The purposes of this study are to clarify the subjects of the urbanization area of the two different coal mining regions of Chikuho and Sorachi through the evaluation and comparison of the revitalization policies after the coal mining industrial age, and to propose the development method of the public housing sites in these areas. As a result, the differences of the urban environments between both regions were pointed out by figuring out the difference of revitalization policies and financial conditions. Based on the analysis, we suggested the schemes for each of regions; in Chikuho, the public housing sites which are located in convenient urban are to be rebuild to connect with other urban policies like welfare or commercial. In Sorachi, low density public housing sites are to be unified or cleared and to make the efficient urban areas by relocating these areas in linear network.
