I had some help from staff at Narita airport. But it was quite easy to use. Just select option exchange at the ticket machine, and scan QR code. Select number of tickets to redeem and select train time and seat location. And that was it, ticket printed and off we went.
So easy and love discount! Highly recommend .
The process is simple and fast. Thereafter the ticket exchange at the vending machine is easy as well. Will buy again. Hope Pelago can offer more Japan Railway ticket sales, eg, JR East, JR West, ....
Actually easy to claim. Just show QR code to the staff and they will exchange to tickets.
