How long of a walk is it? I arrive the day before my friends do for a tour of Japan, so I'm staying at the NRT Hilton that "early" night. My flight arrives at 3:20pm. Their flight arrives at 2:00pm the next day, so my plan was to go to the hotel for the night, then meet them the next day at the NRT Express before we head into Tokyo. That leaves me with the morning, and possibly part of the afternoon, and I was DEFINITELY interested in seeing the temples...
