Tokyo Airport is big and beautiful.  Lots of people walking around at all hours of the morning.  I arrived yesterday at 8 pm and it is now 1:38 in the morning.  have been dozing, and of course people watching.  I’m impressed by the courtesies here, such as bowing when people interact with one another.  It appears to be a gesture of respect.  Plane rid was 13 hours with about 3-4 hours of sleep, a few movies and some pleasurable reading.
