We will be in Japan for 20 days. My question is two part: Should we get a 14 day or 21 day JR pass and is it worth paying extra for green car. Someone mentioned that not all trains have green cars. Our itinerary starting Oct 21/2013 is as follows:
Arriival Narita
4 nights Tokyo with side trip to Nikko
Nagoya
Nagiso
Takayama
Kanazawa
Kyoto with side trip to Nara
Kinosaki
