Good morning. I am travelling to Japan arrive 16th Dec at 5.30pm. We check into Ks House Hakuba on the 17th however not until 3pm. So I am thinking taking my kids to Snow Monkey park. We have to be at Nagano station to meet tour guide by 8am. Then on 22nd Dec we plan on going to Hakone. Is it worth me getting a JR pass. Can we do it cheaper by normal rail, trying to save money that is all.
