Abstract
The purpose of this research was to explore the changing appearance in day and night scenes in Sapporo and Otaru area. The aspect of visual phenomena like color and light can be understood by analying the appearance of cityscape. By grasping the changing appearance of color in snowing regions, it was cleared that winter season creates different appearance particularly due to the role of the white covered. Sapporo area shows mainly straight extent scenes in day and night, but residential area from Susukino westward was turned as a dark scene without distinctive hierarchies in night. Otaru area was divided into two scenes, straight and flat extent scenes in day and night. It was showed mainly white scenes in day and black scenes in night.
