I was wondering if you had to go through passport control in order to use the day rooms? I see a map of the airport but can not tell if you can access it without going through security. What about the shops & restaurants?
The reason I am asking this is, I have a long layover at NRT but am switching airlines and wont yet have a boarding pass for my flight back. My flight arrives at 6am & I don't depart until 4:45pm. I don't know if I can check in that early for my flight or even if the airline employees will be there yet.
