I can say the same thing when you see a stranger entering your property that such case alone can be a crime in the Japanese law. I have seen Japanese people reporting such crimes.
> But what do you think is, say, the date-rape report rate for Japan vs. any other country? Something that's already a source of personal shame is hard enough to report; knowing that no investigation will even be attempted in response means there's no reason to try to overcome that shame.
Even in such specific type of crimes that is very difficult to investigate, some people report to the police. It is up to the police department to accept the reports and further investigate.
> Look at what reports ever get any detectives assigned to them, and the statistics will tell a far different story.
Your claim was that nobody bothers to report, but I oppose to the claim because I have seen people reporting, and thus I still conclude your claim is false.
