Anecdotal evidence. Why does Japan do better than US? Considering it is more population dense, has more older people, and a frequent train goers. Japan does not do better compared to other Asian countries like South Korea or Taiwan, because the other Asian countries enact more measurements than Japan other than just masks. Japan pretty much doesn't really care that much about Covid compared to other Asian countries but they always wear masks. My wife is going to office everyday (Tokyo), she is also going to a wedding party tonight, and also next week. Life is really going pretty much normal right there.
