It is thought that among geographical regions there exist many geographical orientations…… industry, trade and commerce, matrimony, emigration, etc. In a geographical community also exist various psychological orientations. This monograph attempts to throw light on the regional characters based on subjective orientations in these human communications inherent in geographical regions, which have far been neglected. Viewed from this point, it has been made clear that the small island Toshima is hindered with a psychological structure more stagnant than one observable in Japan proper, although it should make its islanders' living by much shrewd commercial productions…… of camellia oil, ceylon moss, spring lobster A and the like……with Ôshima Island on the same archipelago and Tokyo. It is important, therefore, for future development of the island that it be given, from a macroscopic angle, better social, economic objective conditions and, from a microscopic angle, a motivation that will revise the above-mentioned insularity inside. The present writer is of an opinion that by generalizing this idea we will be able to overcome the “relativisme psychologique” of J. Brunhes once criticized by L. Febvre and then, from the viewpoint of Human Ecology, to confer a theoretical unity to the diversity of directions the movement of its habitat takes.
