefectural Government (東京府), which had jurisdiction over the area under the jurisdiction of the 町奉行. The Chinese character "Tokyo" means "the capital of the east" in Kyoto. Until the middle of the Meiji period, the notation '東亰' was also used. (亰 is shorthand for kyo)
It was in the middle of the Meiji period that this area was pronounced "Tokyo", and it was previously called "Tokei" (Tokyo, written in Chinese characters). In Keihin Industrial Zone, Keihin Express Railway, and Keio Railway, which are often referred to as a combination of Tokyo and Yokohama, "Kei" is derived from "Tokei", another name used to read Tokyo in the past.
After the Meiji Restoration, the leaders of the new government considered relocating to Edo, but it is said that they declared "Edo is also a capital city" for the reason that there was a strong opposition from Kyoto aristocrats and officials at the time. And the emperor's move was planned under the pretext that "Even since Edo has become a (Japan's) capital city, the emperor needs to conduct administration in Edo (Tokyo) as well." Emperor Meiji entered Tokei Castle (former Edo Castle) in November 1868 (October of the first year of Meiji), and returned to Kyoto once thereafter. In May 1869 (March 2nd Meiji), it was moved again to Tokyo (at this time Tokei Castle became "Imperial Castle"), and the coffin was also moved.
After that, the Japanese emperor and government no longer returned to Kyoto, and it is said that the de facto capital of Tokyo was achieved. Until now, the 'Tokyo Capital' itself has not been specified by Japanese laws, and there is no decree that directly designated Tokyo as the capital in Japan. As the capital of the empire (Empire of Japan)" However, the Kyoto Eoso remains unresolved until now, and in the shrine's Shishinden (紫宸殿), there is an enshrined seat indicating the emperor's residence. Accordingly, there are also opinions that deny the capital.
There is also an opinion that it is reasonable to regard Tokyo, the seat of the National Assembly, the highest organ of national sovereignty, as the capital because Japan declared that sovereignty rested with the people, not the emperor, according to the Japanese constitution after World War II. On the other hand, in Japan, in recent years, there are plans to move the water supply function from Tokyo to the Tochigi and Fukushima regions (Nasu), Gifu and Aichi regions (Tono), and the Miegio region (�
