The information and communications services network and environment are bringing about changes in industry structure and every aspect of people’s lives, as seen in the enhancement of the broadband communications environment, including FTTH and LTE, the rapid proliferation of smartphones, tablets and other devices, and the growing use of social media and cloud computing. The use of ICT by a number of service providers in the information and communications services market is becoming more widespread, as is the use of information and communications to generate innovative new services that will contribute to greater economic growth and the vitalization of local economies driven by the Tokyo Olympics and Paralympics, and also to work to resolve Japan’s anticipated social issues, such as the low birthrate and aging population. At the same time, security threats have emerged, as can be seen in the increase in incidents of cyber-terrorism, and the role of information and communications services in achieving the secure and reliable operation of social systems and enriching people’s lifestyles is becoming increasingly important.

To help ensure that universal services are maintained amid this evolving information and communications environment, NTT intends to provide all necessary advice, coordination, and other assistance to Nippon Telegraph and Telephone East Corporation and Nippon Telegraph and Telephone West Corporation (the “regional companies”). NTT will also endeavor to promote research and development in information communications technology, which serves as a foundation for telecommunications.

In addition, NTT announced the “Hikari Collaboration Model” in May 2014 pursuant to the announcement of NTT Group’s “Towards the Next Stage” strategy in November 2012 aimed at promoting initiatives to create a variety of services and business opportunities. Each NTT Group company, including the regional companies, will continue to pursue a B2B2C model by working to reform its own business model and collaborating with a variety of service providers as a Value Partner that customers continue to select. As NTT undertakes these initiatives, it intends to continue to ensure fair competitive conditions under the existing legal framework, as it has done thus far. In addition to these measures, NTT will also work to increase corporate value by actively expanding its global business and engaging in management directed at the development of NTT Group as a whole.

Based on these fundamental concepts, in the management of its business operations for the fiscal year ending March 31, 2016, NTT will aim to grow its businesses by actively developing global business and strengthening the profitability of its network services, while also striving for business growth by supporting the creation of new services through the Hikari Collaboration Model. NTT will seek to ensure the stable development of its operations in the future, and to return the fruits of these efforts to customers, shareholders and the community at large by building an advanced broadband network, creating a variety of services, and engaging in research and development activities that will strengthen open innovation and generate the technology and human capital to support a new business model.

1

Based on the concepts outlined above, pursuant to the business operation plan for the fiscal year ending March 31, 2016, NTT expects to manage its business by prioritizing the following activities, and doing so in a flexible manner so as to respond to changes in the business environment.

1. Advice, coordination, and other assistance

NTT will aim to exercise appropriate shareholder rights and provide all necessary advice, coordination and other assistance to its regional companies to ensure the maintenance of high-quality and stable universal services. Such assistance will include planning and coordination relating to the quality and upgrading of telecommunications networks, deployment of control and coordination capabilities in the event of natural disasters and other emergencies, efficient financing, and formulation of policies for material procurement.

NTT will support the efforts of each NTT Group company, including the regional companies, to streamline their business operations and expand their business opportunities, and will assist with the development of human capital that will form the core of NTT Group as well as compliance with applicable regulations.

2. Promotion of basic research and development

NTT Group will work to harmonize network platform technologies, technologies that provide a basis for new services and applications, as well as general advanced and basic technologies, while at the same time accelerating innovation and collaboration. Through these undertakings, NTT Group will focus its efforts on higher value-added research and development, as well as continue to be actively involved in expansion and standardization activities, such as participating in research and development activities in collaboration with other research and development institutions and in technology exchanges both in Japan and abroad.

NTT will seek to further increase research efficiency and ensure the continuous execution of basic research and development efforts through revenues generated from the use of such efforts, and the bearing of related expenses on an ongoing basis, by the regional companies and other NTT Group companies.

2

Specifically, NTT will give priority to the following areas of NTT’s research and development activities:

(1) Infrastructure-related research and development

In order to develop an information network infrastructure to “connect” everything under the concepts of “smart,” “simple” and “sustainable,” NTT Group will undertake research and development concerning future network technology. Specifically, NTT will pursue research and development aimed at the realization of a network co-created with service providers on network simplification technology using NFV (Network Function Virtualization) and other software, and “service chaining” technology that enables the selective use of multiple network services by users. NTT will also pursue research and development that supports disaster-resistant networks as well as research and development directed toward realizing common network platforms usable in different services and fields, such as strengthening the relationship between fixed-line and mobile communications and further convergence of telephone and IP networks.

(2) User-related research and development

With a view toward creating advanced services that enrich the lives of and provide comfort to customers, NTT Group plans to undertake research and development in technologies that integrate telecommunications and computer technology, such as media processing, personalization, cloud services and security. Specifically, NTT Group will promote research and development in the following technologies: next-generation video codec technology on which development is being carried out for use in 4K/8K video, data analysis technology to provide services in accordance with the user’s circumstances and intentions, cloud platform technology that enables the efficient use of networks in data centers and flexible links between on-premise and public clouds, and security-related technology, such as SIEM (Security Information and Event Management) platforms, to counteract cyberattacks.

