Scenes of My Number Card use in emergencies

Last Updated:

We are working to improve the convenience of users by expanding the use of My Number Card even during emergencies.
The following are some emergency situations in which the My Number Card can be used.

Medical treatment

Here are some examples of how to use the My Number Card when you need medical care.
In addition, medical care needs to be prepared at all times. Please refer to use of My Number Card as a Health Insurance Certificate for details such as obtaining a My Number Card and registering for the first time use of your health insurance card.

At the time of emergency transport: Facilitation of emergency activities

The use of My Number Card as a Health Insurance Certificate makes it possible for ambulance personnel to view consultation history, medical information, drug information, and other information about patients in the My Number Card, even if the patients themselves are unable to explain their consultation history or the drugs they are taking at the time of emergency transport. This leads to the following smooth emergency response activities.

  • Reduce the burden on patients suffering from illnesses or injuries to explain their condition to paramedics by using My Number Card health insurance cards
  • Paramedics obtain accurate information on patients from the My Number Card and smoothly select hospitals to transport them to

In fiscal 2026, 712 fire defense headquarters (approximately 99% of fire defense headquarters, excluding remote islands, etc.) and 5,417 units (approximately 97% of ambulance teams) are using this system.
Please check the following for examples of initiatives.

Emergency surgery or hospitalization: No need to pay high medical care cost exceeding the maximum copayment amount

Even if you have to pay a large amount of medical expenses, by using My Number Card as your health insurance card, you do not have to temporarily pay the high medical expenses at the reception desk of medical institutions or pharmacies, nor do you have to go through the paperwork application procedures at the government office in advance.

The maximum amount of out-of-pocket expenses is determined by the High-Cost Medical Care Benefit Program. The high medical care cost Program is a program to provide the excess amount when the medical expenses paid at medical institutions or pharmacies exceed the maximum amount in a month (calendar month: from the 1st to the last day) so that the household burden of medical expenses will not be heavy. The maximum amount is determined according to age and income, and a system to further reduce the burden has also been established by satisfying several conditions. For details, please check with the for those who will use the High-Cost Medical Care Benefit Program (Ministry of Health, Labor and Welfare).

At the time of evacuation: Sharing medical and drug histories, etc.

The City of Mynaportal is conducting a demonstration project to ensure that medical care can be received safely and securely even during evacuation, including the ability to share past medical care and drug information, medicines that are usually taken, and specific medical examinations with doctors in the evacuation shelter.

Please check the following for examples of initiatives.

Disaster Response

We are also promoting efforts to improve convenience through My Number Card in each area of disaster response.

In times of emergency: evacuation shelter entering and leaving and material support

Targeting refugee support services (evacuation shelter management services, etc.) that occur during disasters, we are conducting surveys and research on appropriate support by improving services using digital technology and understanding victim information.
