<p>In order to discuss the importance of visual landscape, especially visual connection between inhabitants and their surrounding natural and social environments in everyday lives, visibilities to sea from traditional settlements in coastal zone were surveyed. As a case study along San-riku coastal area, where is historically frequent-damaged area by tsunami in north-east Japan, visibility frequencies to sea from settlements (n=584) were examined exhaustively. Cumulative viewshed analysis on DEM by GIS (ArcMap) was used for the calculation of visibility frequencies. The result shows a tendency that approximately 30 % or more of entire settlements dispersed along the coastal area, regardless of fishery or non-fishery (mostly agricultural) settlement, have relatively higher frequencies of visibility to sea than their surrounding land. It is believed that people's experiences in everyday life is one of the basic reasons for their continued occupation, and the idea of visual connection using the method of visibility frequency analysis is expected to be an important contribution for enhancing the ways of evaluation of cultural landscapes.</p>
