| This abstract describes the development of an Internet web service that provides data on boreholes near the surface. A beta version of the website (www.kunijiban.pwri.go.jp), which is called KuniJiban, was started by the Public Works Research Institute (PWRI) at the end of March in 2008, and is also managed by both the Ministry of Land, Infrastructure, Transport and Tourism (MLIT) and Port and Airport Research Institute (PARI) under the MLIT. The website offers free access to 270,000 borehole data of the MLIT. |
