I. Progress in Information and Communication Revolutions Communication technology and changes in the system of electrical communications have promoted the demand for new types of communications such as data and images in Japan. At present, the information and communication network in Japan is rapidly developing. The technologies such as electronic exchange, optical communication and satellite communication are developing rapidly. The miniaturization, high-functionalization and storage and processing of high-capacity information have all reached the practical stage. In 1985, Japan implemented the privatization of telecom companies. At present, there are 16 companies that own communication networks in Japan’s telecommunications companies and 350 or more value-added communications businesses are leased to other networks.
