Hikikomori is a term used in Japan to describe people who act as recluses and rarely leave their houses, preferring to spend their days and nights usually on the internet, especially on Japan's 2ch. Since such people hold no job, they state their occupation as 'hikikomori', which literally means 'home security guard' as a means to sugar-coat their unemployment, and generally nerd, status.
