Hokkaido is located on the northern tip of Japan whose natural condition is severe because of snow coverage and cold winter, wide peaty and soft ground. In order to overcome many engineering problems, Hokkaido Regional Development Bureau has addressed engineering development and promoted projects for regional development with these engineering.
Civil Engineering Research Institute for Cold Region (Incorporated Administrative Agency Public Works Research Institute) supports Hokkaido development administration through investigation, examination, research and development of civil engineering technologies.
