D.	Risk Factors

Risks Relating to Our Business

This annual report contains forward-looking statements such as forecasts of operating results of operations, management strategies, objectives and plans, forecasts of operational data such as the expected number of subscription, and the expected dividend payments. All forward-looking statements that are not historical facts are based on management’s current plans, expectations, assumptions and estimates based on the information currently available. Some of the projected numbers in this report were derived using certain assumptions that are indispensable for making such projections in addition to historical facts. These forward-looking statements are subject to various known and unknown risks, uncertainties and other factors that could cause our actual results to differ materially from those contained in or suggested by any forward-looking statement. Potential risks and uncertainties include, without limitation, the following:

Changes in the market environment in the telecommunications industry, such as intensifying competition from other businesses or other technologies caused by Mobile Number Portability, development of appealing new handsets, new market entrants, mergers among other service providers and other factors, or the expansion of the areas of competition could limit the acquisition of new subscriptions and retention of existing subscriptions by our corporate group, or it may lead to ARPU diminishing at a greater than expected rate, an increase in our costs, or an inability to reduce expensesoptimize costs as expected.

Mobile Number Portability (“MNP”), the development of appealing handsets, the entry of new service providers, mergers among other service providers and other factors are intensifying competition for our corporate group from other service providers in the telecommunications industry. For example, other mobile service providers have introduced handsets that keep up with the needs and desires of customers, including handsets that support high-speed services and music/video playback, new services such as music and video distribution services, and flat-rate services for voice communications and e-mail, as well as installment sales methods for devices. There are alsoIf, in the future, other providers that offer services related to the convergence of fixed and mobile services, such as aggregated point programs, services offering free calls between fixed-line and mobile phones and discounts for combining fixed line and mobile services, and if services that are highlymore convenient for customers are offered in the future, the Company, which is subject to regulatory constraints, may be limited in its ability to respond in a timely and suitable manner. Furthermore, if other providers offeror handsets that are more appealing than our own handset lineup,to customers in the future, we may be unable to respond in a timely and suitable manner. If we are unable to build a network having a certain area and quality within the anticipated period of time, while other service providers build mobile communications networks with an area and quality that exceeds ours, customer satisfaction with our network may decline.

At the same time, competition is intensifying as a result of the introduction of other new services and technologies, especially low-priced and flat-rate services, such as fixed-line or mobile IP phones (including services that use applications that run on our smartphones and tablets), high-speed broadband Internet service, digital broadcasting, public wireless LAN using Wi-Fi, other free or low-priced services of OTT*OTT^*1 service providers, and so on,the provision of SIM^*2 cards, or a combination of these services.

In addition to competition from other service providers and technologies in the telecommunications industry, there are other factors increasing competition among mobile network operators, such as saturation in the Japanese mobile communications market, changes to business and market structures and the environment due to the expansion of the areas of competition arising from the entry of competitors in the market, including MVNOs*MVNOs^2*3 and competitors from other industries, changes in the regulatory environment, and increased rate competition.industries. With the use of open platform devices like smartphones and tablets becoming increasingly widespread, many businesses and others have entered the competition in service offerings on mobile phones, and in addition, NTT East and NTT West started a wholesale optical-fiber access service which enables a diverse group of market participants to provide services utilizing optical-fiber connections and set discounts for fixed and mobile network services, so it is possible that thosesuch businesses etc.and others may eventually launch services that are more convenient for customers, and further intensify rate competition.

In this market environment, the decline in the number of net new subscriptions we acquire may accelerate in the future and the number of net new subscriptions we acquire may not reach the number we expect. Also, we

may not be able to maintain existing subscriptions as customers migrate to other service providers due to increased competition. Furthermore, in order to capture new subscriptions and maintain existing subscriptions, there could be a greater-than-expected decline in ARPU and/or greater-than-expected costs. In this fierce market environment, in order to provide advanced services and increase convenience to our customers, we have made various revisions, such as in rates and the provision of discounted services. For example, we introduced theflat-rate domestic voice service to our subscribers and the packet flat-rate services for XiLTE (Xi) subscribers. We also introduced “monthly support,” which is a fixed amount discounteddiscount from monthly usage rates set for each equipment type. As additional new fee plans for flat-rate domestic voice services, on June 1, 2014 we also introduced “Kake-hodai & Pake-aeru,” which allows for the sharing of packet telecommunications data volume among family members or the same company or organization, “Zutto DOCOMO Discount,Wari,” a discount service for long-term customers, and “U25 Ouen Discount”Wari” a discount plan for customers 25 up to years of age. In addition, in connection with the commencement of our provision of the “docomo Hikari” optical-fiber broadband service, we launched “docomo Hikari Pack”, which provides the “docomo Hikari” optical-fiber broadband service together with smartphones or mobile phones, on March 1, 2015.

However, we cannot be certain that these rate revisions and discounted services will enable us to acquire new and maintain existing subscriptions. Also, the subscription ratio for various discount services or the trend in migration to flat-rate services may not be in line with the expectations of our corporate group, and our ARPU may decrease more than projected. Furthermore, if market growth slows or the market shrinks, ARPU may decrease even more than our forecast and we may not be able to capture new subscriptions or maintain the existing number of subscriptions at the level we expect. In addition, in order to reinforce our managerial structure, we are promoting increased efficiency related to our network, sales and services, research and development and narrowing our product line-up to concentrate resources. The push toward greater efficiency, however, may not proceed as expected, and costs may not be reducedoptimized as anticipated due to intense competition from other service providers and changes in the market environment.

These foregoing factors may have a material adverse effect on our financial condition and operating results.

If current and new services, usage patterns, and sales schemes proposed and introduced by our corporate group cannot be developed as planned, or if unanticipated expenses arise the financial condition of our corporate group could be affected and our growth could be limited.

