Geography and Natural Environment
A Landscape Surrounded by Mountains and Rivers
Iiyama is surrounded on all sides by mountains, including Mount Madarao, Mount Nabekura, and Mount Kuroiwa. These mountains form part of the Sekita Mountain Range, which also extends along the border between Nagano and Niigata prefectures.
