I will be leaving for Tokyo on 27 Mar and have just bought a 7-day JR pass for my itinerary as follows:
27 Mar - arrive Tokyo at 4.20 pm
28 Mar - Tokyo-Osaka (stay 4 nights in Osaka and plan to do a day trip to Kyoto, visiting Arashiyama, a day trip to Nara, a day's visit to USJ and spend the rest of the time in Osaka
1 Apr - Osaka-Nagano (stay 2 nights in ryokan in Yamanouchi and plan to visit Jigokudani Monkey Park and surrounding areas. Not sure if I would have time to do a day trip to Takayama and Shin-Hotaka robeway. Could you advise please?)
3 Apr - Nagano-Tokyo (stay 5 nights in Tokyo and plan to make day trip to Mt Fuji and Mishima Skywalk , possibly Gotemba, Mt Takao, Odaiba, etc)
Could you advise me if my 7-day JR pass works with this itinerary and would I have to incur any additional costs for my travels?
I checked HyperDia but do not quite understand some of the fees indicated for example travelling on the limited express Thunderbird 11 from Shin-Osaka via Kanazawa to Nagano, there is a fee of JPY7880. Do I need to pay this fee and what does it mean when "reserve" is stated?
Not sure if this is the best plan to include Nagano in my itinerary owing to the long travelling time and the number of transfers, or is it more ideal to spend the 2 nights (1-3 Apr) in some other places in the eastern part nearer to Osaka side. Need your expert advice on this.
Please also tell me what attire would I need to wear at this time of the year? Do I need winter clothings for Shin-Hotaka robeway and Mt Fuji?
Thank you for your help.
