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.
