In 1984, many people had arguments about privacy in Japan, stimulated by "NINETEEN EIGHTY-FOUR", written by George Orwell. At that time I noticed that the word "puraibashii" — which means "privacy" in Japanese — was used in the flyers advertising new residences enclosed with newspapers. I surveyed the frequency in use of that word and how it was used for one month from May to June in 1984. The word "puraibashii" was of great importance for the advertisements of new residences. Twelve years have passed, since the first survey. I again made a survey of that word by the same method this spring, in order to examine the change over ten years. In 1984, the word was used in twelve flyers — ten for condominiums and two for houses. In 1996 it was used in twenty-three of forty-three flyers for condominiums and in one of thirty-one flyers for houses. I present these data in Appendix 1 and 2. As the Japanese didn't have a word which corresponds exactly to "privacy", a new word "puraibashii" was created. However, I think that the Japanese don't desire simply the defense of privacy but the existence of "Ma", unconsciously by using the word "puraibasii". Here, "Ma" means the space between one residence and another. This space isn't empty. Traditionally it has a meaning in Japan. This "Ma" is very important in interpersonal communication, and especially in international communication, though it, has been gradually lost over the last fifty years. I term communication including "Ma" Communication of Ma".