We view increases in revenue as an important factor in our future growth. We aim to increase revenue by, for instance, promoting the more widespread use of i-mode services, of smartphone services such as sp-mode, dmenu“dmenu” and dmarket,“dmarket,” and of XiLTE (Xi) services, as well as the expansion of the use of packet communications and other data communications in relation to such services and crowdcloud services like “Shabette-Concier” and the like. Moreover, we look to increase returns through initiatives in new business areas based on the convergence of various businesses and services, such as media/content, finance/payment, commerce, medical/healthcare, Machine-to-Machine (“M2M”)/IoT^*1, environment/ecologyenergy and education/learning with the aim of “realizing a smart life” as another important factor in future growth. However, a number of uncertainties may arise to prevent the development of these services and constrain our growth.

Furthermore, if market growth slows or the market shrinks, the services, forms of usage, and sales methods provided by us may not develop sufficiently which could affect our financial conditions and limit our growth. In particular, we cannot be certain as to whether or not the following can be achieved:

operating systems and applications necessary to promote the use of smartphone and other services, with handset manufacturers, content providers, and with stores that have installed equipment capable of handling e-wallet transactions;

If the development of our corporate group’s new services or forms of use is limited or if development costs are more than anticipated, it may have a material adverse effect on our financial condition and results of operations.

The introduction or change of various laws or regulations inside and outside of Japan, or the application of such laws and regulations to our corporate group, could restrict our business operations, which may adversely affect our financial condition and results of operations.

The Japanese telecommunications industry has been undergoing regulatory reform in many areas, including rate regulation. Because we operate on radio spectrum allocated by the Japanese government, the mobile telecommunications industry in which we operate is particularly affected by the regulatory environment. Furthermore, in some cases, our group is subject to special regulations that are not imposed on other providers.

Various governmental bodies have been recommending or considering changes that could affect the mobile telecommunications industry, and there may be continued reforms, including the introduction or revision of laws, regulations, or systems that could have an adverse effect on us. These include:

In addition to the above proposed changes that may impact the mobile communications business, we may be impacted by a variety of laws, regulations, and systems inside and outside of Japan. For example, in response to an increase in the number of subscriptions or in the traffic volume*²traffic* per subscriber, we have proceeded with the enhancement of our telecommunications facilities in order to ensure and improve our service quality. As a result, we are using an increasing amount of electricity. Moreover, we are implementing measures directed towards reducing greenhouse gas emissions, including deployment of low-power consumption devices and efficient power generators. However, with the implementation of regulations and other measures aimed at reducing greenhouse gas emissions, our cost burdens may increase, and this may have an adverse effect on our financial condition and results of operations. Also, the financial condition and operating results of our corporate group may be adversely affected by the increased cost of maintaining and operating the facilities we require for providing our services on account of electricity cost increases due to high fuel prices. In July 2010 the Dodd–“Dodd–Frank Wall Street Reform and Consumer Protection ActAct” was signed into law in the U.S.United States. Based on this, the USU.S. Securities and Exchange Commission established rules in August 2012 requiring listed companies that use designated minerals in their products to disclose whether such minerals come from the Democratic Republic of the Congo and adjoining countries. The implementation of these rules could have an adverse effect on our financial condition and operating results in the form of higher costs arising from expense of conducting the research needed for regulatory compliance or from an increase in the prices of materials that use such minerals.

Further still, in order to ensure new sources of revenue, we are pursuing initiatives to create new value through the convergence of mobile services with various services and industries, including media/content, finance/payment, commerce, medical/healthcare, M2M,M2M/IoT, environment/ecology, energy, education/learning and other fields through equity participation and partnerships. Therefore, we are vulnerable to the impact of laws, regulations and systems specific to new services, operations and areas of business, in addition to the laws, regulations and systems applicable to the mobile communications business. If such laws, regulations, or systems are implemented, they may work as constraints on our group’s business operations, and this may have an adverse effect on our group’s financial condition and corporate performance.

It is difficult to predict with certainty if any proposed changes impacting the mobile telecommunications business, or if any other relevant laws, regulations or systems will be drafted, and if they are implemented, the extent to which our business will be affected. However, if any one or more of the above proposed changes impacting the mobile telecommunications business occurs, or if laws, regulations or systems are introduced, reformed, or become applicable to us, we may experience constraints on the provision of our mobile communication services, which may have an adverse effect on our financial condition and results of operations.

Limitations in the amount of frequency spectrum or facilities made available to us could negatively affect our ability to maintain and improve our service quality and level of customer satisfaction and could increase our costs.

One of the principal limitations on a mobile communication network’s capacity is the available radio frequency spectrum we can use. There are limitations in the spectrum and facilities available to us to provide our services. As a result, in certain parts of metropolitan Tokyo and Osaka, such as areas near major train stations, our mobile communication network operates at or near the maximum capacity of its available spectrum during peak usage periods, which may cause reduced service quality.

Furthermore, with the number of subscriptions and traffic volume per subscriber increasing, our service quality may decline if we cannot obtain the necessary allocation of spectrum from the Japanese government for the smooth operation of our business.

Even though our corporate group plans to establish specified base stations to use the allocated 700MHz band as soon as the operating conditions are met, if measures for acceleration (acceleration measures for termination) of the transfer of existing FPU*FPU^* and specified radio microphones that are currently using this spectrum do not proceed as anticipated, our corporate group may not be able to operate the mobile communication network smoothly, service quality may decline, and additional expenses may arise.

Although we are working to improve the efficiency of our spectrum use through technology such as LTE/LTE-Advanced, including migration to LTE and other measures and to acquire additional spectrum, we may be unable to avoid a reduced quality of services.

