We love finding signs in Japan, made by Japanese, written in English, by people whose native language is not English. I have discovered the same kind of thing in Afghanistan but with German, French, Italian, Dari and others writing the signs. Now, I am willing to bet that what this sign is prohibiting is actually not a real problem. However, if it is a real problem, I do not want to meet the individuals who are struggling with this as an issue in their lives. I am thinking, though, if you were really wanting to discourage people from smoking, allowing smoking only where it is prohibited by the sign, would significantly decrease all but the truly dedicated smoker's desire to smoke at all.
