It's not untrue. I've lived in Japan 14 years. I have pictures from late March of people out and about without masks. Sure, it was not uncommon to see a few people wearing masks in Asia (and Japan) before the epidemic but it was not remotely everyone at any time until the lockdown in April. Usually an average train of 200 people might have 10-20 people with masks on (before the lockdown) Here's pictures March 24th (and one in late Jan which shows zero masks) https://photos.app.goo.gl/aUWB5YB6vBnjZk8j6 https://photos.app.goo.gl/aUWB5YB6vBnjZk8j6 So no, it's not because Japanese wear masks. I'm not saying that doesn't help but it's clearly not enough given how crowded the trains are and how late it was until everyone started wearing them
