I have passed through Narita Airport Tokyo 8 or so times. From the time they had just started to renovate the airport to the new modern terminal. The old round terminal I recall as dark and dingy. The new terminal modern and clean and busy. I do not recall many places for snacks or food. Most of what I recall of Narita are the shops in the terminal. I have never had a bad experience flying through Narita. Security at Narita I did find very good. One of the first airports that were really on top of it.
