China has experienced its largest-ever personal data breach, with approximately 4 billion records leaked, including information from major platforms such as WeChat and Alipay. This incident marks the biggest single personal data leak in history. In Japan, personal data leaks have also surged, reaching a record 21,000 cases in fiscal year 2024, effectively doubling from previous years. Among notable breaches in Japan, Sompo Japan Insurance reported a potential leak of up to 17.5 million customer records due to unauthorized access to its internal systems in mid-April 2025. The leaked data reportedly includes customers' names, addresses, and birthdates, although no misuse has been confirmed so far. Additionally, SoftBank disclosed that around 140,000 personal information records were leaked from an outsourcing company after a former employee illicitly removed customer data via USB in December 2024. These incidents highlight ongoing cybersecurity challenges across East Asia involving both private sector companies and digital platforms.
