Gender equality has a long way to go in America as well, so what's your point? There's a huge percentage of unreported rape in America too. No matter where you go in the world there's a lot of stigma about rape, and women often feel too ashamed of themselves to tell anybody about what happened. There was a story on my local news just a little while ago about a woman that got beaten and raped on the subway platform here in NYC, despite that she ran up the steps and was screaming at the MTA attendant in the booth to help. The guy just stared at her and did nothing. Well, he pressed a button that summons the police, but everything was long over by the time they came. That's their policy for what to do if something illegal is happening in the station - just stay in the booth. I think it's pretty messed up. The point is, there's really messed up stuff that happens everywhere.
I didn't say one thing or the other about statistics. Just that there's this attitude that people have about Japan that is either "lol Japan" or "wow, Japan is so fucked up". The topic you linked to exemplifies that. I don't care about defending Japan, but people shouldn't encourage ignorance. The reality is that the Japanese are just as boring and ordinary as anybody else.
