The area of present-day Shizukuishi has been inhabited since the earliest times. Archaeologists have found remains dating to the Japanese Paleolithic period. The area come under the control of the Yamato dynasty during the early Heian period under the campaigns of Sakanoue no Tamuramaro, and was part of ancient Mutsu Province. The area was a battlefield during the Former Nine Years War and the Gosannen War. It eventually came under the control of the Nambu clan, who ruled from Morioka Domain under the Edo period Tokugawa shogunate.
