Japanese energy giant loses customer data in security lapse
A storage drive containing private data of more than 10 million customers has gone missing from Kyushu Electric Power Co., Inc., exposing names, addresses, and other personal details.
How the loss occurred
The incident unfolded after a physical security breach at a facility operated by a Kyushu Electric Power subsidiary. An external storage drive—used to store customer information—was reported missing during a routine check, prompting the company to file an official disclosure with Japanese regulators.
What data was exposed
According to the company’s filing, the lost drive contained customer names, addresses, telephone numbers, and contract numbers. No payment or highly sensitive authentication data were included, Kyushu Electric stated. The company has not indicated whether the drive was encrypted or password-protected.
Next steps and regulatory response
Kyushu Electric has launched an internal investigation and notified the relevant Japanese authorities. It is also reviewing its data handling and storage procedures to prevent similar incidents in the future. While the company has not reported signs of misuse, customers whose data was exposed have been advised to monitor their accounts and report any suspicious activity.
