I am traveling to Japan this summer, but I am unsure if a 21 day JR pass would be worth purchasing for my itinerary.
I am staying with friends who live in Shinjuku and Tokushima for a portion of the trip. My itinerary is minimally flexible, but I would gladly take as much advice as I can get!
For the days that I am traveling within a certain city, I hear that there are not very many local JR lines, so I anticipate that I would be spending a lot on transportation for each location. Is there a rough estimate on how much people spend on local lines that aren't be covered by JR?
Day 1: Arrive in Narita Airport -> Shinjuku/Tokyo
Day 2-6: Tokyo (Day 4 will be traveling from Shinjuku -> Mt. Takao and returning back to Shinjuku after hiking)
Day 7: Day trip from Shinjuku/Tokyo -> Chichibu (will return to Shinjuku the same day)
Day 8: Shinjuku/Tokyo -> Kyoto
Day 9-11: Kyoto
Day 12: Kyoto -> Osaka
Day 13-14: Osaka
Day 15: Day trip from Osaka -> Nara (will return to Osaka the same day)
Day 16: Traveling from Osaka -> Kobe (may possibly return to Osaka the same day)
Day 17: Traveling from either Osaka or Kobe -> Tokushima (visiting/staying with a friend)
Day 18: Tokushima
Day 19: Tokushima -> Shinjuku/Tokyo
Day 20: Tokyo
Day 21: Departure from Shinjuku/Tokyo -> Narita Airport
Thank you so much for your help!
