If Aichi Prefecture had your data

  1. Look for Aichi Prefecture’s own notice or letter: it should say what of yours was involved. Keep it.
  2. Expect scams that use your details: calls, texts or emails pretending to be Aichi Prefecture, your bank or the police. Never give codes or passwords, never approve a sign-in you did not start, never move money.

One email to confirm first. We use your address only for this alert, and one click deletes it.
