Geographical Analyses on Distribution of Archeological Sites of Village and Hill-fort

This paper treats the relation between two kinds of important sites of ancient Japan, in the Late Yayoi period (100-300AD), by using a geographical information system. One is a group of village sites which existed through the period. Another is a group of hill-fort sites with beacon facilities. The authors have already shown a network of interrelation between village sites, which showed a sort of connection between sites from the viewpoint of cost of movement. On the other hand, ancient communication networks have been given between hill-fort sites based on visibility between them. Integrating these independent researches, this paper presents an analysis on the geographical distribution of both types of sites. We take the sample sites within a special region for simulation, which are distributed along Yodo River in Osaka and Kyoto Prefectures. We could obtain good understanding of mutual relations between villages and hill-forts. 1
