  The area of present-day Ninohe was part of ancient Mutsu Province, and has been settled since at least the Jōmon period. Many Jōmon and Kofun period remains have been found. Inhabited by the Emishi tribes, the Nihon Shoki describes the penetration of the area by forces of the Yamato dynasty in the late Nara period; however, it was not under effective control of the central government until the mid-Heian period. The area was dominated by the Nanbu clan from the early Muromachi period, and was named for one of the nine numbered stockades, or fortified ranches, that established to secure this frontier area. During the Edo period, the area was under the control of Morioka Domain.

Jōbōji was elevated to town status on December 25, 1940. Gohenchi, Tomai, Ishikiridokoro, and Nisattai merged with Fukuoka on March 10, 1955. The modern city was founded on April 1, 1972, with the merger of the town of Fukuoka with the village of Kindaichi. On January 1, 2006, the city of Ninohe annexed the town of Jōbōji.
