• Contents: As announced yesterday, the system used to send emergency alert emails (Area Mail) is currently unavailable, so we are still unable to send emergency alert emails (Area Mail) in Minato Ward.
  *Emergency Alert Messages (Area Mail) are a service that simultaneously sends evacuation information and other alerts to the cell phones and smartphones of people in designated areas during a disaster.
  This situation stems from the fact that “Arcadia Co., Ltd.,” the company responsible for operating the Emergency Alert Service (Area Mail), detected unauthorized access and shut down the system on Tuesday, October 13.
  The operating company is currently investigating the extent of the damage.
  Please note that the Emergency Alert Email (Area Mail) distribution system used by Minato Ward does not store any personal information; therefore, there is no impact on ward residents.
  We apologize for the inconvenience and concern this has caused our users.
  Minato Ward’s disaster prevention information emails, website, disaster prevention app, public address system, and official social media accounts are operated by systems separate from the affected system. These services remain available as usual, so please check these channels for the latest information in the event of a disaster. We will issue another announcement when the distribution of Emergency Alert Emails (Area Mail) resumes.
