Apologies for the malfunction in Yahoo! JAPAN ID information registration system of

Yahoo Japan Corporation, and notice on the resolution of the incident

We have discovered that, in our consolidated subsidiary, Yahoo Japan Corporation (hereafter "Yahoo Japan"), there was a malfunction in the information registration system of Yahoo! JAPAN ID (hereafter "ID"), which is used in its various services, and that registered ID information (name, address, telephone number, etc.) of some of its ID holders was erroneously reflected in ID information of others (maximum approx. 390,000 IDs).

We would like to express our sincerest apologies to the ID holders and to everyone concerned for the inconveniences and concerns that this may have caused. Please find the outline of this incident below.

Please note that emails are being sequentially sent to each of those whose registered ID information has been erroneously overwritten, and we are asking them to re-enter their ID information. Also, please note that the deletion of erroneously overwritten information has been completed.

1. Outline of incident

  1. Some of those who attempted to edit any of their registered ID information (name, address, telephone number, etc.) in between July 29 (Wed.) 14:06 and August 4 (Tue.) 23:50 ("ID Holders A"), did not have their revised information reflected in their own registered ID information. Instead, the information was erroneously reflected in the registered ID information of another ID holder ("ID Holders B").
    As a result, there is a possibility that the revised ID information of ID Holders A may have been browsed by ID Holders B, and that items or services ordered by ID Holders B may have been delivered, based on the erroneously overwritten information, to ID Holders A.
  2. In some ID Holders B who purchased items, concluded agreements, browsed their registered ID information in between July 29 (Wed.) 14:06 and August 4 (Tue.) 23:50, their registered ID information was overwritten by the information of ID Holders A.
