Are you saying Japan has a more relaxed stance on porn? Don’t they have government mandated censorship of nude images? I would call that more strict, not less.
IMO, the way it is that hard distinction between child and adult is simply not understood. East Asians in general age in way more linear and continuous manner than Europeans for whatever reasons, and that makes it just harder to agree that some people aren't like others.
Genital-censorship laws in Japan are a fig leaf, barely ever upheld, afaik.
They are absolutely more relaxed with the type and amount of content getting published, and have been for a very long time. The likes of Miguel Angel Martin in Japan would be considered average, whereas in the west they shock the mainstream.
The anglosphere is still somewhat conditioned by the idea that comics are for kids; at the other end of the spectrum, the francosphere expects every comic to be an auteur-level masterpiece. East-Asians just see it as a product to sell: as long as they are correctly labelled, so that strong material ks not missold to kids, everything is fine.
I'm not a christian, but I wouldn't call this judeo-christian morals, just puritanism and purely an American mindset that is completely alien in other Western (mostly christian!) countries. I also don't associate puritanism with Israel either, so the "judeo" part is another misnomer.
the lack of judeo-christian moral nannyism hardly means a dangerous society but a peaceful one
just look at all the accusations on X and calling Japan weird and worse
