The revisions of territory and urban planning system were performed in Korea after 1999, and land use plan system was unifide. In addition, City-Region Planning was foundedfor the same period, and regional adjustment came to be planned. This study is aimed for the presentations of a suggestion to Japan and an ideal method of regional adjustment by introducing an adjustment of greenbelt in City-Region Planning of Korea. A greenbelt contributed to urban management and protection of environment. However an infringement of a property right and other problems by greenbelt were pointed out, and necessity of adjustment was on the rise. And the Korea government chose City-Region Planning as greenbelt adjustment method. The adjustment resulted in an objective agreement by using a scientific method. Such a Korean experience may be useful for Japanese regional adjustment.
