Digital divide, also known as information disparity, refers to the various gaps brought on by disparity in the ability to collect in-formation using information terminals or the opportunities to use information technology. While the development of advanced nations is accelerating by information technology, some developing nations are having difficulty even building their infrastructures, eliciting a fear that the gaps among nations might widen. Japan has a “regional issue,” where information is inaccessible from remote islands and deep in the mountains, as well as a “generational issue,” where the elderly cannot take advantage of the information. Meanwhile, corporations have started global expansions, highlighting issues in culture and language. These circumstances are drawing high ex-pectations for research and development in the communication field.
