Under Mutsu Province
Shiwa District was one of the six districts of northern Mutsu Province (六奥郡) created in the early
Former Nine Years War (1051-1063), followed by the Kiyohara clan until the Gosannen War (1083-1089) and the Northern Fujiwara until 1189. During the Muromachi period, the area was claimed by the Nanbu clan
of northern Mutsu, but was ruled by the local Shiba clan until that clan was destroyed by the Nanbu in 1588.
Under the Tokugawa shogunate, Shiwa county consisted of 71 villages under the control of Morioka Domain and 4 villages under the control of Hachinohe Domain.
Early Meiji period
Following the
Meiji restoration, Shiwa District came under Rikuchū Province
and became part of Morioka Prefecture in 1871, with the exception of 4 villages which briefly became an exclave of Hachinohe Prefecture until absorbed into Morioka Prefecture as Shiwa Village a few months later. Morioka Prefecture became Iwate Prefecture in 1872.
