Japan is finally moving some of its government services online – and My Number is central to the big plan. What exactly is it? And why do you need the plastic My Number card? 

What is My Number?

My Number was introduced in 2016 in order to streamline government services related to taxes, social security and disaster response. The number of organizations entitled to use your My Number is strictly limited by law to national and local administrative organs and select private entities.

You will need to present your My Number to:

– do your taxes

– open a bank account (especially if you plan to remit money abroad)

– get hired by a company in Japan

– confirm your pension qualification and to receive pensions payment

– receive unemployment insurance

– take advantage of services offered by Hello Work

– receive welfare benefits and insurance premiums

– collect medical insurance premiums

– receive funding for rebuilding the livelihood of disaster victims

– sign up for insurance

What is My Number Card?

My Number card is, as the name suggests, a card with your My Number (an individual identification number) written on it. There are two types: the My Number notification card and a plastic My Number IC card.

If you only need to know your My Number, then the paper card should be enough for you.
But if you want to use the additional functions of the My Number card, then you will need the plastic version.

Every resident of Japan will receive a paper My Number notification card via mail in the first 2-3 weeks of their stay in Japan. If you want a plastic card, you will have to apply for it at your local ward/city office (it usually takes about 1 month).

The plastic card is valid 10 years for Japanese nationals and foreign permanent residents, but the electronic certificate is only valid 5 years. In case of other mid- and long-term foreign residents, the card’s expiration date is the same as the expiration date of the residence card.
You will be notified when it’s time to renew the certificate or card. If you have the application form ID or a QR code on the notification letter, you can apply online. If not, you will need to visit the city office. In any case, renewal of the card and certificates will be free of charge.

Any changes to your name, address or the expiration date of your residence card will be registered on the front of the card. If there is no more space, you will have to get a new card.

The data from the front of the card is also stored in the chip.

Thanks to the chip, if you set up 2 passwords for your card, you will be able to:

1) use e-Tax to do your taxes online

2) print out various documents and certificates from city office at the convenience store

The card will start functioning as a health insurance card from 2021. There are also plans to make the login via the electronic certificate option available to some private sector companies.
