Kyoto is a city located in the central part of the island of Honshu, Japan. It has a population close to 1.5 million. Formerly the Imperial capital of Japan for more than one thousand years, it is now the capital city of Kyoto Prefecture located in the Kansai region, as well as a major part of the Kyoto-Osaka-Kobe metropolitan area. Kyoto is also known as the thousand-year capital. Osaka (大阪市) is a designated city in the Kansai region of Japan. It is the capital city of Osaka Prefecture and the largest component of the Keihanshin Metropolitan Area, the second largest metropolitan area in Japan and among the largest in the world with over 19 million inhabitants. Situated at the mouth of the Yodo River on Osaka Bay, Osaka is the second largest city in Japan by daytime population after Tokyo's 23 wards and the third largest city by nighttime population after Tokyo's 23 wards and Yokohama, serving as a major economic hub for the country. Tokyo (東京), officially Tokyo Metropolis (東京都 Tōkyō-to),[4] is one of the 47 prefectures of Japan,[5] and is both the capital and most populous city of Japan. The Greater Tokyo Area is the most populous metropolitan area in the world.[6] It is the seat of the Emperor of Japan and the Japanese government. Tokyo is in the Kantō region on the southeastern side of the main island Honshu and includes the Izu Islands and Ogasawara Islands.[7] Formerly known as Edo, it has been the de facto seat of government since 1603 when Shogun Tokugawa Ieyasu made the city his headquarters. It officially became the capital after Emperor Meiji moved his seat to the city from the old capital of Kyoto in 1868; at that time Edo was renamed Tokyo. Tokyo Metropolis was formed in 1943 from the merger of the former Tokyo Prefecture (東京府 Tōkyō-fu) and the city of Tokyo (東京市 Tōkyō-shi).
