I arrive in Tokyo on 26 September 2018 - stay for 6 nights and get a 21 Day Japan Rail Pass to be activated on 2 October.
My itinerary for using Pass is:
Kyoto - Khaosan - Hiroshima - Miyajima - Kanazawa - Takayama - Japan Alpine Route - Matsumoto - Nagano - Nikko - Tokyo
Not sure if I will be able to visit Nagoya logistically with the Pass.
Could you please critique my route for viability and costing?
