In reading the following, bear in mind I was walking around with a 102F fever, having just gotten off a 13 hour flight, which was preceded by a 3 hour delay on the tarmac, which was preceded by a multihour layover in Chicago, which itself followed a flight in from Boston for which I had to get up really early to catch.
Because as I was walking through Narita airport from the gate to customs, I happened to have looked through the windows to the departures' area foodcourt, and immediately thought to myself, "Gee, this airport has a lot of Japanese restaurants."
