The area of Ōzu was part of ancientIyo Province. During theSengoku period, it was part of the holdings ofTōdō Takatora, who constructedŌzu Castle on top of a previous fortification dating to theKamakura period. In 1608, he was transferred and replaced by the Wakizaka clan, followed in 1617 by the Katō clan, who ruled the 66,000kokuŌzu Domain under theTokugawa shogunate. Ōzu developed in theEdo period as acastle town. The town of Ōzu was established withinKita District, Ehime with the establishment of the modern municipalities system on December 15, 1889. During theMeiji andTaishō 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.
Ōzu has amayor-council form of government with a directly elected mayor and aunicameral city council of 21 members. Ōzu, together with the town of Uchiko contributes two members to theEhime Prefectural Assembly.
In terms of national politics, Ōzu is part of Ehime 3rd district of thelower house of theDiet of Japan. Prior to 2022, the city was part of Ehime 4th district.[6]
Ōzu was once noted for its production of electronics; however, its factory by Matsushita Kotobuki Electronics closed in 2010 due to rapid deterioration in business performance. The economy is now centered on Agriculture (vegetables, livestock, citrus fruits) and forestry, with manufacturing of toothbrushes an important local product.
Ōzu has 20 public elementary schools and nine public middle schools operated by the city government, and four public high schools operated by the Ehime Prefectural Board of Education. The city also has one private middle school and two private high schools.
