Okay folks, I'm going to upload the research paper I wrote last year that does a survey on hikikomori topic. It's in PDF format and around 800k; feel free to peruse and use for your own work and articles, I only ask that you properly cite me as it's author if you do choose to use my content in an article, web page, or what have you. Professional courtesy and all that.
Note that this paper was written purely with available resources here in Hawaii at the time, so I had not yet done my field research at the Takeyama Gakkoh hikikomori rehabilitation center in Japan.
Feedback is welcome either via my email or in the comments for this entry. I'll check back occasionally and respond to any questions.
I'm also going to post the link in my Typepad links on one side of my blog so it's always available.
