Earlier quoted context omitted.
The largest metro area on the planet, Tokyo, 34 million people, is also the one of the safest with the extremely low crime. Seoul, and Singapore are both around 10 million and are also safe with low crime.
Japanese criminal procedure is … interesting from what I can tell. There is a very high conviction rate, suspiciously so. Singapore is questionably democratic, utilises corporal punishment and is described by some as a police state. I think it’s fair to say that while a strong sense of community ethics may be present in Singapore, it’s certainly not the only thing holding people in line. Seoul I know little about.
USA, each suspect is registered, then suspect gets acquitted. Stats show 100 suspects, 50 acquitted = 50% convicted. Japan there is no suspect registered unless they're already sure it will stick. In other words they've already done the investigation. So 50 suspects = 100% convicted because the 50 that there wasn't enough evidence for were never even registered as suspects.
> Only about 8% of cases are actually prosecuted, and this low prosecution rate is the reason for Japan's high conviction rate.

If true this makes sense some cultural sense. Japan is super privacy conscious. It's Japan that got google maps to remove people's faces from street view. It's also illegal to take pictures of people in public. Being labeled a suspect would mark someone unjustly if it turns out are not likely guilty. No actual idea of that plays into the difference. Just thinking out loud.
