About 260 million personal records exposed in Japan in just over six months

Japan's Personal Information Protection Commission reported 2,094 cases of unauthorized access to personal data between April 1 and October 16, 2026, exposing about 260 million person-times of personal information — roughly twice Japan's population. Six of the incidents each exposed more than 10 million person-times. The sheer scale matters because it points to systemic exposure across many organizations, not a single isolated breach.
