Submission for Approval of Business Operation Plan for the Fiscal Year Ending March 31, 2018

Information and communications services have started to realize the creation and provision of new value in a wide range of fields including improvements in the convenience of people's lives and greater efficiency in each industry. It is now possible to store and analyze various types of data due to the enhancement of the broadband communications environment, including FTTH and LTE, the proliferation and penetration of smartphones, tablets and other devices, the growing use of cloud computing and advances in technologies such as AI, Big Data, and IoT.

The use of ICT by a number of service providers in the information and communications services market is becoming more widespread, and business partnerships that go beyond the boundaries of industry sectors and business types have started to generate an increasing variety of innovative new services in order to contribute to greater economic growth and the vitalization of local economies driven by the Olympic and Paralympic Games Tokyo 2020, and also to work to resolve Japan's anticipated social issues, such as the low birthrate and aging population.

At the same time, the strengthening of countermeasures against increasingly sophisticated and complex security threats and for disaster prevention demonstrate that 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 Group's Medium-Term Management Strategy entitled, "Towards the Next Stage," announced in November 2012 was revised in May 2015. Each NTT Group company, including the regional companies, will continue to pursue a B2B2X model by working to reform its own business model with the aim of becoming a "Value Partner" that customers continue to select and collaborating with a variety of service providers.

As NTT undertakes these initiatives, it intends to continue to ensure fair competitive conditions under the existing legal framework.

In addition to these measures, NTT will also work to increase corporate value by actively expanding its global business, strengthening the profitability of its network services, and to engage 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, 2018, NTT will aim to continuously grow its businesses by actively developing global business and strengthening the profitability of its network services, while also striving to accelerate the shift to a B2B2X model for business growth by supporting the creation of new services and business opportunities through collaborations with business partners in a variety of industrial fields.

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 society by providing an advanced broadband network, creating a variety of services, and engaging in research and development activities that will produce the technology and human capital to support a new business model by sustaining and strengthening open innovation.
