What Japan lacks in rubbish bins and benches, it makes up for in lockers and laundromats. That is a legitimate reason for me to stopover/layover at NRT/HND when traveling between the US and East Asia.

I don't mind checking a bag now that I have *G status, but flying back to the states is a pain in every sense. Average wait times of >30 minutes at JFK and EWR baggage carousels-brilliant.
