During the Kamakura period, the area was ruled by a branch of the Northern Fujiwara, followed by the Shiba clan during the Muromachi period. During the Sengoku period, the area was conquered by the Nambu clan in 1588. During the Edo period, Shiwa prospered as a post station on the Ōshū Kaidō highway connecting Edo with the northern provinces, as well as from its location on the Kitakami River. Initially part of Morioka Domain under the Tokugawa shogunate, from 1684, four villages formed an exclave of Hachinohe Domain.
