This study analyzed the transition of discussions, current state and tasks of buffer zone for world cultural heritage, based on data and minutes (1992-2019) of the World Heritage Committee. As a result, 1) The purpose for regulating the visual influence of the development around the heritages was strengthened in the buffer zone originated from the protection of surrounding environment under the Operational Guidelines. After the revision of Operational Guidelines in 2005, the establishment of buffer zone actually became mandatory, and its necessity was recognized at relevant international conferences, so the buffer zone was established in many cultural heritages. 2) Even though the establishment of buffer zone is currently the most important task for both world heritages in danger and the general world heritages, the weight of deliberation on management & regulation after establishment is increasing. On the other hand, the coordination and cooperation with interested parties and residents are barely mentioned. 3) This study suggests discussing the measures for balancing the future development regulations, protection of surrounding environment, and coordination & cooperation, in Asia with high establishment rate of buffer zone.
