Can someone please explain the JR pass to me. I land at Narita terminal 1 and I'm traveling to Tokyo station. So when I land I need to valid and exchange my 'exchange order' for the JR pass, where do I do this? I then need to get the N'EX to Tokyo station, I think I need a reservation for this trip, is that correct? Where do I reserve my seat, same place that I exchange my pass? Do I have to pay for a reservation? Will the reservation be easy for me to read?
Any info would be great.
Thanks in advance.
