This chapter will give an overview of the industrial structure and regulatory scheme of the telecommunications industry in Japan. While there is a huge array of companies populating the telecommunications industry, large companies such as NTT and KDDI are few. Technological progress in this industry is rapid, compared with advances in other public utility industries. Since the Nippon Telegraph and Telephone public corporation was privatized in 1985, regulatory reforms have been enacted with dramatic results. Among the several privatizations of formerly state-owned organizations, that of the telecommunications industry has experienced the most deregulation, with telecommunications facing the most severe intra-industry competition of all the formerly public entities. After the introduction, in the second section, the market structure of the telecommunications industry in Japan is explained, with information regarding market size, the number of telephone customers, and the major telecommunications companies.
