The benefits under this Act (hereinafter simply referred to as "benefits") are as follows.

The right to receive a benefit is decided by the Minister of Health, Labour and Welfare based on the claim of the person who holds that right (hereinafter referred to as a "person entitled to receive a benefit").

①When preparing the current state and outlook of finances under the provisions of Article 4-3, paragraph (1), the government is, if it is expected that the finances of the National Pension program will be unable to maintain their balance over the financial equilibrium period while holding the reserve fund (meaning the reserve fund of the National Pension Account of the Pension Special Account; the same applies in Chapter V) necessary to prevent a disruption in the payment of benefits at the end of the financial equilibrium period, to adjust the amount of benefits that are pensions (excluding the additional pension) (hereinafter in this paragraph referred to as the "benefit amount"), and is to specify by Cabinet Order the fiscal year in which the period for adjusting the benefit amount (hereinafter referred to as the "adjustment period") begins.

②When it is found, in the current state and outlook of finances, that the adjustment under the preceding paragraph is no longer necessary, the fiscal year in which the adjustment period ends is to be specified by Cabinet Order.

③When the government prepares the current state and outlook of finances during the adjustment period, it must also prepare the outlook for the fiscal year in which the adjustment period ends, and must make this public together with it.

①When deciding the right to receive a benefit that is a pension (hereinafter referred to as a "pension benefit"), or when revising the amount of a pension benefit, if a fraction of less than 50 sen arises in the amount of the pension benefit, it is to be rounded down, and if a fraction of 50 sen or more but less than 1 yen arises, it is to be rounded up to 1 yen.

②Beyond what is prescribed in the preceding paragraph, the treatment of a fraction of less than 1 yen that arises when calculating the amount of a pension benefit is specified by Cabinet Order.

①Payment of a pension benefit is to begin from the month following the month in which the day on which the grounds for payment arose falls, and is to end with the month in which the day on which the right was extinguished falls.

②When grounds for suspending the payment of a pension benefit arise, payment is suspended for the portion from the month following the month in which the day on which the grounds arose falls, through the month in which the day on which the grounds ceased to exist falls. However, if these days fall within the same month, payment is not suspended.

③A pension benefit is paid, in six installments each year, in February, April, June, August, October, and December, for the portion up to the month preceding each such month. However, a pension that should have been paid in the preceding payment month, or the pension for the installment in a case where the right has been extinguished or the payment of the pension has been suspended, is to be paid even in a month that is not a payment month.

①When a fraction of less than 1 yen arises in the amount paid under the provisions of paragraph (3) of the preceding Article, it is to be rounded down.

②The total of the amounts rounded down under the provisions of the preceding paragraph during the period from March each year to February of the following year (or, if a fraction of less than 1 yen arises in that total, the amount after that fraction is rounded down) is to be added to the pension amount for the payment month of that February.

If, where a vessel has sunk, capsized, been lost, or gone missing, it is unknown for three months whether a person who was actually on board the vessel at the time, or a person who was on board the vessel and went missing while the vessel was navigating, is alive or dead, or if the death of such a person becomes clear within three months but the time of death is unknown, then, for the purposes of applying the provisions concerning the payment of a benefit for which death is the ground for payment, that person is presumed to have died on the day on which the vessel sank, capsized, was lost, or went missing, or on the day on which the person went missing. The same applies where an aircraft has crashed, been lost, or gone missing, and it is unknown for three months whether a person who was actually on board the aircraft at the time, or a person who was on board the aircraft and went missing while the aircraft was navigating, is alive or dead, or where the death of such a person becomes clear within three months but the time of death is unknown.

For the purposes of applying the provisions concerning the payment of a benefit for which death is the ground for payment, relating to a person who is deemed to have died as a result of receiving an adjudication of disappearance, the term "date of death" in Article 37, Article 37-2, Article 49, paragraph (1), Article 52-2, paragraph (1), and Article 52-3, paragraph (1) is deemed to be replaced with "the day on which the person went missing", and the term "at the time of death" is deemed to be replaced with "at the time the person went missing". However, this does not apply to the application of these provisions relating to the familial relationship, age, and state of disability of a person entitled to receive a benefit, or of a person who is a requirement for the payment of a benefit or is the subject of an addition to its amount.

