The site was proclaimed a National National Historic Site in 1922. HistoryIn the late Nara period, after the establishment of a centralized government under the Ritsuryō system, the Yamato court sent a number of military expeditions to what is now the Tōhoku region of northern Japan to bring the local Emishi tribes under its control.[1] The Emishi were able to successfully resist the Japanese for several decades; however, in 802 AD, the Chinjufu-shōgun Sakanoue no Tamuramaro led an expedition with 4000 troops from the ten provinces of eastern Japan (Suruga, Kai, Sagami, Mushashi, Kazusa, Shimosa, Hitachi, Shinano, Kozuke and Shimotsuke) and built Isawa Castle as his stronghold within Emishi territory in the valley of the Kitakami River. With the defeat of the Emishi chieftain Aterui, many of the Emishi tribes in the Shiwa District submitted to Japanese rule. In 803 AD, Shiwa Castle was established in what is now part of the city of Morioka to serve as an administrative center of the imperial government. However, the site was prone to flooding, and in 811 AD, and Shiwa Castle was abandoned in favor of Tokutan Castle approximately ten kilometers to the south.[2] The garrison at Isawa Castle was reduced to 700 men in 815 AD, of whom many were local Emishi in the service of the Yamato court. By the middle of the 9th century, mention of Isawa Castle disappears from the historical record, although it may have existed in some form until the Gosannen War of 1083. See also
