Information technology (IT) is one of the transformative forces in the world today. As an engine of innovation and growth, it has transformed the economic structure in a wide range of areas, and it has reorganized social activities in ways not yet completely understood. IT also raises critical policy issues, particularly around the role of information privacy, security, and networks. Japan’s IT sector has experienced major shifts in its regulatory and industry structure as it developed cutting-edge services but became isolated from global markets. It offers rich areas for political economy research that can provide implications for developments elsewhere. Related JSP activities include speaker series, workshops, and publications.
