Abstract
The purpose of this study is to discuss the ways of natural disaster risk reduction based on the traditional local knowledge. In this study, we focused on the location of 398 shrines in Wakayama Prefecture in order to uncover the profile of space accumulated in the community. More specifically, a survey about the location of shrines and the risk potential of tsunami, floods and sediment disaster showed that many shrines escaped disaster hazard area. And by the investigation of the history and origin of each shrines, we have extracted that majority of Engi-Shikinaisha（shrines listed in Engishiki laws）, Kumano shrines, Isotakeru shrines and Ohji shrines are located at out of the disaster hazard area.
