KuniJiban

"KuniJiban", a search site for national geotechnical information, is jointly operated by the Ministry of Land, Infrastructure, Transport and Tourism, the Public Works Research Institute and the Port and Airport Research Institute, and is maintained by the Public Works Research Institute. On this website, you can search and view the boring logs and soil test results obtained by geological and soil surveys for road and river projects of the Ministry of Land, Infrastructure, Transport and Tourism. Through providing such geotechnical information widely to the general public, this website is expected to support environmental conservation and disaster measures, in addition to making social infrastructure development more efficient between the national government and municipalities as well as between municipalities. As of January 9, 2009, this site provides approximately 34,000 boring logs and tables of soil test results within the jurisdictions of the Hokkaido Regional Development Bureau, the Tohoku Regional Development Bureau, the Kanto Regional Development Bureau, the Hokuriku Regional Development Bureau, the Chubu Regional Development Bureau, the Kinki Regional Development Bureau, the Chugoku Regional Development Bureau, the Shikoku Regional Development Bureau and the Kyushu Regional Development Bureau as a trial. This website is published without charge using the Cyber-Japan Web System to reflect the provisions on geotechnical information in policies of the Basic Plan for the Advancement of Utilizing Geospatial Information, which is based on the Basic Act on the Advancement of Utilizing Geospatial Information, and the "Ministry of Land, Infrastructure, Transport and Tourism CALS/EC Action Program 2005". The launch of this website was also in response to the recommendation titled "For Advanced Utilization of Geotechnical Information" summarized at the end of fiscal year 2007 by the "Committee on the Accumulation and Utilization of Geotechnical Information". Since April 2008, the basal geographical information published by the Geographical Survey Institute has become available for use as the background in part. Moreover, the achievements gained by the "Development of Integrated Geophysical and Geological Information Database", an R&D Program for Resolving Critical Issues supported by the Science and Technology Promotion and Coordination Fund, are utilized on this website.
