The purpose of this paper is to clear the assumptions for establishing a sustainable cultural heritage management in Taketomi Island by bringing out the model of relationship between cultural heritage and local community using tourism. As a result, we found the factor of the unbridgeable gulf of the cultural heritage and life by understanding the change in "Work" and "Role". We propose four policies for cultural heritage management, to set upon conservation of cultural heritage in Taketomi Island, to manage the informations about cultural heritage, to operate the system for taking advantage of cultural heritage, and to improve an environment for settlement, and clear the concept and the role of NPO managing cultural heritage.
