Arrived NRT T2 4pm Friday. Our JAL from NY did not offboard transit passengers first. I was First off the plane but as started walking another plane had just emptied ahead of us. Exited immigration 4:45. There were 8 moveable kiosks on the line but before immigration to do fingerprints and picture. This helped speed the line. Smart.
while on the line I looked back and saw that end of line was about 50% longer than when I entered so somewhat lucky I think to have cleared immigration so quickly. Much better organized and staffed than when I entered Japan early January and it took 1.5 hours to clear immigration.
