I will arrive in Japan (Narita) on a Monday, and take the NEX to Tokyo.
I will then visit Tokyo, Osaka, Kyoto and Nara. I will ride the JR from Osaka to Tokyo then to Narita via NEX on the following Monday, and leave Japan from Narita. That's a total of 8 days (Monday to Monday, inclusive). I plan to buy a 7 day JR rail pass online before traveling to Japan.
Since I will stay in Japan for a total of 8 days, my question is which 7 days should I activate the JR pass for? Should I pay for the NEX ticket to Tokyo upon arrival, and activate the 7 day JR rail pass for Tues through the following Monday? Will that be the best use of the 7 day pass?
Thank you for your answer in advance!
