Dear Daniel San,
I have my flight arrive in Haneda Airport late night and plan to overnight in the airport and exchange my JR Pass the next morning in the airport. I have checked the JR website and it stated as following:
Haneda Airport International Terminal JR EAST Travel Service Center
(Tokyo Monorail 2F Ticket Gate/Arrival lobby) 7:45-18:30
It is quite different from what I learn before from other posts which the office only open at 11am for JR pass exchange, can I please clarify this with you the exact office opening time? If yes, can I use the JR pass to Asakusabshi Station?
Thanks,
Mei Ling
