The low case fatality rate in Japan can probably be explained by the fact that nursing homes in Ontario and Quebec were coronavirus killzones. Japan probably did a much better job of protecting nursing homes. And in Japan it's customary to have your elderly parents live with you. While multi-generational homes leave the elderly vulnerable to COVID relative to living alone, the elderly are much safer living with their adult child's family than living in a nursing home during a pandemic.

The Japanese elderly are also more healthy than the American elderly. Far less obesity, heart disease, diabetes.

I was reading in an article back in March in the South China Morning Post (Hong Kong-based paper) that Japanese doctors were using hydroxycloriquine to great results. But the western media shit all over it. Thing is, the elderly Japanese are far more healthy than elderly Americans. So the heart-related side effects of the drug are far more likely to kill a fat fuck obese American with heart disease than a thin healthy old Japanese man.
