I have a 12 hour layover in NRT on 20 Oct. and need some advice on what to do to kill the day there. I am willing to leave the airport for a few hours.
Also, if there is anyone who can assist with lounge access, I am flying AA...for the first time on 10 years I do not have high enough status to get into a lounge

This could be ugly and I would appreciate any advice and assistance.
Thanks.
