Yamato Province (大和国 Yamato no Kuni?) was a province of Japan, located in Kinai, corresponding to present-day Nara Prefecture in Honshū. It was also called Washū (和州?). At first, the name was written with one different character (大; cf. Names of Japan), and for about ten years after 737, this was revised to use more desirable characters (大). The final revision was made in the second year of the Tenpyō-hōji era (c. 758). It is classified as a great province in the Engishiki.
The Yamato Period in the history of Japan refers to the late Kofun Period (c. 250–538) and Asuka Period (538–710). Japanese archaeologists and historians emphasize the fact that during the early Kofun Period the Yamato chieftainship was in close contention with other regional powers, such as Kibi Province near present-day Okayama Prefecture. Around the 6th century, the local chieftainship gained national control and established the Imperial court in Yamato Province.