In addition, due to the limited processing capacity of our base stations, switching facilities, and other equipment necessary for providing services, the quality of the services we provide may also decrease during peak usage periods if our subscription base dramatically increases or the volume of content such as images and music provided through our networks significantly expands. Also, in relation to our FOMA and XiLTE (Xi) services, the growth in the number of service subscribers and traffic volume per subscriber could significantly exceed our expectations due to the proliferation of smartphones and tablets as well as data communication devices for PCs. Furthermore, some of the software that runs on smartphones and tablets could result in greater use of control signals (the signals exchanged between devices and the network) in order to establish and terminate communications, and could therefore put a greater-than-anticipated burden on our facilities. If it becomes impossible to process such traffic using our existing equipment, service quality may deteriorate, communication interruptions may arise and the cost of investing in equipment to address these issues could increase.

We are endeavoring to reinforce the network foundation in order to cope with future increases in smartphone traffic. If unforeseen circumstances should arise, such as communication interruptions due to an increase in the number of subscribers and traffic volume and/or control signals per subscriber, and we are not able to address such problems sufficiently and in a timely manner, our ability to provide mobile communication services could be constrained or we could lose customers’ trust, and as a result, we could lose subscribers to our competitors. At the same time, the cost of investing in equipment to address these issues could increase, and this could materially affect our financial condition and results of operations.

Other mobile service providers in the world may not adopt the technologies and the frequency bands that are compatible with those used by our corporate group’s mobile communications system on a continuing basis, which could affect our ability to sufficiently offer international services.

We are able to offer global roaming services on a worldwide basis on the condition that a sufficient number of other mobile service providers have adopted technologies and frequency bands that are compatible with those we use on our mobile communications systems. We expect that our overseas affiliates, strategic partners and many other mobile service providers will continue to use the technologies and the frequency bands that are compatible with ours, but there is no guarantee of this in the future.

If a sufficient number of mobile service providers do not adopt the technologies and the frequency bands that are compatible with ours, if mobile service providers switch to other technologies or frequency bands, or if there is a delay in the introduction and expansion of compatible technologies and frequency bands, we may not be able to offer international roaming or other services as expected, and we may not be able to offer our subscribers the convenience of overseas services.

Also, we cannot be sure that handset manufacturers or manufacturers of network equipment will be able to appropriately and promptly adjust their products if we need to change the handsets or network we currently use due to a change in the standard technology we adopt, resulting from the activities of standards organizations.

If such technologies and frequency bands compatible with those we have adopted do not develop as we expect and if we are not able to maintain or improve the quality of our overseas services, our financial condition and results of operations may be adversely affected.

Our domestic and international investments, alliances and collaborations, as well as investments in new business fields, may not produce the returns or provide the opportunities we expect.

One of the major components of our strategy is to increase our corporate value through domestic and overseas investments, alliances and collaborations. We have entered into alliances and collaborations with other companies and organizations overseas which we believe can assist us in achieving this objective. We are also promoting this strategy by investing in, entering into alliances with, and collaborating with domestic companies and investing in new business fields.

However, there can be no assurance that we will be able to maintain or enhance the value or performance of the past or future investments or joint ventures established, or that we will receive the returns or benefits we expect from these investments, alliances and collaborations. In our investments in new business fields outside of the mobile telecommunication business, such as media/content, finance/payment, commerce, medical/healthcare, M2M,M2M/IoT, environment/ecology, energy, education/learning and the like, anticipated synergies may not be realized due to uncertain and unforeseeable ancillary factors, as we have little experience in such new fields of business, and these factors may have an impact on our strategy. Furthermore, losses may arise due to dissolution or divestiture of investments, alliances and collaborations.

In recent years, the companies in which we have invested have experienced a variety of negative impacts, including severe competition, increased debt burdens, significant change in share prices and financial difficulties.

To the extent that these investments are accounted for by the equity method and to the extent that the investee companies have net losses, our financial results will be adversely affected by ourpro rata portion of these losses. If there is a loss in the value of our investment in any investee company and it is not regarded as a temporary decline, our corporate group may be required to adjust the book value and recognize an impairment loss for such investment. Also, a business combination or other similar transaction involving any of our investee companies could require us to realize impairment loss for any decline in the value of investment in such investee company. In either event, our financial condition or results of operations could be materially adversely affected.

Malfunctions, defects or imperfections in our products and services or those of other parties may give rise to problems.

Various functions are mounted on the mobile handsets we provide. Additionally, a large number of vendors, including our partners and other companies, provide services via the mobile handsets that we provide. If any problems arise due to the imperfection in a product or service provided by the Company or by another vendor such as technological problems in the handsets provided by us or by outside vendors or in software or systems, or if any other failures, defects, or losses arise, such problems could diminish our credibility or corporate image, lead to an increase in cancellations of subscriptions, or result in an increase in expenses for indemnity payments to subscribers, and our financial condition or results of operations may be affected. Furthermore in an effort to ensure new sources of revenue, we are pursuing initiatives toward the expansion of new businesses through the convergence of mobile service with various other services and industries, including media/content, finance/payment, commerce, medical/healthcare, M2M,M2M/IoT, environment/ecologyenergy and education/learning. Should problems arise due to the imperfection in such products or services, they could diminish our credibility or corporate image and our financial condition or results of operations may be affected. Certain events may lead to a decrease in our credibility and corporate image, an increase in cancellations of subscriptions or increased costs. The following are possible examples of such events:

Social problems that could be caused by misuse or misunderstanding of our products and services may adversely affect our credibility or corporate image.

We may face an increase in cancellations of subscriber contracts and difficulty in acquiring new subscriptions due to decreased credibility of our products and services and damaged corporate image caused by inappropriate use of our products and services by subscribers.

