NTT Submits Business Operation Plan for Fiscal Year Ending March 31, 1997 to Minister of Posts and Telecommunications for Approval

Nippon Telegraph and Telephone Corporation (NTT) announced today that it has submitted its business operation plan for fiscal year ending March 31, 1997, to the Minister of Posts and Telecommunications for approval.

Under this plan, NTT will improve services by surveying customer needs and advance its stable management bases by making efforts to reduce costs and increase sales and work to establish smooth interconnection discussions and open access networks. NTT will strengthen its R&D and disaster prevention measures. It will also promote staff member training and new business development for the future growth of the company and contribute to its customers, stockholders and to society.

The telecommunications industry is expected to actively contribute to the development and efficiency of social and economic activities. Its market is rapidly developing to meet more sophisticated, diverse, and global customer needs and is taking firm steps in the world trend toward the multimedia era through remarkable technological developments. Intensifying competition, especially in the long-distance telecommunications market, is going to enter a new era, shifting from mere price competition to real service competition. Also, the mobile telephone market is expanding rapidly and competition in the local communications markets are appearing as new trends.
In these circumstances, NTT continues to provide both stable and high-quality universal services and innovative new services for a wide range of corporate and individual activities; to promote concrete activities toward realizing the multimedia era; to contribute to the achievement of telecommunications markets with fair competition; to develop infrastructure, such as optical access network for the 21st century; and to minimize the information gaps among areas. NTT is also working for the early provision of new services, nationwide; conducting greater R&D; maintaining its public-service functions; participating in domestic telecommunications businesses in foreign countries; responding to customer expectations; and contributing to society. NTT will achieve these important missions by stabilizing and ensuring its management bases. Under NTT's operation plan for fiscal year ending March 31, 1997, the company will implement a flexible management in response to the changing managerial environment, putting emphasis on the following items:
