Hi!
Me, my friend and my sister are going to Japan on apr 29. We're arriving on different airports. Me and my friend will arrive in haneda airport. And my sister will be arriving in narita on a later time (Her point of origin country is different from ours). We are planning to take the izumo sunset train from Tokyo on May 2. I'm hoping that there's still seats available. Can I activate my sister JR pass so I can book all 3 seats? I'll be purchasing all JR pass. I can get a copy of her passport.
Thanks.
