Approximately 520,000 items of LINE user information are believed to have been leaked, and the government's Personal Information Protection Commission has ordered the operating company LINE Yahoo to make improvements, citing insufficient measures to protect the information. I have made the required recommendations.

LINE Yahoo has revealed that approximately 520,000 LINE user information and other information is suspected to have been leaked since November last year due to a cyber attack involving a South Korean IT company with which it has an indirect capital relationship. The Personal Information Protection Commission has investigated the actual situation.



As a result of the investigation, it was confirmed that despite LINE Yahoo sharing a system that accesses personal information with a Korean company, there were insufficient measures to protect the information. .



Similarly, three years ago, problems related to the management of personal information came to light, but appropriate measures were not taken even after that.

For this reason, on the 28th, the Personal Information Protection Commission called on LINE Yahoo's President Tsuyoshi Idezawa and made recommendations for improvements.



In March, LINE Yahoo received administrative guidance from the Ministry of Internal Affairs and Communications to prevent recurrence.

LINE Yahoo President: “We want to move forward with countermeasures quickly.”

After receiving the recommendation from the Personal Information Protection Commission, LINE Yahoo President Tsuyoshi Idezawa told reporters, ``I sincerely apologize for the inconvenience caused to many users and everyone involved. I would like to move forward with countermeasures quickly.''



The Ministry of Internal Affairs and Communications issued administrative guidance to LINE Yahoo on March 5, including its management structure, including its capital relationship with Naver, a Korean IT company that invests in LINE Yahoo's parent company along with Softbank. We are asking for your consideration to reconsider.



President Idezawa was asked by reporters whether he would proceed with a review of the capital relationship, saying, ``We take it seriously, and we are currently in discussions with the parent company.It is not something that we, as a subsidiary, can decide. I think we should first have a thorough discussion and then a direction will emerge.At this point, I can't give you a clear answer.''