NTT also intends to engage in activities that provide support to other companies, universities and other institutions with the goal of raising the cybersecurity skill level in all industries while simultaneously developing security experts within NTT Group.

3

(3) Research and development in basic technologies

NTT is committed to contributing to the innovative development of information and telecommunications in Japan to ensure a leading position in technology research that will support the future of telecommunications. To fulfill these commitments, NTT will undertake research and development activities in basic technologies. Specifically, this will include research in areas such as: wearable biosensing technology such as “hitoe,” a performance material capable of measuring biometric information, and optical devices and integrated nanophotonics technologies that enable ultra-compact 100Gbps digital coherent transceivers. NTT will also pursue research on innovative principles and new concepts, including quantum computer-related technology that exceeds current information processing capabilities; a broad range of cutting-edge materials, including nitride semiconductors and grapheme, and nanobiology; and a scientific analysis of the human sensory, physical and emotional mechanisms related to communications.

Information and communications services have become an essential part of the infrastructure of socio-economic activity. These services are expected to make significant contributions to increasing the convenience of people’s daily lives and the vitalization of local economies, while also improving corporate efficiency, creating new businesses and enhancing industry-wide international competitiveness.

The information and communications market is growing due to an increasing shift to broadband services and globalization. The market is undergoing structural changes beyond the existing framework, including fixed-mobile convergence, cloud computing and smart TV development, penetration of high-speed wireless and Wi-Fi compatible devices, such as smartphones and tablet devices, and widespread use of applications that enable free phone calls and messaging. Regional telecommunications markets are also changing dramatically, with intensifying competition in broadband access facilities and services centered around the shift to fiber-optic access, and increasing offloading needs due to the expansion of the volume of data communications. New services that leverage a variety of wireless devices are also expanding, which in turn leads to diversification in the way that customers are using these devices.

Amid such a difficult and volatile business environment, as a carrier with an important leadership role in the information and communications industry, NTT East will aim to continue to provide high-quality, stable universal services, work to develop a disaster-resistant information and communications network and to promptly restore services in times of large-scale natural disasters and other calamities in order to ensure their reliability as part of the social infrastructure, and respond to network migration appropriately. NTT East will do this while striving to ensure that it strictly abides by the requirements of fair competition and seeking to secure a stable and solid foundation for its business, as well as complying with applicable regulations.

Furthermore, NTT East will endeavor to contribute to the further enrichment and sustained development of society by enhancing the broadband and ubiquitous network environment and further expanding fiber-optic access. NTT East intends to achieve these objectives by offering services and products that leverage the advantages of the next-generation network (“NGN”), as well as offering customer-friendly pricing options with long-term appeal, and by using information communication technology (“ICT”) to confront the various economic and social issues facing Japan, such as the low birthrate and aging population, and achieving a low-carbon society.

- 1 -

With regard to the management of its business operations for the fiscal year ending March 31, 2016, amid the continuing economic recovery resulting from a positive economic growth cycle, NTT East plans to continue expanding and promoting the use of fiber-optic access, and aims to achieve the upgrade and expansion of its broadband network environment through the NGN on the basis described above. These objectives will be achieved through the creation of new uses for ICT that are closely connected to daily domestic life and community activities, the enhancement of the ICT environment through, among other things, the use of Wi-Fi, and the development and provision of services for business users.

NTT East plans to offer an even wider range of services for IP telephony and video services, including maintenance and support for network infrastructure. As an “accessible, full-service ICT company,” NTT East at the same time aims to develop and provide a variety of high value-added and user-friendly services designed to provide customers and local communities with a sense of security, safety and convenience, including new services created through further collaboration with companies in diverse industries, and to further improve customer services. In addition, NTT East will provide service providers in a wide range of fields with fair and equal services on the basis of its world-class network through the Hikari Collaboration Model, as well as support a variety of value creation opportunities.

At the same time, NTT East will also take steps to ensure steady business growth into the future by further increasing operating efficiency and reinforcing its management base. NTT East will strive to return the results of these measures to customers, the local community and, through its holding company, to its shareholders.

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. Accordingly, the government and the private sector are working in partnership to achieve the development of a ubiquitous broadband network society in which there is an advanced level of utilization of information communication technology (“ICT”). 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 smartphones, tablets and social media. The market is catering to increasingly sophisticated and diversified needs by, among other things, 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 optical, IP-based networks and enhance the fiber-optic access network that is the backbone of broadband services, 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 rigorously ensuring fair terms of competition within the current legal framework as well as encouraging thorough compliance, NTT West will also aim to realize a broadband and ubiquitous 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. At the same time, NTT West will endeavor to contribute to the development of an information distribution society and the creation of a new lifestyle by expanding the use of fiber-optic services, including the provision of various lower-rate plans that match each customer’s patterns of usage, and a variety of other services.

These are the basic concepts that underlie the business plan for the fiscal year ending March 31, 2016. 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 creating new services through the fair and equal provision of the Hikari Collaboration Model to, and promotion of collaborations with, a variety of service providers. 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, improving both the range and quality of services 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 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. Amid a difficult business environment, NTT West will strive to continue to improve the efficiency of its operations so as to maintain profitability.

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.
