History

The area of Ōzu was part of the ancient Higo Province. During the Edo Period it was part of the holdings of the Kumamoto Domain. After the Meiji restoration, the town of Ōzu was established with the creation of the modern municipalities system on April 1, 1889.

Economy

Ōzu has an economy dominated by agriculture and manufacturing. Notably, there is a large Honda motorcycle factory located in Ōzu that employs people from around the world. There are many cattle farms in the area, and local farmers both raise cattle, and grow crops to provide feed for them. Ōzu is also known for its sweet potatoes (karaimo).

In 2024, after Taiwan Semiconductor Manufacturing Co. (TSMC) chose neighbouring Kikuyō as the location to build its second Japanese plant, Ōzu experienced the sharpest increase in commercial and industrial land prices of any area of Japan for the period ending July 1. This demand for land has caused problems for local farmers who rent farmland, since land owners have been asked to end their rental agreements early, giving up the land. In addition, local farmers are feeling a tension between possible short-term financial returns, and a wish to pass their farms on to their heirs as working farms.
