Abstract
This is a report based on several results of the analyses of the relation between the urban structure and Kôgai related to the processing industry of marine products, in four cities (Hakodate, Otaru, Rumoi and Wakkanai) which are situated on the western coast of Hokkaido.
There are nasty smell and water pollution in urban Kôgai which is caused by the above industry. These nasty smell have much influence over the relatively limited range of urban areas in Hakodate and Otaru, while they tend to spread all over the urban areas in Rumoi and Wakkanai. As to water pollution on the other hand, the conditions are diversified among these cities.
From these analyses, the writer revealed some regional differences between Hakodate, Otaru and Rumoi, Wakkanai in the consciousness of the inhabitants and the counter-measures for these Kôgai.
