Notice of the Result of the Tender Offer for Repurchase of Shares

NTT DOCOMO, Inc. (“the Company”) resolved at a meeting of the Board of Directors on December 11, 2017 to repurchase the treasury stock by means of a Tender Offer (the “Tender Offer”), using the acquisition method specified under Article 156, Paragraph 1 of the Companies Act, as applied pursuant to the provisions of Article 165, Paragraph 3 of the same Act, and the provisions of the Company’s Articles of Incorporation, and has implemented the “Tender Offer” since December 12, 2017. The “Tender Offer” was completed on January 15, 2018. Details are set forth below. With respect to the Company’s acquisition of treasury stock (through repurchases on the market) after the completion of the Tender Offer, the Company will make such repurchases in accordance with the Company’s notice disclosed on December 11, 2017.

Notification of the purchases under the tender offer will be sent to the address of those who consent to offers for purchases or offer for sales (“Tendering Shareholders”) (or the standing proxy for foreign shareholders) after the conclusion of the tender offer period without delay.

Purchases will be settled in cash. Tendering Shareholders will be able to receive the purchase amount for the tender offer, less applicable withholding taxes (see note), by wire transfer or other method as instructed by the tendering shareholder without delay after the settlement commencement date (wire transfer fees may apply).

Note: Taxes on shares purchased under the tender offer

* Please make any decisions after consulting a tax advisor or other professional about specific tax questions.

(a)

Tax treatment for individual shareholders tendering shares under the tender offer

(i)

For Tendering Shareholders who are residents, or non-residents with a permanent establishment in Japan

When the amount of money received for accepting the tender offer exceeds the amount of the portion of the Company’s capital (or for a consolidated corporation, its consolidated individual stated capital) attributable to the shares that are the basis for that payment (when the per-share purchase amount is greater than the per-share amount of capital), the amount in excess will be deemed a dividend and taxed accordingly. Furthermore, the amount derived after deducting the amount deemed to be a dividend from the amount received for accepting the tender offer will be deemed income from the transfer of shares. When there is no amount deemed to be a dividend (when the per-share purchase amount is less than the per-share amount of capital) the entire amount received will be transfer income.

The amount deemed to be a dividend is subject to a withholding of 20.315% (15.315% for income tax and special income tax for reconstruction and 5% for resident tax) (There will be no special withholding of the 5% resident tax for non-residents with a permanent establishment in Japan). However, if the shareholder is considered a principal shareholder as defined in Order for Enforcement of the Act on Special Measures Concerning Taxation, the withholding is 20.42% (income tax and special income tax for reconstruction only). As a general rule, the amount after deducting the cost of acquiring the shares from the transfer income is subject to declared separate income taxes.

(ii)

For Tendering Shareholders who are non-residents without a permanent establishment in Japan

The amount deemed to be a dividend will be subject to withholding of 15.315% (income tax and special income tax for reconstruction only). If the shareholder is considered a principal shareholder, the withholding will be 20.42% (income tax and special income tax for reconstruction only). As a general rule, income arising from the transfer will not be subject to taxation.

(b)

For corporate shareholders, when the amount of money received for accepting the tender offer exceeds the amount of the portion of the Company’s capital (or for a consolidated corporation, its consolidated individual stated capital) attributable to the shares that are the basis for that payment, the amount of this excess will be deemed a dividend. As a general rule, the portion deemed to be a dividend is subject to withholding of 15.315% (income tax and special income tax for reconstruction only).

A foreign shareholder who wishes to receive an income tax reduction or exemption for such deemed dividends pursuant to an applicable tax treaty should submit the tax treaty application form with the tender offer application form when applying to the tender offer.
