On November 6, prefectures and designated cities nationwide announced the temporary suspension of the official lottery website and app. This action was taken after user passwords were unintentionally changed, and unauthorized logins by third parties were confirmed on some accounts. The recovery timeline remains undetermined.
Member information may have been viewed by third parties. However, there are no signs of intrusion into the servers or databases, and no member data leaks have been confirmed. It is suspected that combinations of email addresses and passwords obtained externally were used, and users who reuse the same credentials across multiple services are urged to change their passwords.
According to an additional announcement on November 9, nationwide lottery retailers, financial institution sales websites, and ATM lottery services remain available as usual. The types of lottery tickets offered vary by purchase location. The operator stated that updates on the recovery status will be provided through official announcements and urged users not to enter their IDs or passwords on emails or websites impersonating the service.
