The backup external storage media has disappeared from its storage location and has not been located as of now. The media includes customer names, supply location addresses, electricity consumption data, telephone numbers, and retail electricity provider names, potentially affecting up to 10.9 million accounts. While security measures were in place, it is believed that the lack of proper locking was a factor, and no actual leakage has been confirmed. Reports have been submitted to relevant authorities. Moving forward, efforts will focus on locating the media and implementing prevention measures.\n\n### Future Measures and Impact\nThe company will notify affected customers individually and review and implement management and prevention measures for external storage media. The direct impact on financial results is currently unclear; however, risks related to potential information leakage, as well as increased customer response workload, are concerns. Further disclosures or strengthened measures may be enacted depending on investigation outcomes.","jir_financial_highlights":"Unknown: Unknown (Unknown)","jir_category":"","jir_hashtags":"#KyushuElectricPower, #InformationLeakage, #JapanStocks","jir_key_figures":"Number of customer accounts: up to 10.9 million accounts\nDates of occurrence: April 27, 2026, and May 26, 2026\nTargeted information: customer names, supply location addresses, electricity usage data, phone numbers, retail electric provider names","jir_meta_title":"\u3010Kyushu Electric Power\u3011Customer Information Location Unknown | June 8, 2026","jir_meta_description":"An incident involving the unknown location of external storage media containing customer information at Kyushu Electric Power Transmission & Distribution has occurred.
