Hikikomori
7% of the male population in Japan is called "hikikomori." This term means that a person rejects social life and prefers total isolation. Such people often don’t have a job and depend upon their relatives’ income. Some hikikomori are isolated for years or even tens of years.
"Japanese people traditionally make snowmen with 2 snowballs, not 3 like the rest of the world."
