Abstract
The author reviewed the usage of the ward “Karesansui” in pre-modern and modern era, which is a style of Japanese gardens as we think today. Through the study it was made clear that the ward “Hiraniwa”, one of Japanese garden style defined in pre-modern era, has not been used as a style of Japanese garden. On the other hand the ward “Karesansui” has been used more in the changing situation of the idea of Japanese garden style. Also the author pointed out that the design vocabulary of Karesansui has been getting more popular in the modanists' design and their articles after Warld War II, and reached to an important design concept of modern landscape design.
