Notification of Stock Split and Adoption of Tangen Share Unit System

In a meeting of the Board of Directors held today, Yahoo Japan Corporation decided to implement a stock split and adopt the Tangen share unit system. The stock split and adoption of the Tangen share unit system are contingent on the approval of partial revisions of the Company's articles of incorporation at the 18th ordinary shareholders' meeting scheduled to be held on June 20, 2013. Details are as follows.
I. Purpose behind Stock Split and Adoption of Tangen Share Unit System
The Company has decided to contribute to the greater convenience and liquidity of the stock market on which its shares are listed by implementing a stock split (100 for 1 stock split) and adopting the Tangen share unit system. This decision is in accordance with the Action Plan for the Consolidation of Trading Units announced by Japanese stock exchanges in November 2007. Please note that the stock split and adoption of the Tangen share unit system will not effect any actual change in the investment unit.
II. Summary of Stock Split
1. Stock split method
Using September 30, 2013 (Mon.) as the record date, shareholders noted in the final shareholders record on that date shall be issued 99 additional shares for each share owned (100 for 1 stock split).

Total issued shares will be the final number of total issued shares at the end of
September 30, 2013 (Mon.) multiplied by 99. Using the total issued shares on April
