Hello,
I am flying into Haneda on a Sunday morning and plan on going to Osaka the same day. I would like to reserve Shinkansen seats. Do I need to wait until I arrive at Haneda and activate my JR Pass before I can make those reservations? Or is there some way I can make the reservations ahead of time and still use the JR Pass (instead of paying for separate Shinkansen tickets)? Thanks.
