Japan is mostly a normalfag country, there are tons of fem-ales, stupid normies, retarded trends etc, I would say that 90% of Japan is pure normalfaggotry, like any other country.
The magic happens on the other 10%, there's a real, sizable part of the population that is composed by shutins, NEET, virgin, otaku, rejected by society, individuals, but contrary to other countries that would just ignore, forget or just ostracize those people forever and don't pay any attention to them Japan has created an entire industry to cater to these people, and I would say that they don't only cater to them, but they actually provide continuous and endless material to satisfy them, be Anime, manga,eroge, dakimakuras, figures, porn and other things, designed specifically for those people, I would say that Japan has perfected the art of escaping reality as much as possible, if you think about is truly wonderful what they have done, I think that's the reason why so many people with similar characteristics is attracted to Japan, some years ago some serious studies about this have started to appear, I think it's a very interesting topic.
Just look at this manga
>>42176 on any other country writing or reading this would probably get you in prison the second you tried to do it in public, yet in Japan is relatively normal to engage with this kind of material, I will never forget when I was in surugaya in akiba on the floor full of eroge and the customers were buying those things and the employeers were ordering these massive posters of lewd character as if it was perfectly normal, because there it probably is.
