1. drinking culture
AFAICT drinking culture is fairly different in Japan than in at least the USA. In the USA drinking leads to fights and violence. In Japan that seems far less so. Drinking and getting drunk in Japan doesn't have the stigma it has in the USA because it doesn't lead to the same issues? Include drunk driving in that since few people drive
2. attitudes toward drugs
SF is falling apart. I know you can argue the two are not related, SF falling apart and SF being one of the most drug friendly cities but I'm sure the Japanese don't find it quite so easy to separate those 2 things. I'm not 100% sure I can. Like many of the things that seems at least mildly related. The lower violent crime. The lower theft rates. The more respect for the commons (less trashing public things). For whatever wrong headed reason I find drug culture and trashing things related.
