Kyoto Prefecture is a prefecture of Japan located in the Kinki region of the island of Honshū. The capital is the city of Kyoto. For most of its history, the city of Kyoto was the Imperial capital of Japan. The history of the city itself can be traced back as far as the 6th century. In 544, the Aoi Matsuri was held in Kyoto to pray for good harvest and good weather. Kyoto did not start out as the capital of Japan. A noteworthy earlier capital was Nara. In 741, Emperor Shōmu moved the capital briefly to a place called Kuni-kyo, between the cities of Nara and Kyoto, in present-day Kyoto Prefecture. In 784, the capital was moved to Nagaokakyo, also in present-day Kyoto Prefecture. In 794, Emperor Kammu moved the capital to Heian-kyo, and this was the beginning of the current-day city of Kyoto. Even today, almost all of the streets, houses, stores, temples and shrines in the city of Kyoto exist where they were placed in this year. Although in 1192 real political power shifted to Kamakura, where a samurai clan established the shogunate, Kyoto still remained the imperial capital as the powerless emperors and their court continued to be seated in the city. Imperial rule was briefly restored in 1333, but another samurai clan established a new shogunate in Kyoto three years later. In 1467, a great civil war, the Ōnin no Ran, took place inside Kyoto, and most of the town was burned down. Japan plunged into the age of warring feudal lords. A new strong man, Tokugawa Ieyasu, established the shogunate at Edo (today's Tokyo) in 1603.
