We were interested in the forms which appear repeatedly in village non-systematically. We paid attention to vertical visual division (view distance) of road in old village. The purpose of this paper is to make clear the characteristic of this view distance. We selected and surveyed 49 villages in Ibaraki and Yamanashi Prefecture. As a result, view distance is given in log-normal distribution (median: about50m, 95%tile: about 100m). This characteristic isn't related to the topography and location of village. And, this characteristic doesn't depend on the road width and form of street network. It is found that the view distance distribution owes to the factors as follow:“Microtopograpy factor”, “Pedestrian goal factor”, “Building plot factor” and “Planning unit factor”.
