Geography
Tsunan is located in southwestern Niigata Prefecture, in a mountainous area bordering northern Nagano Prefecture. The town is located on a river terrace of the Shinano River with the town hall at an elevation of 241 meters; however, much of the town area is mountainous, with Mount Naeba (2143 meters) is partly located within the town limits. Due to its geographical location between the Sea of Japan and the surrounding Japanese Alps, it has one of the highest annual snowfalls in Japan. There are numerous ski resorts within the region.
