Kiso Three Rivers

At various points downstream, the rivers flow together and then separate again, often leading to flooding and water damage.

Since the Edo period, much work has been done to plan dykes and other structures that will help control the rivers.

In the late part of the 19th century, rulers of the Satsuma domain worked with the Dutch engineer Johannis de Rijke to help with flood control of the area.

From the park, visitors can see each of the three rivers, as well as Ise Bay and the mountains surrounding the Nōbi Plain.
