History
The area of Ōzu was part of ancient Iyo Province. During the Sengoku period, it was part of the holdings of Tōdō Takatora, who constructed Ōzu Castle on top of a previous fortification dating to the Kamakura period. In 1608, he was transferred and replaced by the Wakizaka clan, followed in 1617 by the Katō clan, who ruled the 66,000 koku Ōzu Domain under the Tokugawa shogunate. Ōzu developed in the Edo period as a castle town. The town of Ōzu was established within Kita District, Ehime with the establishment of the modern municipalities system on December 15, 1889. During the Meiji and Taishō periods (late 19th century, early 20th century), Ōzu saw great economic expansion due to thriving silk and Japanese wax candle (和蠟燭, warōsoku) industries. A robust timber trade also occurred during this time, with Hiji River serving as a transportation artery. However, transformations brought by the arrival of railways and motorways disrupted the balance of the local economic cycle.

On September 1, 1954, town of Ōzu merged with the villages of Hirano (平野村), Awazu (粟津村), Miyoshi (三善村), Kamisukai (上須戒村), Minamikume (南久米村), Sugeta (菅田村), Niiya (新谷村), Yanagisawa (柳沢村) and Ōkawa (大川村) to form the city of Ōzu. On January 11, 2005 Ōzu annexed neighboring Nagahama, Hijikawa, and Kawabe municipalities.
