Nōbi Plain

It is bordered on the west by the Ibuki and Yōrō mountain ranges, and to the east by the Owari Hills.

Its northern border is marked by the Ryōhaku Mountains and the south by Ise Bay.

Because the water levels can change rapidly due to storms, there was often much water damage throughout history, leading to many distinct cultural habits, such as municipalities surrounded by earthen rings (e.g. Wanouchi, Gifu Prefecture).

The modern cities of Tsushima and Nagoya in Aichi Prefecture were built on low-level plateaus to ward off water damage and flourished as a result.

Sedimentation from the three rivers forms the eastern edge of the plain, which easily shows the declination of the area.
