Hi
I will be traveling to Japan with my family (6 adults total) arriving in Tokyo Narita on mid-October. We plan to stay in the Shinjuku area and stay 3 nights in Tokyo and explore Tokyo and surrounding areas and then we leave Tokyo for Hakone where we will stay 1 night. Then we leave Hakone for Kyoto where we will stay in a hotel and spend 2 nights and explore Kyoto and nearby Kobe, Nara, and Osaka while we are there
We plan to leave Kyoto and spend 1 night at a hotel near Osaka Kansai airport and leave Japan the next morning
Question: Should we get a 7 day JR pass or is there a more economical way for us to use the rail system? We will mainly want to take the rail everywhere we go since my mother-in-law cannot walk very far due to issues with her legs.
Also, does all the JR trains have first class and if I get the first class tickets are the seats reserved?
Thanks for your help
Peter
