Constituent members of the space for Japanese traditional architecture were classified into four or five clusters. Perceptive characteristics of the members are understandable by considering the cluster to which they belong. Roofs are characterized by their form such as layout, shape and texture. Walls are characterized by their surface nature such as pattern, color and luster. Ceilings and bracketings are characterized both by form and by nature. The correlation of these members and the image of the space for Japanese traditional architecture will be described in the following paper.
