The Gifu center’s mail/web server was breached on 27 October. A 6 November report confirms leaked emails and other data for 3,058 people, with up to 8,074 potentially affected. These counts are not additive. [1] [2]

Affected material includes training/inquiry/service forms, newsletter registrations, and email bodies and attachments. Depending on the record, fields may include names, birth dates, gender, employer/contact details and medical-registration numbers; not every field applies to everyone. [2]

The website and mail were stopped and outside access blocked on 27 October. Compromised addresses were also used to attempt unauthorized registrations/applications at government sites, without confirmed resulting damage or misuse of the leaked data. Cause and scope remain under investigation. [2]
