Wearing mask is pretty basic so no discussion, but mask type is a bit controversial topic in Japan. At the beginning of pandemic, gov sends cloth mask all house. I think this was good try at the time, but finally the mask isn't used well because non-woven mask become available soon. Now gov still has huge cloth mask stocks. After that, some research suggests that nonwoven mask is the best for protect, cloth mask isn't the best, urethane mask is relatively bad. But because the gov sends and still has cloth mask, gov don't want to say avoid using other than nonwoven masks. Anyway over 80% (I assume) of people wear non woven mask so totally fine.
