Mount Iizuna forms the Iizuna range. It has an elevation of 1,917 metres.
This mountain is a sacred site for mountain-based religious sects such as Shugendo, and said to be the home of a tengu named Saburō. According to legend, there was once a strange, edible sand somewhere on the mountain, which the tengu would distribute in times of poor harvest.
The mountain is also a popular area for skiing. It was where the bobsleigh and luge track for the 1998 Winter Olympics was located.
