Nationwide database for well and groundwater information is required from the view point of emergency control of calamity disasters and environmental protections. The Hydrogeology Section of the Geological Survey of Japan has completed a nationwide well and hydrology database (Marui et al., 1996). This paper outlines the features of the database and its accompanying software, called Idojibiki in Japanese (for Windows 95/98/NT), which allows search and display of this database on a personal computer.
