It's a sad reflection on the state of safety in many of the world's cities but...this is quite tame. I think the question is: what are the chances of being a target in the worst crimes, which are being randomly assaulted/mugged/murdered/raped. From the women I know who have been to Japan they've recounted that it's one of the few countries they felt safe (in most areas) walking home late at night. Of course, that attitude probably leads to a few bad outcomes occasionally.
Again, I think Japan is one of the safest countries in the world. I'm mainly addressing the parent's comments that they've never seen crime in Japan and sometimes the meme in Japan that there's no crime at all.
