The name comes from Arosa in Switzerland, its sister resort. It is about 15 minutes by car from central Nanto, and a gondola takes about ten minutes to reach the summit, where beginner and intermediate runs split off. Night skiing runs mainly on Fridays, Saturdays and Sundays in midwinter. Sources: info-toyama.com, iox-arosa.jp (sources read 13 Oct 2026; an AI draft the site operator has not yet checked)

The quality score leaves out how much snow falls (it uses temperature, frequency, rain and wind).