①Where a person entitled to receive a pension benefit has died, if there is a pension benefit that should have been paid to the deceased person but has not yet been paid to that person, the spouse, child, parent, grandchild, grandparent, or sibling of that person, or a relative within the third degree of kinship other than these persons, who shared living expenses with that person at the time of that person's death, may, in their own name, claim payment of that unpaid pension.

②In the case referred to in the preceding paragraph, if the deceased person was a person entitled to receive a survivors' basic pension, a child of the insured person or person who was an insured person that, at the time of that person's death, constituted a requirement for the payment of that survivors' basic pension or was the subject of an addition to its amount, is deemed to be a child as prescribed in that paragraph.

③In the case referred to in paragraph (1), if the deceased person entitled to receive a benefit had not claimed that pension before death, a person prescribed in that paragraph may, in their own name, claim that pension.

④The order of priority of persons entitled to receive an unpaid pension is specified by Cabinet Order.

⑤When there are two or more persons of the same order of priority who are entitled to receive an unpaid pension, a claim made by one of them is deemed to have been made by all of them for the full amount, and a payment made to one of them is deemed to have been made to all of them.

①A survivors' basic pension or a widow's pension is, while the person entitled to receive it is able to receive another pension benefit (excluding the additional pension) or an insurance benefit that is a pension under the Employees' Pension Insurance Act (excluding one paid on the same ground for payment as that pension benefit; the same applies hereinafter in this Article), suspended for that period. The same applies to the old-age basic pension, in a case where the person entitled to receive the old-age basic pension is able to receive another pension benefit (excluding the additional pension) or an insurance benefit that is a pension under that Act (excluding the survivors' employees' pension), and to the disability basic pension, in a case where the person entitled to receive the disability basic pension is able to receive another pension benefit (excluding the additional pension).

②A person entitled to receive a pension benefit whose payment is to be suspended under the provisions of the preceding paragraph may, notwithstanding the provisions of that paragraph, apply for the suspension of payment to be lifted. However, this does not apply where the suspension of payment of the other pension benefit or the insurance benefit that is a pension under the Employees' Pension Insurance Act prescribed in that paragraph relating to that person has been lifted under the main clause of this paragraph, the following paragraph, or a provision specified by Cabinet Order as equivalent to these under other laws and regulations.

③With respect to a pension benefit whose payment is to be suspended under the provisions of paragraph (1), if payment is made for the portion of the month in which the day on which the grounds for suspending payment arose falls, the application under the preceding paragraph relating to that pension benefit is deemed to have been made at the time those grounds arose.

④The application under paragraph (2) (including that application in a case where it is deemed, under the provisions of the preceding paragraph, to have been made) may be withdrawn at any time, with effect for the future.

①Payment of the full amount of a pension benefit (excluding a pension benefit whose payment is suspended in full under another provision of this Act or a provision of other laws and regulations) is suspended upon the request of the person entitled to receive it. However, if payment of part of the amount is suspended under another provision of this Act or a provision of other laws and regulations, payment of the amount of the part not suspended is suspended.

②With respect to a pension benefit whose payment of part of its amount is suspended as referred to in the proviso to the preceding paragraph, when the suspension of payment under another provision of this Act or a provision of other laws and regulations is lifted, payment of the full amount of the pension benefit referred to in the main clause of the preceding paragraph is suspended.

③The request under paragraph (1) may be withdrawn at any time, with effect for the future.

④A pension benefit whose payment is suspended under the provisions of paragraph (1) or paragraph (2) is, for the purposes of applying a provision of laws and regulations specified by Cabinet Order, deemed not to have had its payment suspended.

⑤The method of the suspension of payment under the provisions of paragraph (1), and other matters necessary for applying the provisions of the preceding paragraphs, are specified by Cabinet Order.

①Where the right of a person entitled to receive Pension B to receive it is extinguished because the person entitled to receive Pension B has acquired the right to receive Pension A, or where, for the same person, payment of Pension B is to be suspended and Pension A is to be paid, if payment of Pension B has been made for the portion from the month following the month in which the day on which the right to receive Pension B was extinguished, or the day on which the grounds for suspending payment of Pension B arose, falls, that paid Pension B is deemed to be a payment on account of Pension A.

