Hello
I would like to take the sleeper train from Sapporo to Tokyo (Hokutosei or Casiopeia) at the beginning of my trip.
I have a JR Rail Pass, but do not want to activate it until the day that I take the sleeper train, which will be my first journey using the pass.
But I have read that this train gets very busy and that it's very important to reserve it in advance.
Is it possible to make an advance reservation for the train before I have exchanged my XO for the Rail Pass? If so, how do I do this?
Also - does anybody know how much the supplement is for the sleeper train?
Many Thanks
Ali
