Japan's Muji parent company Ryohin Kepenko held a press conference today after a large-scale personal information leak occurred. President Shimizu Satoshi publicly bowed and apologized, saying "I sincerely apologize for causing great concern and distress to everyone."

Ryohin Project announced that after the company system was hacked, the mailboxes and other information of up to 27.26 million members, including those who have withdrawn from membership, may have been leaked, and about 1.09 million credit card numbers were leaked. In addition, hackers also used passwords leaked from other services to try to log into member accounts in large numbers, resulting in the possible leakage of about 270,000 pieces of personal information.

The company admitted that the credit card numbers should have been replaced so that they could not be identified by third parties when they were being kept, but it was not actually done so. In addition, although internal regulations require that the data of those who have withdrawn from membership be deleted after a certain period of time, some of it has not been deleted.

Regarding the follow-up processing, Ryohin Keikai stated that it will strengthen system monitoring. For customers whose credit card numbers have been leaked, it will fully bear the card re-issuance fee. If actual damage is confirmed, compensation will be based on the content. As for the responsibility of the management team, Shimizu Satoshi said that it will first let the incident end, establish a trustworthy mechanism, and then hand it over to the board of directors for discussion.
