Many peoples on the earth regard Japs as very creepy, because as usual the Japs refuse
to communicate with foreign people, even overseas.

Japanese immigrants frequently inhabit by themselves, and make their own closed community.
They are clearly unwilling to communicate with the native people and to
adapt themselves to habits of the land.
In Japan there seems to be no proverb such as “When in Rome, do as the Romans do.”

I’m of the opinion that the reason of such isolationism of them comes from
their lack of communication skills, or their xenophobic racism, or both.
