I do not trust any stats that come out of Japan in terms of homelessness. If there's a statistic that's embarrassing for Japanese society, you know damn well they're gonna try to cover it up with technicalities.
In Japan, the legal definition for someone who is homeless is: "those who use city parks, riverbanks, roads, train
stations and other facilities as their place of stay in order to live their daily lives."
So that doesn't include living in your car, living in insecure housing, living in shelters, or living in internet cafés, of which in 2020 there were about 15,000 'net café refugees' in Tokyo alone.
Sooo yeah, Japan can claim to officially have a super low homeless population, because they've narrowed the definition so much that you have to literally be sleeping on the street for it to count.
Your unhoused numbers are wrong. Those are the official "sleeping on the streets" numbers, which is not the same thing. First because they're official, and therefore almost certainly undercounting, and second because they exclude all of the situations where people don't have houses but are kinda not exactly in a cardboard box.
correlation is not causation, the reason why they have less murders is probably not Christianity (for example they have way stricter gun control)
edit: after rereading the post I don't think the other person is tryng to argue that Christianity is causing murder and whatnot, so ignore above paragraph
also wouldn't it make complete sense for Japan to have way less Christians since they were isolated for so long and have their own religious beliefs
Given the confluence of weeb culture and the alt-right (think incels and “traditionalists” with anime avatars, right-wing gamers pointing to Japan as a high-tech conservative utopia untouched by wokeness and such), it was inevitable that sooner or later someone would try to imagine a Japan that goes to Latin Mass.
