The My Number System in Japan and how it affects non-Japanese
Starting in October of 2015, every citizen in Japan received a notification by mail (by “notification card”) regarding their 12-digit Social Security and Tax Number (also called Individual Number or “My Number”). Information about this new system has been brought up frequently across various media platforms in Japan. We would like to provide guidance, especially for mid and long term foreign residents in Japan, regarding the “My Number” system.
About Foreign Residents
A “My Number” will be issued to all registered residents who have a residential record at a municipal office. Mid- to long-term foreign residents (foreigners who have the legal status of residing in Japan for more than 3 months under the Immigration Control Act) and Special Permanent Residents are considered registered residents, and as such will also receive their Individual “My Numbers”.
What is the My Number System?
“My Number” System is the nickname for the “Social Security and Tax Number System”, which provides one unique number (12 digit numerical number) to all registered residents in Japan. The number is able to link and put together personal information dispersed across different multiple agencies under the name of the person it belongs to. This means the System serves as a social infrastructure to improve the efficiency and transparency of the social security and tax systems. In turn, bringing greater convenience to public services such as on-line applications for personal information and various administrative procedures while aiming to create a fair and just society.
About the notification card and Individual Number Card
What is a Notification Card?
A notification card is a document sent to every resident of Japan to notify them of their “My Number” (the Individual Number). It will be sent using recorded delivery to the address appearing in your residential record (to the householder) to all residents. This includes foreigners starting from the beginning of October 2015 till approximately the end of November 2015.
From this point forward, all foreigners who entering Japan for a mid- to long-term stay, will receive a “My Number” (the Individual Number) on the day of or the day after their Basic Resident Registry is made, after submitting a Notification of Moving-in at their local municipal office. They can confirm their “My Number” at the time of issuance. A notification card will still mailed to them in approximately two weeks regardless of having confirmed their “My Number” on the date of issuance or not.
Your “name,” “address,” “date of birth,” “sex,” and “My Number” (the Individual Number), etc., registered in the resident record of your municipality will be noted on the notification card.
※ You can use the notification card as a document to certify your “My Number” (the Individual Number) in various situations where you are required to present your “My Number” (the Individual Number) card. However you have to also present your driver’s license or passport as a proof of your identity in order to prevent the use of your “My Number” card by somebody else. (The actual Individual Number Card itself is proof of your identity and you don’t need any other proof).
※ Note: The notification card is a document that certifies the Individual Number. Please keep your notification card until you receive the actual Individual Number Card.
Obtaining a "My Number" Card
After you have gone to your local ward office to register your address, a “My Number” number will be created. If you would like to know the number you can ask the person helping you and they will write it down for you. After some time, a notification card will arrive at your home along with an application and an extra envelope. On the notification card will be your “My Number” information.
The application that came along with the notification card is for your “My Number” card. After you send in your application, you will receive another notification in the mail telling you that your “My Number” card is finished and ready to be picked up. Take a photo I.D. (driver’s license, passport, residence card) and your notification card with the “My Number” information on it to the ward office along with the notification postcard telling you that your card is ready.
If you have lost your application for your “My Number” card or are unable to find it, you can apply by mail or online.
For further details regarding the application method and how to receive the card, please see the web-page below:

About companies employing foreigners
After January 2016, the “My Number” will be listed on the withholding slip and various other payment records of salaried employee. As a result, administrative agencies will get to know more about the submission of tax returns and the tax payment situation of foreign employees. When they apply for Permission for Extension of Period of Stay or for permanent residency, but they are not fulfilling their tax obligations, it will be evaluated as a negative factor. Companies need to pay attention to this and instruct employees as necessary.
In addition, the payment situation of social insurance premiums will be confirmed automatically by administrative agencies. So taking this opportunity, it is particularly important for a company to instruct a foreigner hired in Japan about participation in social insurance and the payment of the premium and the (※) lump sum withdrawal payment system of the pension plan.
(About employees transferring from other countries, a company should follow the social security agreement with each country.)
A “My Number” issued to a foreign resident is also valid throughout his or her entire lifetime.
When a foreign resident with the status of mid-to-long term stay makes a simple departure (leaving Japan without obtaining a re-entry permit) to their own country, he or she shall return their notification card or Individual Number Card along with their residence card to each municipal office. Upon the return of your cards to the municipal office, another card listing your “My Number” will be issued to you for your records. If you come to stay in Japan again in the future as a mid- to long term resident, showing the aforementioned card, given to you for your records, will allow you to receive the same Individual Number Card that you previously had.
※What is the Lump-sum Withdrawal Payment System?
It is the system to refund money according to the premiums paid by a foreigner into a Japanese pension plan (such as National Pension Plan, welfare annuity, and mutual aid association pension) when going back to his or her own country after living in Japan for a short term (longer than six months). It is a system to prevent social security insurance premiums from not being refunded.
General matters that require attention in the handling of “My Number” in a company
When making a withholding slip and a payment record, a company is required to acquire the “My Number” of employees regardless of the type of employment or the length of employment, including part-time staff. Since short term employees such as part-time staff may leave a company suddenly, it is necessary to prepare for the paperwork for the procedures required for acquiring their “My Number” at the time of employment.
A company must specify, notify, and announce the purposes for which they intend to use an employee’s “My Number” when obtaining them. In addition, the usages of a “My Number” are limited as a general rule. Companies are only allowed to handle a “My Number” for use in documents designated in the law set forth by the government; such as a withholding slip or a payment record.
In other words, a company cannot use a “My Number” outside the scope of usage that has been designated by law. A company cannot irresponsibly provide Specific Personal Information (personal information that includes an Individual Number) to others or keep storing it. In order to acquire a “My Number” smoothly, a company should notify all the employees of its usage rules and restrictions.
A company also must take necessary measures to ensure the appropriate management of “My Numbers” when handling them. This includes the prevention of leaks, loss, and damage. If a company should have leaked out any “My Number” of its employees, the company will risk 3 of the following in general:
1. Criminal charges
2. Liability for damages
3. Accrual of the cost for responding to the administration
These repercussions seem to be considerably stricter in terms of laws than the risks associated with conventional handling of personal information. As described here for handling of a “My Number” in a company, extreme attention and strict management as well as the understanding of the employees are required.
