Kyoto officially Kyoto City is the capital city of Kyoto Prefecture, located in the Kansai region of Japan. It is best known in Japanese history for being the former Imperial capital of Japan for more than one thousand years, as well as a major part of the Kyoto-Osaka-Kobe metropolitan area. During the 8th century, when powerful Buddhist clergy became involved in the affairs of the Imperial government, Emperor Kanmu chose to relocate the capital in order to distance it from the clerical establishment in Nara. His last choice for the site was the village of Uda, in the Kadono district of Yamashiro Province. Kyoto is located in a valley, part of the Yamashiro (or Kyoto) Basin, in the eastern part of the mountainous region known as the Tamba highlands. The Yamashiro Basin is surrounded on three sides by mountains known as Higashiyama, Kitayama and Nishiyama, with a height just above 1,000 metres (3,281 ft) above sea level. This interior positioning results in hot summers and cold winters. Kyoto has a humid subtropical climate.
