Sukayu Onsen, despite the incredibly high yearly snowfall, has a humid continental climate (Dfb), and is one of the coldest and snowiest inhabited places in Japan. Summers are generally short, but mild to warm with many rainy days. Winters are cold by Japanese standards and extremely snowy, due to the high elevation. Springs and Autumns can be highly variable, being rainy, snowy, cold, mild, sunny, or all kinds of weather in a week.
