I would like to check the amount of National Pension Insurance premiums I paid for the year-end adjustment and tax return.

You can check the payment amount of the National Pension premium at the Fuchu Pension Office.
In addition, for those who have paid national pension insurance premiums, the Japan Pension Service will send a "social insurance premium (national pension premium) deduction certificate" such as a postcard.

Those who paid insurance premiums between January 1st and September 30th of this year.
In addition, description contents of certificate are amount of payment of premium and expected payment amount when payment is expected by the end of the year.

Those who paid premiums for the first time between October 1st and December 31st.

You can receive the deduction certificate by postcard, etc., or electronically.
Electronic data can be received at Mynaportal and used for final tax returns using e-Tax.
For details, please check the Japan Pension Service website (external link) .