For example, there are cases of unsolicited bulk e-mails being sent through our e-mail services, including docomo mail, sp-mode mail, i-mode mail and SMS. Despite our extensive efforts to address this issue caused by unsolicited bulk e-mails, including notifying our subscribers via various brochures, providing unsolicited bulke-mail filtering functions with our handsets and suspending our services to companies which distribute large

amounts of such unsolicited bulk e-mails, the problem has not yet been rooted out. If our subscribers receive a large amount of unsolicited e-mail, it may cause a decrease in customer satisfaction and may damage our corporate image, leading to a reduction in the number of sp-mode or i-mode subscriptions.

The mobile phones used in connection with crimes such as billing fraud are most often rental mobile phones. To combat these misuses of our services, we have introduced various measures such as refusing to provide services to unscrupulous mobile phone rental companies that violate the Mobile Phone Improper Use Prevention Act, such as by not confirming the identity of the individual at the time of rental. However, in the event that criminal usage increases, mobile phones may be regarded as a societal problem, which may lead to an increase in the cancellation of contracts.

In addition, problems have arisen from the fact that subscribers were charged fees for packet communication at higher levels than they anticipated as a result of using mobile phones without fully recognizing the increased volume and frequency of the use of packet communications as our handsets and services became more sophisticated. There have also been problems with high charges due to excessive use of paid content services, and problems due to an increasing amount of trouble and number of accidents caused by the use of mobile phones while driving, riding a bicycles or walking. Further, there are currently a variety of discussions concerning such issues as the pros and cons of elementary and junior high schools students having mobile phones, the sufficiency and accuracy of our access restriction service to screen harmful web sites (“filtering service”), which applies generally to subscribers under 20 years of age in accordance with the enactment of the Act on Establishment of Enhanced Environment for Youth’s Safe and Secure Internet Use, and the increase in harm caused by the use of CGM* by young people, as they increasingly have access to the Internet from their mobile phones. These issues may similarly damage our corporate image.

We believe that we have properly addressed the social issues involving mobile phones by providing various services such as a filtering service and access restriction services with user age authentication and cell phones specifically designed for young people. However, it is uncertain whether we will be able to continue to respond appropriately to those issues in the future. Should we fail to do so, we may experience an increase in the cancellation of existing subscriber contracts or fail to acquire new subscribers as expected, and this may affect our financial condition and results of operations.

Inadequate handling of confidential business information including personal information by our corporate group, contractors and others, may adversely affect our credibility or corporate image.

We possess information on numerous subscribers in telecommunications, credit, catalog sales and other businesses, and to appropriately and promptly address the Law Concerning the Protection of Personal Information, we have put in place comprehensive company-wide security management that includes thorough management of confidential information such as personal information, employee education, supervision of subcontractors and the strengthening technological security.

However, in the event an information leak occurs despite these security measures, our credibility and corporate image may be significantly damaged and we may experience an increase in cancellation of subscriber contracts, an increase in indemnity costs and slower increase in additional subscriptions, and our financial condition and results of operations may be adversely affected.

Owners of intellectual property rights that are essential for our business execution may not grant us a license or other use of such intellectual property rights, which may result in our inability to offer certain technologies, products and/or services, and our corporate group may also be held liable for damage compensation if we infringe the intellectual property rights of others. In addition, the illicit use by a third party of the intellectual property rights owned by our corporate group could reduce our license revenues actually obtained and may inhibit our competitive superiority.

For us and our business partners to carry out our business, it is necessary to obtain licenses and other rights to use the intellectual property rights of third parties. Currently, we are obtaining licenses from the holders of the rights concerned by concluding license agreements. We will obtain the licenses from the holders of the rights concerned if others have the rights to intellectual property necessary for us to operate our business in the future. However, if we cannot come to an agreement with the holders of the rights concerned or a mutual agreement concerning the granted rights cannot be maintained afterwards, there is a possibility that we or our business partners might not be able to provide our specific technologies, products or services. Also, if we receive claims of violation of intellectual property rights from others, we may be required to expend considerable time and expense to reach a resolution. If such claims are acknowledged, we may be liable to pay damages for infringement of the rights concerned, which may adversely affect our financial condition and results of operations.

Furthermore, the illicit use by a third party of the intellectual property rights owned by our corporate group could reduce our license revenues actually obtained and may inhibit our competitive superiority.

Events and incidents caused by natural disasters, social infrastructure paralysis such as power shortages, the proliferation of harmful substances, terror or other destructive acts, the malfunctioning of equipment, software bugs, deliberate incidents induced by computer viruses, cyberattacks, equipment misconfiguration, hacking, unauthorized access and other problems could cause failure in our networks, distribution channels, and/or other factors necessary for the provision of service, disrupting our ability to offer services to our subscribers, and such incidents may adversely affect our credibility or corporate image, or lead to a reduction of revenues and/or increase of costs.

We have built a nationwide network, including base stations, antennas, switching centers and transmission lines, and provide mobile communication service using this network. In order to operate our network systems in a safe and stable manner, we have various measures in place, such as duplicative systems. However, despite these measures, our system could fail for various reasons, including malfunctioning of system hardware and software, natural disasters such as earthquakes, tsunamis, typhoons and floods, paralysis of social infrastructure, such as power shortages, terrorism, and similar events and incidents, and the inability to sufficiently operate and maintain network facilities due to, for example, the proliferation of harmful substances or the spread of an epidemic. These system failures can require an extended time for repair and, as a result, may lead to decreased revenues and significant cost burdens, and our financial condition and results of operations may be adversely affected.

