What is My Number Card?

My Number Card is a public card issued by the Japanese government.
Anyone who has a residence card in Japan can have it.
On the official website, it is called Individual number card in English.

My number will be assigned to all people living in Japan.
This My Number is mainly used for “social security,” “tax,” and “disaster countermeasures.”

Having my number card shortens administrative procedures. In addition, various certificates can be issued at convenience stores.
Details will be described later.

My number card can be used as a public ID card with a photo of your face.
There are few official ID cards with a face photo in Japan, and a typical one is a driver’s license.
My number card is good because it is easy to obtain unlike a driver’s license.

Use as a health insurance card

From March 2021, My Number Card can be used as a health insurance card.
To use it, you need to apply online in advance.

By using your My Number Card as your health insurance card, you do not have to pay or be charged a high medical fee of 100,000 yen or more.
Normally, if you are billed for medical expenses of 100,000 yen or more, you need to pay once and then receive a subsidy from the government.

I recommend that you register your health insurance card as there are other benefits as well.

It is difficult to go to the city hall during this time as most working people are busy.

The convenience store copier is equipped with a card reader for scanning My Number cards.
