Well, I want to tell you dear foreign readers.. information officers on business, in private out of curiosity, whoever you are.. Please don't send me messages in English, or any other foreign languages. Messages (or subjects written) in Chinese, English and Russian languages will be automatically screened out, and anyway I don't read and just throw them away.. 
If it's in French, I may react "Ha!", but no English please. Just only subject is fine, write in Japanese please. You can make the contents too much complicated, but not the subject. I won't read it if the subject is in English. (I am talking about you, a "government official" of that country!!)