There have been instances in which tens of millions of computers worldwide were infected by viruses through fixed line Internet connections. As smartphones become more widespread, however, a growing number of viruses are also targeting mobile handsets. Similar incidents could occur on our networks, handsets, or other equipment. If such a virus entered our network or handsets or other equipment through such means as hacking, unauthorized access, or otherwise, or if there was a cyber -attack, our system could fail, the services we provide could become unusable service quality could be impacted and/or confidential information could be leaked. In such an instance, the credibility of our network, handsets and other equipment and customer satisfaction could decrease significantly. Although we have enhanced security measures including systems to block unauthorized access, remote downloading for mobile phones, and the provision of “Anshin Net Security,” an antivirus solution for smartphones in order to provide for unexpected events, such precautions may not make our system fully prepared for every contingency. Moreover, software bugs, incorrect equipment settings, and human errors that are not the result of malfeasance could also result in system failures, diminished service quality, or leaks of confidential information.

In addition, events or incidents caused by natural disasters, social infrastructure paralysis, the proliferation of harmful substances, the spread of an epidemic, or any other event could force our offices or critical business partners, including sales agencies, to suffer constraints on business operations or to temporarily close their offices or stores. In such a case, we would lose the opportunity to sell or provide goods and services and also may not be able to respond appropriately to subscription applications and requests from subscribers, such asafter-sales service requests.

If we are unable to properly respond to any such events, our credibility or corporate image may decrease, and we may experience a decrease in revenues as well as significant cost burdens, and if market growth slows or the market shrinks due to any such event, ARPU may decrease below our forecast, or we may not be able to gain new subscriptions or maintain the existing number of subscriptions at the level we expect. All of these factors may affect our financial condition and results of operations.

Concerns about adverse health effects arising from wireless telecommunications may spread and consequently adversely affect our financial condition and results of operations.

Reports by the World Health Organization (WHO), other organizations andThrough various media sources have suggestedand the internet, information has been disseminated indicating that there is concern about whether radio wave emissions from mobile handsets and other wireless telecommunications devices may adversely affect people’s health or may interfere with various electronic medical devices including hearing aids and pacemakers or may adversely affect the health of their users and others by causing cancer or other diseases. Concernscardiac pacemakers. Such concerns about the risk ofpossible risks associated with wireless telecommunication devices adversely affecting the health of users could adversely affect our corporate image, financial condition, and results of operations through increased cancellations by existing cellular subscribers, reduced subscriber growth, reduced usage per subscriber, and the introduction of new regulations or restrictions or litigation. The radio emissions from our cellular handsets and base stations comply with the electromagnetic safety guidelines of Japan andestablished by the Japanese government, which are equivalent to the international guidelines byof the International Commission on Non-Ionizing Radiation Protection, which are endorsed by the WHO.World Health Organization “WHO.” The WHO has also stated that if the level of the radio emissionemissions from mobile devices is lower than the international guidelines, it wouldwill not affect the health of their users and others. Research and studies on the effect of radio wave emissions on people’s health are ongoingbeing conducted by foreign research institutes such as the WHO and we are actively attempting to confirm the safetyMinistry of wireless telecommunication, butInternal Affairs and Communication, or the MIC. While no evidence of an adverse effect on people’s health has been found as of yet, there can be no assurance that, further research and studies will demonstrate that there is no interrelationgoing forward a link between radio wave emissions and health problems.problems will not be identified in the results of future research or studies.

Furthermore, the Ministry of Internal Affairs and CommunicationsMIC and the Electromagnetic Compatibility Conference Japan have confirmed that some electronic medical devices aresuch as cardiac pacemakers can be affected by the electromagnetic interference from cellular phones as well asand other portable radio transmitters.wireless equipment, and has created guidelines on safe usage to provide information to the general public. We are working to provide information to ensure that our subscribers are sufficiently aware of these precautions when using cellular phones. There is a possibility that modifications to regulations and new regulations or restrictions could limit our ability to expand our market or our subscription base or otherwise adversely affect us.

Our parent company, NIPPON TELEGRAPH AND TELEPHONE CORPORATION (NTT),NTT, could exercise influence that may not be in the interests of our other shareholders.

As of March 31, 2014,2015, NTT owned 66.65% of our outstanding voting shares. While being subject to the conditions for fair competition established by the Ministry of Posts and Telecommunications (“MPT,” currently(currently the Ministry of Internal Affairs and Communications, or “MIC”)MIC) in April 1992, NTT retains the right to control our management as a majority shareholder, including the right to appoint directors. Currently, although we conduct our day-to-day operations independently of NTT and its other subsidiaries, certain important matters are discussed with, or reported to, NTT. As such, NTT could take actions that are in its best interests but may not be in the interests of our other shareholders.

Risks Relating to the Shares and the ADSs

Future sales of our shares by NTT or by us may adversely affect the trading price of our shares and ADSs.

As of March 31, 2014,2015, NTT owned 66.65% of our outstanding voting shares. Under Japanese law, NTT, like any other shareholder, generally is able to dispose of our shares freely on the Tokyo Stock Exchange or otherwise. Additionally, our boardBoard of directorsDirectors is authorized to issue 13,095,000,00013,374,228,000 additional shares generally without any shareholder approval. The sale or issuance or the potential for sale or issuance of such shares could have an adverse impact on the market price of our shares.

There are restrictions on your ability to withdraw shares from the depositary receipt facility.

Each ADS represents the right to receive one share of common stock. Therefore, pursuant to the terms of the deposit agreement with our depositary, The Bank of New York Mellon, in order to withdraw any shares, a holder of ADSs must surrender for cancellation and withdrawal of shares using ADRs (each of which evidences 1ADSs). As a result, holders of ADSs will be unable to withdraw fractions of shares from the depositary or receive any cash settlement in lieu of withdrawal of fractions of shares. In addition, although the ADSs themselves may be transferred in any lots pursuant to the deposit agreement, the ability to trade the underlying shares may be limited.

