Japan is a monocultural civilisational state. That is a big factor.

American children are in more danger because the country's more diverse?

It is the difference in culture. In big cities, Japan doesn’t tolerate public deviance. Police are visible in every block. They are very strict about weapons; you can’t bring a knife in public for no reason etc.

		They also have a culture of enduring things in silence for the greater collective good. For instance, most girls and women will have stories of harassment, especially by men on crowded trains but almost none of them will do anything about it.

To his point - I would say, it's a bug factor BECAUSE on average their culture seems more safe. But it's not because it's monocultural. Bad "monoculture" is bad, good one is good, nothing complex there. Simplifying, but that's pretty much what is said

Diversity doesn't make places more dangerous (if i understand the stats). But humans are naturally tribal and fear those who look and act significantly different.

That depends on an arbitrary perception of 'my tribe'. Irish and Italians used to riot against each other. Germans were hated (look up a quote from Benjamin Franklin). Protestants and Catholics used to riot. Every wave of immigrants seems to get the same treatment by some.

Within a few generations, their decendants marry each other.

Because humans are tribal they will also go on to attack and prey on those who are outside their tribe, making diversity more dangerous. Especially when diversity is not merely some people of different ethnic/racial backgrounds living and working together, but a population split into isolated cultures with different circumstances.

Unless there's a big strict enforcer to keep everyone in line of course.

		This is something a lot of people seem to believe that is not borne out in the research. Plenty of specific counter examples like Queens NY, a densely populated and exceptionally diverse place with crime rates comparable or better than many much more homogenous places in America. Poverty and income inequality are much better predictors. I felt this reddit comment from a while ago did a pretty good job rolling up sources on this: https://www.reddit.com/r/TrueUnpopularOpinion/comments/1jxff...

Russia is fairly mono cultural too. Is it safe?

Yes. Russia is inarguably safer in terms of street crime than the USA.

Philadelphia in 2025 had a higher murder rate than Belfast during the height of a civil war.

Crime in the USA is also extremely regional and local in pattern.

		I don't think numbeo can be a good source, it seems to be self reported metrics. I asked it for comparison of NZ to USA and it told me that NZ was about the same or worse on most numbers. But actual crime rates are lower in NZ. The murder rate is 5x lower.

		> Philadelphia in 2025 had a higher murder rate than Belfast during the height of a civil war. Do you have a cite? In American cities crime is at generational lows, including / especially murder.

		Oh no, no way. Child violence on the streets and in school is WAY higher, it's ingrained in culture. It's also pretty rare if a Russian kid would tell his parents about it (only if property damage is involved). I don't know how your link gathers data (website only shows one dude, software engineer, not a professional survey statistician), but from personal experience I can surely say it's rankings are BS. The closest in US are the "bad towns" like East Palo Alto or some neighborhoods of Oakland, with their respect for ex-cons and prison slang.
