March 1, 2018

Nippon Telegraph and Telephone West Corporation (“NTT West”) today submitted its business operation plan for the fiscal year ending March 31, 2019 to the Minister for Internal Affairs and Communications for approval.

Information and communications services are expected to make significant contributions to the invigoration and increased efficiency of social and economic activities, improvements in lifestyle convenience and the vitalization of local economies through the formation of a new ICT society from the development of AI, Big Data and IoT. The government and the private sector are working in partnership to achieve these goals.

Moreover, the information and telecommunications market is undergoing a structural change as a result of the shift to broadband and globalization, as well as the spread of smart devices and social media. The market is catering to increasingly sophisticated and diversified needs and patterns of usage by, among other things, utilizing Big Data and IoT, as well as expanding platform services and cloud services. Regional telecommunications markets are also undergoing significant changes, such as the convergence of fixed and mobile services, and of telecommunications and broadcasting, and the introduction of new services as a result of the use of a diverse range of wireless devices. This is due in part to an increase in competition not only between the providers of fiber-optic access services and cable television-based broadband services but also between the various services made available by faster mobile connections.

Within this challenging and dramatically changing business environment, NTT West is striving to promote the smooth migration to IP-based networks and enhance the fiber-optic access network that is the backbone of ICT, as well as continue to provide high-quality, stable universal services. NTT West also aims to contribute to the development of fair telecommunications markets and promote applied research and development to ensure the reliability and public utilization of telecommunications services.

While strictly adhering to fair terms of competition within the current legal framework and encouraging thorough compliance, NTT West will also aim to realize a broadband network environment that will enable customers to connect “anytime, anywhere and with anyone or anything” and “in comfort, safety and with peace of mind.” NTT West will achieve this by offering an open next-generation network (“NGN”) that utilizes the unique characteristics of fiber optics and by expanding its Wi-Fi platform, among other initiatives. At the same time, NTT West will endeavor to utilize ICT to contribute to the realization of a convenient and prosperous society through the creation of a new lifestyle by expanding the use of fiber-optic services and through developing solutions for issues facing society, including the provision of “various services that match each customer's patterns of usage.”

These are the basic concepts that underlie the business plan for the fiscal year ending March 31, 2019. In its broadband services, NTT West expects to provide a more comfortable, safer and more secure NGN. In addition, NTT West will strive to provide customers with greater convenience by developing Hikari Denwa services that make use of fiber-optic access lines, video distribution services, and services for corporate users, as well as by providing the Hikari Collaboration Model to a wide-range of service providers in an appropriate and fair manner, and promoting collaborations in order to create new services. NTT West also plans to maintain its community-oriented sales activities in order to respond to customers' opinions and requests in an appropriate and timely manner, develop ICT solutions aimed at resolving issues facing society, improving the quality of services for customers and contributing to the development of local communities.

In conjunction with this, and in recognition of its responsibilities as an operator of social infrastructure, NTT West will aim to contribute to the creation of a safe and secure society by seeking to ensure the stable provision of its broadband access, Hikari Denwa and other services, attempting to prevent equipment failures, strengthening facilities countermeasures in preparation for possible large-scale disasters, responding vigorously to restore service and providing victims and affected individuals with various means of communication in times of disaster, and bringing all of its group resources to bear on activities and services that will earn the continued trust of its customers. NTT West will strive to continue to improve the efficiency of its operations and to achieve a stable and strong management base.

NTT West will work to lay the foundations for the stable development of its business into the future by proactively working to facilitate connectivity and ensure the openness of its networks, actively promoting human resource development, expanding into new business areas in coordination with its group companies, and making a positive contribution to reducing its burden on the environment. As these policies and programs bear fruit, NTT West will endeavor to share the benefits with its customers, local communities and, through its holding company, its shareholders.
