We are planning to ski from Christmas Eve and would like to ask the best place for snow during this time in Nagano that has
-Ski in / out accommodations and ideally western serviced apartments / chalets vs hotels as we may want to do some cooking.
-availability of English speaking ski and board lessons
The Hakuba Valley and Nozawa Onsen are both international ski resort areas that have snow during late December. You can find more information about them on the Classic Resorts Japan website.
Let me know if you have any other questions.
