Japanese men seem afraid of women in general and have a need to infantalize them so they can consume them. There is a big culture of illustrated child porn there, it's out in the open, everywhere and normalized like no where else. It's retweeted on twitter by otherwise normal seeming illustrators/people, though it would disturb most people outside of Japan. The culture of cute, kawaii things is just as obvious in it's sex industry as it is in everything else, although in a very horrifying way.
