Japan has managed to keep the rate of infection low in spite of having some very densely populated cities with crowded subways, and having been overrun with Chinese tourists prior to February of this year.
There is very little handshaking or hugging in Japanese culture, just bowing. I also find myself wondering if this could have something to do with their very elaborate toilets. I don’t want to be overly graphic, but everything has been thoroughly cleansed in Japan long before toilet paper is ever deployed.
Japan is very clean. As opposed to China which is filthy.
