> I live in Japan and everyone here wears a mask, but more importantly, wears them properly
I lived in Japan, and have many friends in Japan. This is true only if you redefine "properly" to exclude all indoor environments. People in Japan routinely gather inside without masks, then put them on when they go outside. You can watch the TV news and see people gathered in bars and restaurants with masks off, but then they wear them religiously while walking around the city. Absolutely pointless behavior. I see this behavior amongst my own friends regularly on Instagram and Facebook.
Moreover, it's fairly common to see things like "chin masks", like this:

I'm not sure what these are supposed to be doing, exactly, but sure, I guess people are "wearing masks".
> Many Japanese people are already attuned to wearing them during flu season, and everyone wears them if they think they are getting a cold
This wasn't even close to true, pre-pandemic. I was regularly sandwiched between people on trains with obvious head colds, sniffing their snot every 5 seconds. Sure, some people wore masks, but it wasn't "everyone". Not by a long shot.
> Masks are, of course, effective.
This is an assertion. The best available data from randomized controlled trials shows a minimal effect:

> Masks work.
Repeating this phrase, without evidence, does not make it true. Even ignoring the top-line RCT evidence, you have to define what you mean by "masks" to get close to a meaningful statement -- a chin shield is obviously nothing like a cloth mask, is nothing like a full-face respirator.
