Should you find yourself passing through Terminal 2 at the Tokyo Narita Airport, this helpful (although somewhat dated) video posted on Youtube would be worth watching. Just in case you are not familiar with the Narita Airport, Terminal 2 is home to Japan Airlines, several Oneworld carriers plus Air New Zealand, EgyptAir and China Southern Airlines. It consists of a main building plus a satellite building that are connected by concourses and a shuttle (people moving) system. Check-in, departures and Immigration are on the second floor while the baggage claim and customs are on the first floor.
Finding your way around the terminal should not be much of a problem but just in case you think that you might be in a hurry, watching this helpful video before you arrive might save you some time and from getting lost.
