I brought up in Nagano. Nagano has many ski resorts. One unforgettable place in Nagano is called Karuizawa. Many tourists visit there in summer to cool down because Karuizawa in summers is very comfortable weather. In winters people visits for skiing. I took a bus from Tokyo to Karuizawa on my way to my home town in December 2017. It was already snowed. I took a Shinano tetsudo to my home town.
Just wonder it is snowing now in Karuizawa. If you love the winter why not visit Karuizawa!!!
