Abstract
J-system is a general-purpose information provision system geared to information service providers (including the print and broadcast media). The system processes the information collected by JARTIC from prefectural police departments and transport administrators and makes it available via Internet, mobile phone, television and other media. In 1986, the authors started developing an internal system. Upon its completion in April 1999, they launched development of J-system. They completed this system in December 1999, toward providing information more quickly and accurately to anyone, anytime, anywhere.
