Hi, i'm a bit confused about is this train covered by jr pass or not?
Jr yosan line limited express
Jr ou line limited express
And which train do i need to make reservation? As far as i know is train from tokyo station to sapporo station .. can you tell me what's more routes that i need to make a reservation? (I mean, if i don't make a reservation first, i won't be able to ride the train because all seats are reserved seat, no unreserved seat)
Thank you before
