How to use

It’s very easy to use.  At medical institutions and pharmacies that have an online system, you can take  medical examination without bringing your health insurance card if you bring your Individual Number Card to the counter.  Enter face recognition or PIN at the counter. At medical institutions and pharmacies that do not have an online system, you still need to show your health insurance card at the counter. Ask your medical institution directly or see the in-hospital poster to see if it is available.

About 8% of all medical institutions and pharmacies have introduced the online system.  There are still few.

[Three services that can be used with My Number Card] I will explain how to make My Number Card.


You can get a medical examination without waiting for the issuance of your health insurance card.

In Japan, when you change jobs or retire, you must return your health insurance card to the insurer (company or local government) and have your new employer or local government issue a new health insurance card again.  However, if you have registered your Individual Number Card as a health insurance card, you will be able to receive a medical examination as soon as the insurer’s procedure is completed without waiting for the issuance of a new insurance card. In the past, it took about 10 days to a month to issue a health insurance card, and during that time you had to pay the full amount of medical expenses.  (70% of medical expenses will be refunded after the health insurance card is issued)

There is no need to re-register

You only need to register once, and you do not need to re-register even if you change jobs or retire.  However, you still need to notify the insurer of your enrollment.  In the case of a company that is a member of the health and health association, the company will handle the procedure for joining, but if you are a member of the local health insurance (National Health Insurance), go to the local government office by yourself. , Let’s go through the procedure.

I know this if off topic but I’m looking into starting my own blog and was wondering what all is needed to get set up? I’m assuming having a blog like yours would cost a pretty penny? I’m not very internet smart so I’m not 100 sure. Any recommendations or advice would be greatly appreciated. Many thanks


In the case of Japan, you can run a blog if you have a personal computer and a monthly server fee. The server fee is about 1000 yen a month.
