I have been browsing this thread to get some ideas for our upcoming flight. We arrive in NRT 9:35 am and depart at 4:55 pm. We have never been outside of the airport in Japan. I am thinking we would have enough time to visit Narita. We are obviously a little nervous about it, not knowing the area or the language. We do have use of the United lounge (I don't think the Polaris lounge is open yet) but sitting there for 6 hours does not sound appealing. I am going to try and talk my husband into taking train to Narita for a couple of hours. So, I have a list of what we need to do- go to arrivals, not transit, get currency exchanged (how much for lunch and possibly a few souvenirs?), put carry on bags in locker?, get train passes. For a 4:05 pm boarding time what time should we leave Narita?
