Yahoo! JAPAN/DeNA deal

FOR IMMEDIATE RELEASE

Yahoo Japan Corporation (hereinafter, “Yahoo! JAPAN,” President and CEO: Masahiro Inoue) and DeNA Co., Ltd. (hereinafter, “DeNA,” Chief Executive Officer: Tomoko Namba) today agreed to enter a business tie-up in the field of social games.

Social games have enjoyed a worldwide surge in popularity in recent years. The Japanese market also has the potential for rapid growth, not only in the mobile arena but also on PCs. Accordingly, Yahoo! JAPAN and DeNA plan to launch a PC-based social game platform (tentatively named Yahoo! Mobage) this late summer. The two companies believe that combining the platform for Moba-ge-town, which currently has more than 18 million registered members, with Yahoo! JAPAN’s strength and ability to attract customers, plus the game development and operational expertise that DeNA has cultivated in the mobile arena, offer the opportunity for major synergies. Game developers’ development and roll-out of games that use the Mobage API should also help drive market expansion.

Yahoo! Mobage will provide a structure that enables the same games to be played both in PC and mobile environments. The new platform will also create a development and promotional environment that helps game developers roll out the same game for mobile terminals and PCs.
