Muji's President Apologizes for Data Breach: Ryohin Keikaku president, Tomo Shimizu, held a press conference on November 12th to apologize for a major data breach affecting Muji's online store and app. The breach potentially exposed approximately 1.09 million credit card numbers, including full card details for some MUJI Card holders, and up to 27.26 million member information records.

Key issues highlighted during the press conference include:

Failure to delete unnecessary data: Credit card numbers were retained even after they were no longer needed for identification, and were stored without masking.
System vulnerabilities: The company acknowledged weaknesses in its system that allowed for the unauthorized access.
"Muji Week" sale timing: The president denied that the timing of the "Muji Week" sale influenced the decision on when to announce the breach.

The online store has been down since November 6th, with no immediate estimate for its restoration. The company is investigating the extent of the damage and will provide compensation to affected customers.
