Notice on Schedule for Delisting American Depositary Shares from New York Stock Exchange

KONAMI CORPORATION (the Company) hereby announces, in connection with its announcement on November 6, 2014 relating to its intention to apply for voluntary delisting of its American Depositary Shares (ADSs) from the NYSE, that the Company has notified the New York Stock Exchange (the NYSE) on April 1, 2015 (Eastern Standard Time in the U.S.) that the Company will apply for voluntary delisting of its ADSs from the NYSE.

1. Reasons for Delisting

The Company listed its ADSs on the NYSE in September 2002 mainly to diversify its opportunities for fund-raising and to raise the visibility of the KONAMI brand. Since then, the Company has made efforts to enhance disclosures for shareholders and investors with the goal of deepening their understanding of the Company, in addition to complying with the disclosure requirements of U.S. securities laws and regulations, providing consolidated financial statements in accordance with accounting principles generally accepted in the United States (U.S. GAAP), and establishing internal controls in accordance with the Sarbanes-Oxley Act of 2002.

Meanwhile, the external environment has significantly changed as indicated by the increases in trading volume of Japanese stocks through stock exchanges in Japan by overseas investors due to the internationalization of the Japanese financial and capital markets, as well as the narrowing of the gap between U.S. and Japanese disclosure standards with respect to financial reporting due to a series of amendments to Japanese laws and regulations and accounting standards.

While the Company believes the initial objectives of the U.S. ADS listing were mainly achieved, it has judged that the continued listing on the NYSE is not economically justified, taking into account the market changes as stated above and the fact that the trading volume of its ADSs on the NYSE accounts for only a small fraction of the total trading volume of its shares. Therefore, the Company has decided to apply for voluntary delisting of its ADSs from the NYSE and for termination of registration of its ADSs with the U.S. Securities and Exchange Commission (the SEC) under the Exchange Act.

2. Stock Exchanges on which the Company Will Maintain its Listings

The Company will maintain its listings on the Tokyo Stock Exchange and the London Stock Exchange.

3. Delisting schedule (Eastern Standard Time in the U.S.)

April 1, 2015 The Company provided the NYSE with a written pre-notice of the delisting application April 13, 2015 The Company to file Form 25 with the SEC for delisting from the NYSE and deregistration with the SEC April 24, 2015 Delisting to become effective The Company to file Form 15F with the SEC to terminate its reporting obligations under the Exchange Act July 2015 Deregistration with the SEC to become effective Termination of the Companys reporting obligations under the Exchange Act to become effective

Note: The schedule provided above, including the anticipated effective dates, may be delayed if the SEC objects or requests an extended review or for other reasons.

4. Future Plans

After the delisting of its ADSs from the NYSE, the Company intends to maintain its American Depositary Receipt Program in the U.S., and therefore anticipates that its ADSs will continue to be traded in the U.S. on the over-the-counter market.

While the Companys reporting obligations under the Exchange Act (including the obligation to file annual reports on Form 20-F) will be terminated, the Company will continue to disclose financial statements and other information, in English, on its website to ensure that its overseas shareholders and investors will continue to have appropriate information about the Company.
