I've lived in Tokyo for about 8 months now and I have, by far, learned quite a few things about the Japanese that distinguish them from other peoples. Here goes:
One: Unless you cause them physical harm or unduly disturb their peace, they will allow you to do whatever pleases you.
(Drunks just sleep wherever they want without anyone disturbing their trip to dreamland.)
Two: They like making things small, but still usable.
(Tired of the thousands of huge trains that they use for daily commute, these kids and their parents enjoy rides on small trains in a park.)
Three: They have strict quality standards for anything bound for human consumption.
(Read: Not fit for drinking. Seen at a rest area going to Mt. Fuji)
Four: They just don't run out of ideas to make life more convenient.
(This is Roomba: A cordless robotic vacuum cleaner. Complete with sensors, it cleans an entire area without any human intervention).
And Five: They conscientiously practice garbage segregation.
(Flyers advertising illicit services must be thrown in this box. They are deemed too dirty to be disposed alongside regular garbage.)
