During the pandemic, yes. Not so much after. I live in S.E. Asia and have been to a large number of countries in Asia, and I can't say I've seen extensive mask usage anywhere except for Japan.

Of course, it's much more common than Europe or the US, but it's still in the single digit percentages.

This was before the current pandemic of course. But eve today, in Singapore, I'd estimate 15% to 20%?
