Stereotypes don't really help as we don't know which of them matter if any, and to what degree. Japan also had mask shortages as they got most of their supply from China. They also depend much more on public transit and have smaller housing and public places. I want stats. For all we know it could be the amount of plosives and spitting in different languages that's the key. By the way I don't know about you but I can't remember the last time I hugged someone outside my immediate family, and I may have shaken four hands in the last 12 months. I have a hard time believing that's very relevant, despite the high profile of such customs.
