A tip: When boarding, don't be one of the first four people to board the aircraft in NRT. You will definitely be pulled aside for a "random" security check. If your number five you will be the first one on board.
Great tip and you are exactly right. My mother is a wheelchair assist,so I thought it would be great to get her on first. She went in without me and I was stuck with "random" security check.
