It is important to analyze streetscape because the street becomes the place where the pedestrian experience townscape. In this study, we investigated how to see landscape resources on typical streets by focusing on sequential landscape in the old castle town in Sanda City, Hyogo. We took pictures of the streetscape every 15m, and grasped having landscape resources or not in the photograph. Based on this result, we extracted typical scene landscapes on the streets, and specified 13 important areas where landscape resources are seen characteristically by analysis of sequentiality of scene landscape and road shape. In important areas, road shape such as a curve or a slope affected how to see landscape resources, and created characteristic sequential landscape. It is suggested that extracting of important areas enables showing the place where should be worked on landscape planning as priority, and the basis of guidelines for landscape planning of old castle town.
