History[edit]
The Ibara area is part of ancient Bitchū Province and was the site of a shōen landed estate ruled by the Nasu clan. In the Muromachi period, the lord of Ibara-shō, Ise Moritoki, went to Suruga Province in 1476 to assist his nephew Imagawa Ujichika succeed to the head of the Imagawa clan. Ise Moritoki later changed his name to Hōjō Sōun and seized control of the Kanto region from his stronghold at Odawara Castle. During the Edo Period, it was largely divided between the holdings of Fukuyama Domain and direct territory of the shogunate. Following the Meiji restoration, the area was organized into villages within Shitsuki District, Okayama with the creation of the modern municipalities system on April 1, 1889. Ibara was elevated to town status on February 26, 1896.
