This paper analyses the identifiableness of cityscape, to research how nightscapes differ from daytime landscapes and to find how we can make identifiable nightscapes. The method is a questionnaire survey which consists of the three steps below: (1) Pick up the 16 spots in the central area of Niigata city and take pictures of them. (2) Ask the respondents where the spot is and by what it is judged. (3) Classify the spots through clustering analysis by using the right answer rations and test the differences between the noted points of daytime landscapes and nightscapes. The chief findings are as follows: (1) The clustering method above proves to be useful to understand the feature of each spot. (2) The right answer ratio decreases at night where the distant landmarks are hidden in the dark. (3) To identify the spots, facades of near buildings, near sign boards, near neon signs and facades of distant buildings are commonly noted in daytime and at night. (4) Nearer figures tend to be noted in identifying the nightscapes. (5) The "literal informations" are noted more at night than in daytime. The "shape informations" are re-verse. Therefore, we conclude that lightening the shape of well-known landmarks is very important to make easily-identifiable nightscapes.
