That's 2 different subjects.
My Number Card, well, if you have one, currently I would NOT link it to your bank account. The local govt. were giving 20000 yen coupons if you did. I said screw it. To complicated for me.
Your NIC is issued in July every year. I don't see how it has anything to do with MY Number card.
Did you get the new card Yet? If not go to the city office that handles such affairs.
