"This paper is a study of the emotional effects of shadows, found in both traditional and urban districts in Japan. In our modern, urban environments, beautiful shadows can be found in only a few townscapes. In this study, we attempt to understand what the elements of attractive or inhospitable shadows are and how they affect the ordinary person. Some examples of increasingly rare and beautiful shadows can be found in the towns built around the shrines and temples in Japan. The atmosphere is based on their exceptional compositions of architecture and their external approach to space. In these places, beautiful shadows are formed by unseen patterns that take into account the cultural climate. Some examples are the gentle light created by the illumination of paper, and other amiable shadows produced by organic substances such as trees and wooden houses. Shadows and light can deepen a space and transform the atmosphere of a place. Faint and dusky shadows create a realm of mystery and remind us of the ties we have to the past. These shadows are very important in creating traditional Japanese spaces. It is felt that shadows sould be re-evaluated for the possibility they offer in shaping the metamorphosis of our increasingly modern townscapes to give them a more human, more life-enhancing quality. As modern materials and architecture are turned into "modern" buildings, towns, and cities, the metamorphosis of the townscapes we inhabit continues without letup. Even though new materials are used, can we nonetheless recapture a townscape with the same kinds of beautiful shadows as are found in traditional settings? Pictures of shadows can be used as a representative models distilled from the essence of the townscape. Modern and historic townscapes might be linked together by means of their common media, that is, the shadows. If so, the essence of the culture can continue on into the future. The question to be considered is whether or not the traditional essences can be woven into the ongoing metamorphosis of the images found in our cities and towns. In this paper, some characteristic of shadows were identified by performing psychological experiments. The shadows used in our research came from the traditional districts in and around the temples of Kyoto and from the cityscape of the contemporary urban districts around Kyoto and Osaka. These shadows are classified by image analysis and their features are compared and summarized."
