But he didn't make a statement, he asked a question about why the previous poster mentioned Japan with regards to extraversion when they have such a thing as hikikimori. By comparing the two he appears to be suggesting that hikikimori are just introverts, and as such proof that Japan does in fact have a cultural obsession with extraversion. It's not the assertion that Japan is a largely extraverted country that I took issue with (though I would say it is debatable), it was the (it seems to me) equating of introverts and hikikimori. I just wanted to point out that hikikimori are not introverts. Introversion is not a mental illness. Hikikimori may very well be, depending on the individual. I find that most people have a poor understanding of the introversion/extraversion spectrum and wrongly attribute things like social anxiety, timidity, lack of confidence agoraphobia etc. to introversion. Then again I may have misunderstood the point of his question and read too much into it.
