I am travelling to Japan from Uk and land on the morning of the 26th April 2014 at Narita. It is very important that I am able to leave for Kyoto in the morning of the next day and I have concerns that the Shinkansen trains will be fully booked due to Golden Week.
I will be pruchasing a Japan Rail voucher which I won't be able to exhange for the pass until I am there, so I was wondering if there is a way to reserve seats from UK using just the voucher??
If this is not possible, is it likely that the train is going to be full if i don't get chance to reserve a seat until the afternoon when i can get to a Midori no Madoguchi office? Is there one at Narita?
