I am arriving in Tokyo on 12 November early in the morning and departing on 22 November in the morning. I have visited Tokyo several times and would like to know if someone could recommend an itinerary that brings me to the Nagano/Niigata region. I also intend to buy the JR East - Nagano Niigata Pass which allows me to travel on 5 flexible days over a period of 14 days. Is that advisable? How and where would you recommend that I spend the time given that I would like to spend at least 21 and 22 Nov in Tokyo and at least 3 days in Nagaoka (between 12th and 18th November).
