I believe I have most of this process understood but...
I order my 7 day pass...an exchange voucher is delivered.
I exchange it at a JR booth at a station and confirm start date. eg. Arrive 15th March, exchange but confirm start date as 21st March. Correct?
I then just get on a train on 21st and go where I want? Or do I have to arrange to be on a certain train eg. From Hakuba to Osaka? Not worried about reservations but do want to get on trains when I want to get on them.
Please confirm my understanding
Thank you