Holders of ADRs have fewer rights than shareholders and have to act through the depositary to exercise those rights.

Holders of ADRs do not have the same rights as shareholders and accordingly cannot exercise rights of shareholders against us. The Bank of New York Mellon, as depositary, through its custodian agent, is the registered shareholder of the deposited shares underlying the ADSs, and therefore only it can exercise the rights of shareholders in connection with the deposited shares. In certain cases, we may not ask The Bank of New York Mellon to ask holders of ADSs for instructions as to how they wish their shares voted. Even if we ask The Bank of New York Mellon to ask holders of ADSs for such instructions, it may not be possible for The Bank of New York Mellon to obtain these instructions from ADS holders in time for The Bank of New York Mellon to vote in accordance with such instructions. The Bank of New York Mellon is only obliged to try, as far as practical, and subject to Japanese law and our Articles of Incorporation, to vote or have its agents vote the deposited shares as holders of ADSs instruct. In your capacity as an ADS holder, you will not be able to bring a derivative action, examine the accounting books and records of the Company, or exercise appraisal rights.

U.S. investors may have difficulty in serving process or enforcing a judgment against us or our members of the board of directors, executive officers or audit & supervisory board members.

We are a limited liability, joint stock corporation incorporated under the laws of Japan. Most of our members of the board of directors, executive officers and audit & supervisory board members reside in Japan. All or substantially all of our assets and the assets of these persons are located in Japan and elsewhere outside the United States. It may not be possible, therefore, for U.S. investors to effect service of process within the United States upon us or these persons or to enforce against us or these persons judgments obtained in U.S. courts predicated upon the civil liability provisions of the Federal securities laws of the United States. There is doubt as to the enforceability in Japan, in original actions or in actions for enforcement of judgment of U.S. courts, of liabilities predicated solely upon the federal securities laws of the United States.

Rights of shareholders under Japanese law may be different from rights of shareholders in jurisdictions within the United States.

Our Articles of Incorporation, Regulations of the Board of Directors and the Companies Act of Japan (Kaishaho), or Companies Act) govern our corporate affairs. Legal principles relating to such matters as the validity of corporate procedures, directors’ and officers’ fiduciary duties and liabilities, and shareholders’ rights under Japanese law

may be different from those that would apply to a company incorporated in a jurisdiction

within the United States. You may have more difficulty in asserting your rights as a shareholder than you would as a shareholder of a corporation organized in a jurisdiction within the United States.

Our shareholders of record on a record date may not receive the dividend they anticipate.

The customary dividend payout practice and relevant regulatory regime of publicly listed companies in Japan may differ from that followed in foreign markets. While we may announce forecasts of year-end and interim dividends prior to the record date, these forecasts are not legally binding. The actual payment of year-end dividends requires a resolution of our shareholders. If the shareholders adopt such a resolution, the year-end dividend payment is made to shareholders as of the applicable record date, which is currently specified as March 31 by our Articles of Incorporation. However, such a resolution of our shareholders is usually made at an ordinary general meeting of shareholders held in June. The payment of interim dividends requires a resolution of our boardBoard of directors.Directors. If the board adopts such a resolution, the dividend payment is made to shareholders as of the applicable record date, which is currently specified as September 30 by our Articles of Incorporation. However, the board usually does not adopt a resolution with respect to an interim dividend until September 30.

Shareholders of record as of an applicable record date may sell shares after the record date in anticipation of receiving a certain dividend payment based on the previously announced forecasts. However, since these forecasts are not legally binding and resolutions to pay dividends are usually not adopted until after the record date, our shareholders of record on record dates for year-end or interim dividends may not receive the dividend they anticipate.

In the Japanese mobile telecommunicationscommunications market, besidesin addition to the intense competition that we engagerapid proliferation and expansion in withuse of smartphones, tablets and other Japanese telecommunications carriersfunction-rich mobile devices, due to active movementthe government’s policy of subscribers usingpromoting of the spread of Mobile Number Portability (MNP) system, weVirtual Network Operators (“MVNOs”) and other factors, various new market participants are also facing competition withexpected to continue to enter the market and many new players offering a wide variety ofInternet-basedservices that transcend the scope of traditional telecommunications businesses.are expected to continue to be invented.

There are presently 3three mobile network operators in Japan: DOCOMO, KDDI CORPORATION and its subsidiaries (“KDDI group”) and SoftBank Corp. and its subsidiaries (“SOFTBANK group”). As of March 31, 2014,2015, we had a market share of 43.8%43.6%, KDDI group had a market share of 28.1%28.5% and SOFTBANK group had a market share of 28.1%27.9%.

As of March 31, 20142015 we had approximately 63,10566,595 thousand cellular subscribers, an increase of 1,5693,490 thousand from the end of the previous fiscal year. Also, our cellular churn rate for March 20142015 was 0.87%0.71%.

Although future growth of new subscribers for conventional voice use is expected to be limited as the penetration rate rises and the population declines, in recent years, the development of new markets for products such as smartphones,demand for second devices such as tablets data cards and mobile Wi-Fi routers, in addition to embedded communication modules, and rising numbers of subscribers due to an increase in corporate subscriptions, have helped drive growth in new subscriptions.

