Tokyo Wide Pass

hi, i would like to purchase Tokyo Wide Pass. Understand the reservation of the tickets only open one month in advance, but there are websites (such as Klook) who are already taking the reservation. Will there be situations where the seats will be run out by the time we go into the JR Websites to reserve when the date is released? Many thanks

When are you traveling that you are so concerned about getting a seat that you are willing to pay the extra cost that Klook will bill you?
Yes, some trains sell out, most don’t and if you can buy the ticket a month in advance you’d need to be talking about a very special train for it to sell out within hours.

There are some travel companies that "claim" to buy tickets for you more than one month in advance, not just for trains, but other events as well. It is simple - they lie.
