Nara Prefecture is a prefecture in the Kinki region on Honshū island, Japan. The capital is the city of Nara. The present-day Nara Prefecture was created in 1887, making it independent of Osaka Prefecture. Historically, Nara Prefecture was also known as Yamato-no-kuni or Yamato Province. It is certain that a political force established at the foot of Mount Miwa in the east of Nara Basin, seeking unification of most parts in Japan from the third century until the fourth century, though the process was not well documented. At the dawn of history, Yamato was clearly the political center of Japan. Ancient capitals of Japan were built on the land of Nara, namely Asuka-kyō, Fujiwara-kyō (694–710) and Heijō-kyō (most of 710–784). The capital cities of Fujiwara and Heijō are believed to have been modeled after Chinese capitals at the time, incorporating grid layout patterns. The royal court also established relations with Sui and then Tang dynasty China and sent students to the Middle Kingdom to learn high civilization. By 7th century, Nara accepted the many immigrants including Korean refugees who had escaped from war disturbances of the southern part of the Korean Peninsula. The first high civilization with royal patronage of Buddhism flourished in today's Nara city (710–784 AD). In 784, Emperor Kanmu decided to relocate the capital to Nagaoka-kyō in Yamashiro Province, followed by another move in 794 to Heian-kyō, marking the start of the Heian period.
