Some fact about hikikomori

okay...known japan better...
this time i wanna talk about hikikomori

The Japanese Ministry of Health, Labour and Welfare defines hikikomori as people who refuse to leave their house, and isolate themselves from society in their homes for a period exceeding six months. While the degree of the phenomenon varies on an individual basis, in the most extreme cases, some people remain in isolation for years or even decades. Often hikikomori start out as school refusals, or futōkō (不登校) in Japanese (an older term is tōkōkyohi (登校拒否)).

common traits
While many people feel the pressures of the outside world, hikikomori react by complete social withdrawal. In some cases, they lock themselves in a room for prolonged periods, sometimes measured in years. They usually have few, if any, friends.
While hikikomori favor indoor activities, some venture outdoors on occasion.The withdrawal from society usually starts gradually. Affected people may appear unhappy, lose their friends, become insecure, shy, and talk less

prevalence
According to psychologist Tamaki Saitō, who first coined the phrase, there may be one million hikikomori in Japan, representing 20% of all male adolescents in Japan, or 1% of the total Japanese population. Saitō later admitted in his autobiography (Hakushi no kimyō na shishunki) that he made up this number to draw attention to the phenomenon and that it had no factual basis.[citation needed] He had based the figure on the number of people with schizophrenia in Japanese society. His clinical work had convinced him that there were at least as many hikikomori
