Which sounds more natural, A or B?

A) Most of the people in Tokyo wear masks.
B) Most of the people in Tokyo wear a mask.

Should we use the word of mask as singular noun or plural noun in this case?

@_choco_choco_ English can be weird and vague with phrases such as this. Both are equally viable and mean the same thing, even though they might seem different at first. In other languages, french for example, only example B) would be correct, but in English, both work fine.

Also, you can further shorten both sentences by just saying “Most people in Tokyo wear masks/a mask.”

英語は簡単だよね？(冗談)
