After watching Welcome to the N.H.K., it got me wondering if this story had been based on a real conspiracy.
According to Wikipedia,
[...] The story revolves around a 22-year-old asocial individual who gets aid from a strange girl who seems to know a lot about him, despite never having met him before. A common theme throughout the story deals with the hardships of life and how people must deal with them in their own way.
In Japan, NHK refers to the public broadcaster Nippon Hōsō Kyōkai, but within the series, the main character believes it stands for Nihon Hikikomori Kyōkai (日本引きこもり協会, The Japanese Hikikomori Association), which is a reference to the protagonist's claim of a subversive conspiracy led by NHK (the real-life broadcaster) to create hikikomori.

I haven't read through the article about hikikomori's yet, but as far as I remember, too many people end up living in seclusion in Japan for it to be just a coincidence.
Was there ever a conspiracy or claims that there might be a company or organisation that would promote people to live their lives in seclusion?
