The area of present-day Taiwa was part of ancient Mutsu Province, and has been settled since at least the Jōmon period by the Emishi people. Numerous kofun were built in the area during the Kofun period. During later portion of the Heian period, the area was ruled by the Northern Fujiwara. During the Sengoku period, the area was contested by various samurai clans before the area came under the control of the Date clan of Sendai Domain during the Edo period, under the Tokugawa shogunate. Yoshioka-juku developed as a major post station on the Ōshū Kaidō during this time. Following the Meiji restoration, the town of Yoshioka was established with the creation of the modern municipalities system.

The town of Taiwa was created on April 20, 1955, as a result of a merger between the town of Yoshioka, and the villages of Miyatoko, Yoshida, Tsurusu, and Ochiai, all within Kurokawa District.
