We went to Nagano, Gunma and Niigata for skiing in Golden Week holidays. Some ski resorts where has a lot of snow fall in winter season, open ski runs until the Golden Week holidays.
Actually, we went to Shiga-Kogen in Nagano, Tanigawa-Dake in Gunma, Ohara, Okutadami and Hiuchi ski resort in Niigata. We enjoyed not only skiing, but also nice viewing, good hot springs and local foods.
Here's very beautiful viewing from Tanigawa-Dake ski resort
And from Ohara ski resort.
