The area around Kaizu was part of traditional Mino Province. A midden from Jōmon period was found in Kaizu, which includes sea shells, tools, and human remains. These artifacts indicate that the area was settled as early as 2,500 years ago. Around these period, Kaizu was much closer to the ocean and many basket clam shells can be found. In 1319, towards the end of the Kamakura period, the first circle levee was completed. Originally, levees were only on the upstream portion of the city, leaving the downstream side vulnerable to floods. Once the full circle levee was completed, numerous other circle levees were built in the surrounding area. During the Edo period, most of the area was divided between Takasu Domain and tenryō territory under direct control of the Tokugawa shogunate. Many of the events of the 1754 Horeki River incident occurred in this area. During the post-Meiji restoration cadastral reforms, the area was organised into Ishizu District, Gifu. The town of Takasu of created on July 1, 1889 with the establishment of the modern municipalities system. During the early Meiji period, the foreign advisor Johannis de Rijke worked on improving flood control and man of the dikes in this area. The town of Kaizu was established on January 15, 1954 by the merger of Takasu with four neighbouring villages. The modern city of Kaizu was established on March 28, 2005, from the merger of the former town of Kaizu, absorbing the towns of Hirata and Nannō (all from Kaizu District).[5]


Kaizu has a mayor-council form of government with a directly elected mayor and a unicameral city legislature of 15 members.
