Mount Iide is located at 2105 m[2] above sea level but is not the highest peak of the Iide mountain range even though it is the main peak of the range. The highest is Mount Dainichi (大日岳, Dainichi-dake) that is 2128 m high.[2]
The mountain is located on the border between Niigata prefecture and Yamagata prefecture, but the summit itself, Mount Iide Shrine and a path roughly one meter wide leading there belongs to Kitakata, Fukushima. This was a response to complaints when Higashikanbara District was transferred from Fukushima to Niigata during the Meiji period. As a result, Fukushima prefecture has an uneven border, with an arm stretching through the Iide mountain range up to the Mount Iide Shrine.[3]
