Hi Sir
I am planning to travel from Tokyo to Hokkaido by purchasing the JR East South Hokkaido pass as soon as I arrive in Narita Airport. However, I am worried about the seat availability and want to make the reservation earlier. I came across a website and it said you can make JR pass purchase and online reservation at the same time outside of Japan as long as the departure is within a month.
Below is the link, please advise if this is a new service offered by JR or if it is a scam?
