We recently spent a month in Tokyo. It is ridiculously safe and law-abiding. I'm surprised they have any crime at all. In our entire time there, I saw one (1) individual piece of small rubbish on the street.
Tokyo is not safe. People who are arrested for suspicion of crimes are held for weeks by the police and threatened and beaten and tortured until they confess, even if they are innocent. The police then release them for 24 hours and rearrest them on a different charge so the two month holding timer resets.
People there have been held for months in solitary confinement (torture past a few days, per the UN) awaiting trial only to be found innocent and released.
As a foreigner, good luck if a Japanese person calls the police on you and accuses you of something. You’re looking at 40+ days of beatings and torture as the police will of course believe natives over tourists.
