  • •The breach exposed personal data of 6.62 million accounts, including identification documents.

A group of over 100,000 customers is set to file a lawsuit against Park24 Co., the operator of the Times Car vehicle-sharing service, following a significant data breach. The breach, disclosed in late September 2026, compromised personal information from 6.62 million accounts due to unauthorized access to the company's web system. Among the leaked data are 1.46 million images of users' identification documents, including driver's licenses. The affected customers are seeking damages of 30,000 to 50,000 yen each for emotional distress. Park24 has offered a consolation payment of 3,000 yen per person but has not commented on the impending lawsuit. The legal action is expected to be filed by the end of the year, as the lawyer, Yuki Makino, aims to hold the company accountable for its handling of personal information protection.
