Delineation of the Spatial Spheres Outdoors Indicated by the Japanese Verbs, “Hairu” and “Deru”

The purpose of this study is to clarify whether and how the spatial sphere that is shared by majority of people is identified. First, the experiment was conducted to draw spatial spheres using the Japanese verbs “Hairu” and “Deru” outdoors. Second, using the originally devised measurement of similarities, and the cluster analysis, the spatial spheres drawn by the subjects were divided into several groups, and the average shapes of the grouped spatial spheres were delineated. Finally, throughout the comparison between the characteristics of the shapes of the spheres and the spatial environment of the experimentation site, it was confirmed that it is fair to say that the spatial spheres that are shared by majority of people exist, and the spheres appear under the influence of spatial characteristics of the surrounding environment.
