I am planning for a 2 day trip to Nagano, Please suggest me the best places to visit in December. Please reply to my question as soon as possible
Thanks for your question. For sightseeing in December, no area of Nagano is more popular than Jigokudani Yaen Koen (Snow Monkey park). Here you can see wild monkeys bathing in hot springs in a valley covered in snow. The nearby town of Yamanouchi is a wonderful place to stay and relax in local hot springs (monkey free!).
I hope that helps answer your question.
