Nanao Korosa, or just Korosa, is a ski area located in Nanao City in the northern region of Ishikawa Prefecture on the Noto Peninsula.
With the small Wajimashi Mii closed recently, Nanao Korosa is the only operating ski area on the Noto Peninsula.
The ski area is south of the city centre and overlooks Lake Tane (the dam lake of Tane Dam).
The ski area opened in 1999.
This region is not known for heavy snowfall, so the ski season can be unpredictable. There have even been a few seasons when it could not open due to a lack of snow.
