I am paying National Pension Plan (Kokumin Nenkin) premiums, but Address has changed.

If the first insured person is transferred to Address, the insured person whose My Number and Basic Pension Number are linked, in principle, notification of changes to Address is not required. However, procedures may be required for moving from overseas or moving overseas. For details, please contact the ward office National Pension Plan Section.
You can continue to use your National Pension Plan (Kokumin Nenkin) insurance payment slip after moving.