The number of cellular subscriptions for the fiscal years ended March 31, 2012, 2013, 2014 and 20142015 are as follows:

*active cellular subscriptions = (number of subscriptions at the end of previous month + number of subscriptions at the end of current month) / 2

In the Japanese mobile communicationFurthermore, Japan’s telecommunications sector has seen a dramatic change in its market new market opportunities, such as content and applications for mobile phones, are emerging while the usage of data communications is increasing in line with the increased use of smartphones and penetration of high-speed data communication services. Mobile network operators, including DOCOMO, are competing to maintain and obtain subscribers and to create new revenue sources, endeavoring to expand area coverage and increase the speed of their LTE networks, provide devices with special features such as various user interfaces and functions, implementing new billing measures, promoting handset sales, and provide added-value services.structure.

In recent years, as smartphonesMay 2014, NTT unveiled its “Hikari Collaboration Model”—a new wholesale business model for its fiber access services. As this enables telecommunications operators and tablets have become more popular, there has been a growing movement among competitorswide range of other market participants to bundle mobile phoneprovide services with fixed-line communication services andutilizing fiber connections, the competition in the market is expected to discount those charges. However, dueintensify even further, transcending the traditional boundaries of the telecommunications business.

Due to government regulations, we are prohibited from partnering exclusively within the NTT group, and similarwe have been unable to partner with NTT group companies to provide packages of mobile phone and fixed communication services cannot be implemented. or offer discount services such as those which have become popular among rival companies in recent years.

Meanwhile, we also plan to move ahead to offer attractive services combining fixed-line services and our mobile communications services in response toby accepting the announcementwholesaling of “Hikari Collaboration Model”, which provides wholesaling fiber access services provided by NTT East and NTT West, it has become possible to other companiesprovide optical-fiber broadband service ourselves from NIPPON TELEGRAPH AND TELEPHONE EAST CORPORATIONMarch 2015, we launched the “docomo Hikari” service (DOCOMO’s optical-fiber broadband service) and NIPPON TELEGRAPH AND TELEPHONE WEST CORPORATION“docomo Hikari Pack,” making the first step in our journey for offering new added value through the future. Moreover, currently, the Ministryconvergence of Internal Affairsfixed-line and Communications is undertaking a review of the government’s datamobile communications policy with a view to considering reform in competition policy, and intends to prepare a report by the end of 2014.

Furthermore, competition in the network layer has intensified due to the increasing number of new MVNOs, with foreign companies also among them, in addition to existing mobile phone network operators. The arrival of global players, including Apple Inc., Google Inc., Amazon.com, Inc., and Facebook, Inc. has also accelerated the shift from the vertical integration model led by existing mobile phone network operators to a model of horizontal division and has given vigor to a new vertical integration model in which the key is the platform as well as operation system, terminal, content, application, and other upper layers.

As stated above, althoughAlthough our business environment is severe, as stated above, due to the market environment, regulations and changes in our business model, we are endeavoring to strengthen our competitiveness based on the business strategy described below.

We have been taking steps to reinforcedeveloped our competitiveness in the mobile business by thoroughly improving our offerings and developing attractive services in our new business fields, based on our medium-term business plan: “Medium-Term Vision 2015: Shaping acorporate vision for 2020, “HEART: Pursuing Smart Life.”

In the fiscal year ended March 31, 2014, we strived to boost our comprehensive strengths by focusing on the four key areas of “devices (handsets),” “network,” “services” and “billing plans and sales channel,” with the goal of being chosen by a large number of customers and garnering their usage over a long period of time.

Furthermore, in orderInnovation” to propel the expansion of ourfurther growth and propose new businesses going forward, we pursued collaboration and alliances with external partners to provide new services in various sectors such as “healthcare” and “learning.”

Meanwhile, to add momentum to the initiatives mentioned above, we strived to strengthen our managerial foundation through structural reforms, stepping up cost-cutting efforts and shifting management resources to new business fields.

Furthermore, in April 2014, we unveiled a new billing plan called “Kake-hodai & Pake-aeru” which offers unlimited domestic voice calls for a flat monthly rate and enables users to share their packet-data quota among family members, and introduced a new discount for young customers up to the age of 25 and discounts according to the number of years of use, with the goal of enabling customers to utilize our services at affordable rates for a long period of time by selecting a plan appropriate for their individual needs in different stages of life.

Going forward, we will continue our efforts to bring greater happiness to the lives of our customers and their families, andvalues to society within anticipation of future social changes.

Also, under the goalbanner of becoming a “Partner for smart life” of our customers, we tackled the challenge of “reinforcing our competitiveness in telecommunications business” and “stepped up our efforts in the smart life business and other businesses.”

In April 28, 2015, we announced our medium-term initiatives and the Business Management Policies for FY2015 (year ending March 31, 2016).

Initiatives for the medium-term

To respond to customer needs on an ongoing basis, we will implement initiatives for “co-creation”—an effort to create new added value together with various external partners by constantly evolving the format of collaboration.

As presented in “Medium-Term Vision 2015,” we have hitherto worked on new value creation centered on mobile communications by pursuing convergence with other industries and services. Going forward, we will further advance these undertakings and embark on a Smart Life,new initiative dubbed “+d”—a joint value creation initiative that we plan to promote together with partners, making available to our partners our own business assets, such as our payment platform and point program, etc. To further accelerate this initiative, we will standardize the names of the various services that we offer. In the new arrangement, our services will begin with the letter “d,” chosenso customers can easily appreciate the various DOCOMO services that they can utilize.

We will also work to offer new values to various partners, further evolving the forms of collaboration, which have so far been centered on value creation for consumers. Specifically, in the areas of “IoT,” “Regional Revitalization,” “2020*,” and patronized“Solution of Social Issues,” we will strive to create new services and businesses in collaboration with partners utilizing the assets of both parties, with the goal of capturing new revenue opportunities in new domains that transcend the confines of our current industries or business formats.

Through the abovementioned initiatives, we will aim to expand the smart life business and other businesses while accommodating customer requirements.

