Pre symptomatics are at their peak of infectious transmission before they show signs of infection a Korean study confirmed that via viral loads in the upper respiratory tract. Masks work on a mass scale Japan, Vietnam, Korea are all quantifiable examples of that. Japan never locked down despite having population density that exceeds NYC in nearly every Japanese city. The key difference is Japan has a mandatory mask use at all times everywhere. And it is part of their culture to use masks every flu season and any time they have so much as a sniffles the person masks up out of respect for their countrymen. I have been to Japan in early winter during peak flu season a few times and every time you see hundreds of people with masks they are an expected part of the flu season.

Yes, Japan has a high population density, as does a lot of Asia, and so, if their methods proved to be effective in combating the propagation of a coronavirus, it would make sense for an area that had similar density, like NYC, to adopt their method at least as a precaution. However, that isn't what we're seeing. We're seeing idiot governors and mayors in low-density areas demanding mask wearing to the point where people walking around outside, alone, feel obligated to wear masks. Logic, reason and utility are not coming into play with regards to masks.

Also, I'm willing to bet that Japan never sent Covid-infected people into their nursing homes. Roughly half of NY's deaths were attributed to nursing home deaths at one point.
