However, I would partly disagree when he says: “It’s very rare to find hikikomori in poor families” and ‘Majority of hikikomori are graduated people, after graduating university they became hikikomori.‘
I met hikikomori subjects from poor families who didn’t go to university (see my article in Subjectivity).
It does not mean that they are the majority. But let’s not forget them.
Counter arguments to Kato’s claims could also be found in Uchida and Norasakkunkit (2015) recent article: “Sometimes NEET and Hikikomori are perceived as resulting from overprotection by upper-middle class parents who can afford to pay their children’s living expenses, but our results suggest that this is largely not the case.” Total number of survey respondents of study 2 was 10,744 and their article is open access.
Japanese high-school dropouts are abandoned by society (see my publication)
Most of hikikomori subjects do not consult psychiatrists: psychiatrists only meet with a minority of hikikomori cases (see my review) and hikikomori subjects attend NPO activities where psychiatrists are absent (see my article in Subjectivity).