②When, notwithstanding that grounds for suspending payment of a pension have arisen, the pension has been paid for the portion of the period for which it should have been suspended, the pension so paid may be deemed to be a payment on account of the pension that should be paid thereafter. The same applies to the portion that should have been reduced, of a disability basic pension or a survivors' basic pension, in a case where, notwithstanding that grounds have arisen for revising the disability basic pension or the survivors' basic pension by reducing it, the disability basic pension or the survivors' basic pension has been paid, for the portion from the month following the month in which the day on which those grounds arose falls, in the amount without the reduction.

③Where, for the same person, payment of an insurance benefit that is a pension under the Employees' Pension Insurance Act (limited to one paid by the Minister of Health, Labour and Welfare; the same applies hereinafter in this paragraph) is to be suspended and a pension benefit is to be paid, if payment of the insurance benefit that is a pension under that Act has been made for the portion from the month following the month in which the day on which the grounds for paying the pension benefit arose falls, the insurance benefit that is a pension under that Act so paid may be deemed to be a payment on account of the pension benefit.

Where, notwithstanding that the right to receive a pension benefit has been extinguished because the person entitled to receive the pension benefit has died, an erroneous payment of that pension benefit has been made for the portion from the month following the month in which the day of that death falls, if there is a pension benefit to be paid to a person who is to perform the obligation pertaining to the claim for repayment relating to that erroneous payment (hereinafter in this Article referred to as a "claim for repayment"), the amount of the payment of that pension benefit may be applied to the amount of the claim for repayment arising from that erroneous payment, as specified by Order of the Ministry of Health, Labour and Welfare.

①Where a disability or death, or an accident that was the direct cause thereof, has arisen from the act of a third party, if the government has made a benefit payment, the government acquires, to the extent of the value of that benefit, the right that the person entitled to receive the benefit holds against the third party to claim damages.

②In the case referred to in the preceding paragraph, if the person entitled to receive the benefit has received damages from the third party for the same cause, the government is relieved of its obligation to make the benefit payment, to the extent of that value.

When there is a person who has received a benefit by deception or other wrongful means, the Minister of Health, Labour and Welfare may collect from that person the whole or part of an amount equivalent to the amount received.

The right to receive a benefit may not be transferred, provided as security, or seized. However, this does not apply to a case where the right to receive an old-age basic pension or an additional pension is seized by a disposition for national tax arrears (including a disposition governed by the same rules).

Taxes and other public charges may not be imposed based on money received as a benefit. However, this does not apply to an old-age basic pension and an additional pension.

An old-age basic pension is paid to a person who has a premium-paid period or a premium exemption period (excluding one relating to a premium that a person has been made not required to pay under the provisions of Article 90-3, paragraph (1)), when that person reaches 65 years of age. However, this does not apply when the period obtained by combining that person's premium-paid period and premium exemption period is less than 10 years.

The amount of the old-age basic pension is the amount obtained by multiplying 780,900 yen by the revision rate (meaning the rate set under the provisions of paragraph (1) of the following Article and revised under the provisions of that Article (excluding paragraph (1)) through Article 27-5; the same applies hereinafter) (if a fraction of less than 50 yen arises in that amount, it is to be rounded down, and if a fraction of 50 yen or more but less than 100 yen arises, it is to be rounded up to 100 yen). However, when paid to a person whose number of months of premium-paid periods is less than 480, the amount is the amount obtained by multiplying that amount by the number obtained by dividing the number of months obtained by combining the numbers of months listed in the following items (480 being the maximum) by 480.

①The revision rate in fiscal year 2004 is 1.

②The revision rate is revised each fiscal year based on the rate obtained by multiplying the rate listed in item (i) (hereinafter referred to as the "price change rate") by the rates listed in item (ii) and item (iii) (hereinafter referred to as the "nominal net wage change rate"), and is applied to a benefit that is a pension from April of that fiscal year onward.

③The measures for revising the revision rate under the provisions of the preceding paragraph are specified by Cabinet Order.

①With respect to the revision of the revision rate that applies from and after the fiscal year in which April 1 of the year three years after the year in which the first day of the fiscal year in which the person entitled to receive the benefit reached 65 years of age falls, falls (referred to as the "base fiscal year" in Article 27-5, paragraph (1), item (ii) and paragraph (3), item (i)) (hereinafter referred to as the "revision rate from the base fiscal year"), the price change rate (or, when the price change rate exceeds the nominal net wage change rate, the nominal net wage change rate) is, notwithstanding the provisions of the preceding Article, taken as the basis.

