I have received a My Number. At what sorts of times is this used?

Every resident of Japan has a 12 digit personalized My Number. It is used for various procedures, including pension, taxes, and medical care. Even as a foreign national, if you have a certification of residence in Japan, you will have a My Number issued to you.

Various information about you can be learned through this number. It is a very important number, and if it is not clear what someone needs it for, you should not teach it to someone else. The card with your My Number written on it is also precious, so do not lose it.
