@wolfie @hakui There might be stores who will outright force you to wear one, in that case record the conflict and bring it to a koban (police box), because forcing people to wear a face diaper or get denied service is illegal according both Japanese law and Japanese constitution.

I don't believe in these artificial "laws", and I know this won't have much effect if at all, but with some luck it does bring some awareness to the public, and perhaps this will finally wake a bit more sheeple up.

The reason why I didn't do so is because it very rarely happens to me, and if it happens, I don't have my phone with me, because that thing is always at home anyway.