②The measures for revising the revision rate from the base fiscal year under the provisions of the preceding paragraph are specified by Cabinet Order.

①With respect to the revision of the revision rate during the adjustment period, notwithstanding the provisions of the preceding two Articles, the rate obtained by multiplying the nominal net wage change rate by the rate obtained by multiplying the adjustment rate (meaning the rate obtained by multiplying the rate listed in item (i) by the rate listed in item (ii) (or, when that rate exceeds 1, 1); the same applies hereinafter) by the special adjustment rate for the fiscal year preceding that fiscal year (or, when that rate is less than 1, 1; referred to as the "calculated rate" in paragraph (3), item (ii)) is taken as the basis.

②With respect to the revision of the revision rate during the adjustment period in a case where the nominal net wage change rate is less than 1, notwithstanding the provisions of the preceding paragraph, the nominal net wage change rate is taken as the basis.

③The special adjustment rate in paragraph (1) means the rate set under the provisions of item (i) and revised under the provisions of item (ii).

④The measures for revising the revision rate under the provisions of the preceding three paragraphs are specified by Cabinet Order.

①With respect to the revision of the revision rate from the base fiscal year during the adjustment period, notwithstanding the provisions of the preceding Article, the rate obtained by multiplying the rate listed in item (i) by the rate listed in item (ii) (or, when that rate is less than 1, 1; referred to as the "calculated rate from the base fiscal year" in paragraph (3), item (i), (b)) is taken as the basis.

②With respect to the revision of the revision rate from the base fiscal year during the adjustment period in a case listed in the following items, notwithstanding the provisions of the preceding paragraph, the rate specified in the relevant item is taken as the basis.

③The special adjustment rate from the base fiscal year in paragraph (1) means the rate set under the provisions of item (i) and revised under the provisions of item (ii).

④The measures for revising the revision rate from the base fiscal year under the provisions of the preceding three paragraphs are specified by Cabinet Order.

①A person who has the right to receive an old-age basic pension and who has not claimed that old-age basic pension before reaching 66 years of age may make a request to the Minister of Health, Labour and Welfare to defer payment of that old-age basic pension. However, this does not apply where, when that person reached 65 years of age, the person was a person entitled to receive another benefit that is a pension (meaning another pension benefit (excluding the additional pension) or an insurance benefit that is a pension under the Employees' Pension Insurance Act (excluding one for which old age is the ground for payment); the same applies hereinafter in this Article), or where the person became a person entitled to receive another benefit that is a pension during the period from the day the person reached 65 years of age to the day the person reached 66 years of age.

③Payment of the old-age basic pension to a person who has made the request under paragraph (1) (including that request in a case where the request under paragraph (1) is deemed, under the provisions of paragraph (5), to have been made; the same applies in the following paragraph) is, notwithstanding the provisions of Article 18, paragraph (1), to begin from the month following the month in which the day of that request falls.

④The amount of the old-age basic pension paid to a person who has made the request under paragraph (1) is, notwithstanding the provisions of Article 27, the amount obtained by adding, to the amount specified in that Article, an amount specified by Cabinet Order.

⑤When a person who may make a request to defer payment of an old-age basic pension under the provisions of paragraph (1) claims that old-age basic pension after the day of reaching 70 years of age, and does not make the request under that paragraph at the time of that claim, the request under that paragraph is deemed to have been made on the day five years before the day of that claim. However, this does not apply where that person falls under any of the following items.

The right to receive an old-age basic pension is extinguished when the person entitled to receive it dies.

①A disability basic pension is paid to a person who has suffered an illness or been injured, and who, on the date of first receiving medical examination or treatment from a physician or dentist for that illness or injury and an illness resulting from it (hereinafter referred to as "injury or illness") (hereinafter referred to as the "date of first medical examination"), fell under any of the following items, when, on the day on which one year and six months have elapsed, calculated from that date of first medical examination (or, where that injury or illness was cured within that period, the day it was cured (including the day on which the symptoms became fixed and no further therapeutic effect could be expected); hereinafter referred to as the "disability recognition date"), that person is, because of that injury or illness, in a state of disability to the extent of falling under the disability grade prescribed in the following paragraph.
