Levees are the most visible feature surrounding the city. To the west of the city is the border of Gifu and Mie prefectures, where the Yōrō Mountains run from north-to-south and the three major rivers of the Nōbi Plain (the Ibi, Nagara, and Kiso rivers) merge. The Tsuya, Ōgure, and Ōe rivers also flow through the city.
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.
Kaizu is home to Kisosansen Park. This is the location at which the Nagara, Ibi, and Kiso rivers meet. It is a great place to relax, enjoy outdoor sporting activities, or view the yearly flower festival held there. Because of the confluence of these three rivers and the area's geography, Kaizu was prone to flooding in ancient Japan. A panoramic view of the area can be viewed from an observation tower located in Kisosansen Park.