FY2015 Business Management Policies

We developed our FY2015 Business Management Policies, positioning FY2015 as the year of making a solid step toward the achievement of our medium-term growth. Considering the attainment of operating income target a matter of utmost importance, we will take actions aimed at increasing our telecommunications services revenues, expanding the smart life business and other businesses and improving our cost efficiency.

We will continue to engage ourselves in co-creation of added value for customers in collaboration with partners, so that what is perceived as new today can be taken for a long period of time.granted in the future.

2. Networks

We currently provide our services mainly on LTE and W-CDMA networks.

In December 2010, we launched LTE (Long Term Evolution) service for data communications devices. In November 2011, we expanded the service to smartphones. We are utilizingcontinue our efforts to take advantage of our experience and expertise as a LTE service pioneer to build a robust network pursuing “breadth,” “speed” and expanding “Quad-Band LTE^*1,“convenience.” which makes maximum use of the four different spectrum bands we own. We are endeavoring to provide a high quality communications environment offering faster speeds and broader reach in future.

In termsthe fiscal year ended March 31, 2015, the total number of expanding our service area, we had increased ourLTE base stations was increased to 97,400 stations from 55,300 nationwidestations as of March 31,2014 (an increase of 30,900 stations compared31, 2014 to the number a year ago) surpassing our initial target of 50,000.

In addition, tofurther improve the communication quality in urban centers and other areasarea coverage of high usage, we moved ahead with the installation of “6-sector base stations^*2” that can handle the same capacity as six regular base stations with a single site.our LTE service.

We commencedoffer high-speed LTE service that offersrealizes a maximum download speed of 150Mbps*³150Mbps in the Tokyo, Nagoya and Osaka metropolitan areas, while expandingareas. Also, in pursuit of further enhancement of transmission speeds, we increased the service areasnumber of our maximum 112.5Mbps downlink speed service to all 47 prefectures of Japan.

During fiscal 2014, we also intend to provide high speed transmission servicesLTE base stations compatible with a maximum receptiondownload speed of 100Mbps or higher to 57,700 stations from 3,500 stations as of March 31, 2014.

In March 2015, we launched the “PREMIUM 4G” service that delivers downlink speeds of up to 225Mbps using the LTE-Advanced carrier aggregation.system, which incorporates “carrier aggregation ^*1,” “advanced C-RAN ^*2” and other technologies that realize further speed/capacity enhancements over LTE service.

The Ministry of Internal Affairs and Communications (“MIC”)MIC has allocated a total bandwidth of approximately 400MHz530MHz as radio frequencies available for use for LTE/W-CDMA networks (2GHz,(3.5GHz, 2GHz, 1.7GHz, 1.5GHz, 900MHz, 800MHz, 700MHz and 2GHzTDD). Of this, we use 4have been allocated 6 frequency bands—3.5GHz, 2GHz, 1.7GHz, 1.5GHz, 800MHz and 800MHz—700MHz—to operate our networks.

2GHz Band:

The 20MHz x 2 allocated in the 2GHz band is jointly used by our LTE and W-CDMA networks. A maximum 15MHz x 2 is used for our LTE network.

1.7GHx Band:

The 20MHz x 2 in the 1.7GHz band is jointly used by our LTE and W-CDMA networks in the Kanto, Kansai and Tokai areas. We also intend to expand use for the LTE network in the future.

1.5GHz Band:

The 15MHz x 2 allocated in the 1.5GHz band is used by our LTE network.

800MHz Band:

The 15MHz x 2 allocated in the 800MHz band is jointly used by our LTE and W-CDMA networks. The maximum 15MHz x 2 is used for our LTE network.

700MHz Band:

With regard to our plan to open specified base stations to be used for the 700MHz band, approval was received from the Minister of MIC in MayJune 2012. In addition, the Association of 700MHz Frequency Promotion was established by 4 operators (NTT DOCOMO, Inc., KDDI Corporation, eAccess Ltd. (currently SoftBank Mobile Corp.) and Okinawa Cellular Telephone Company) that were approved at the same time. Together with the appropriate transfer of new frequency bands to existing licensees currently using the frequencies, receiver measures for overland digital TV broadcasts are being implemented. We plan to start providing LTE services as of Januarythe first quarter of fiscal year 2015 for the 10MHz x 2 allocated in the 700MHz band.

In addition, in order3.5GHz Band:

With regard to respondour plan to increased traffic we are seekingopen specified base stations to allocate additional bands of spectrum such as 3.5GHz and 1.7GHz. Asbe used for the 3.5GHz band, at the public hearings on fourth-generation mobile communications systems that started in January 2014, besides explaining the usage methods for 3.5GHz if the band is allocated for us, we expressed the opinion that as many frequency bands as possible should be allocated to our companyapproval was received from the perspectiveMinister of ensuring an equitable competitive environment.

For providing customers with a stable and comfortable communication environment, we moved ahead with the reinforcement of our network facilities to respond to the increase in data traffic resulting from the expanded adoption of smartphones. For example, we expanded the LTE network capacity, utilized transmission speed controls for data communication by especially heavy users for data communications and offloaded data to “docomo Wi-Fi.”

In addition, to prepare for possible large-scale disasters, such as an earthquake directly striking the Tokyo metropolitan area, we have taken various measures such as the dispersion of important communications facilities previously concentrated in the metropolitan area, securing emergency power sources, and making it possible to switch to power saving mode via remote control.

Furthermore, in order to establish and maintain our high-quality network economically and efficiently, we provide fair competitive opportunities, foster mutual understanding and build trusting relationships with suppliers, and purchase high-quality network equipment at low cost from suppliers inside and outside Japan in accordance with our procurement policies, which emphasize compliance with CSR and various laws.
