第十条（国民年金任意加入期間の合算対象期間算入に関する経過措置）
The provisions of Article 7, paragraph (1) of the Supplementary Provisions of the National Pension Act after the revision by the provisions of Article 1 (or, after the revision by the provisions of Article 2, Article 9, paragraph (1) of the Supplementary Provisions of the National Pension Act after the revision by the provisions of that Article) do not apply to the period during which a person was an insured person under the provisions of Article 5, paragraph (1) of the Supplementary Provisions of the National Pension Act, for a person who has, as of the day preceding the item (iv) effective date, such a period during which the person was an insured person (excluding a premium-paid period prescribed in Article 5, paragraph (2) of the National Pension Act and a period during which the person was 60 years of age or older; the same applies hereinafter in this paragraph).
第一条の規定による改正後の国民年金法附則第七条第一項（第二条の規定による改正後にあっては、同条の規定による改正後の国民年金法附則第九条第一項）の規定は、第四号施行日の前日において国民年金法附則第五条第一項の規定による被保険者であった期間（国民年金法第五条第二項に規定する保険料納付済期間及び六十歳以上であった期間を除く。以下この項において同じ。）を有する者に係る当該被保険者であった期間については、適用しない。
The period during which a person was an insured person prescribed in the preceding paragraph is, in the case of applying the provisions of Article 7, paragraph (1) and Article 9, paragraph (1) of the Supplementary Provisions of the National Pension Act (or, after the revision by the provisions of Article 2, in the case of applying the provisions of Article 9, paragraph (1) of the Supplementary Provisions of the National Pension Act after the revision by the provisions of that Article), included, as of the item (iv) effective date, in the credited period prescribed in Article 7, paragraph (1) of the Supplementary Provisions of the National Pension Act after the revision by the provisions of Article 1 (or, after the revision by the provisions of Article 2, Article 9, paragraph (1) of the Supplementary Provisions of the National Pension Act after the revision by the provisions of that Article) (hereinafter referred to as the "credited period").
前項に規定する被保険者であった期間は、国民年金法附則第七条第一項及び第九条第一項の規定を適用する場合（第二条の規定による改正後にあっては、同条の規定による改正後の国民年金法附則第九条第一項の規定を適用する場合）にあっては、第四号施行日において、第一条の規定による改正後の国民年金法附則第七条第一項（第二条の規定による改正後にあっては、同条の規定による改正後の国民年金法附則第九条第一項）に規定する合算対象期間（以下「合算対象期間」という。）に算入する。
The calculation of the period included in the credited period pursuant to the provisions of the preceding paragraph is governed by the example of the provisions of Article 11 of the National Pension Act.
With regard to the application of the provisions of Article 18 of the Supplementary Provisions of the 1985 National Pension Amendment Act to a person who has a period included in the credited period pursuant to the provisions of paragraph (2), the phrase "the insured period of the National Pension on and after that day" in paragraph (1) of that Article is deemed to be replaced with "the period included, on and after that day, in the credited period pursuant to the provisions of Article 10, paragraph (2) of the Supplementary Provisions of the Act Partially Amending the National Pension Act, etc. to Strengthen, etc. the Financial Basis and Minimum Guarantee Function of the Public Pension System (Act No. 62 of 2012)", and the phrase "that Act" is deemed to be replaced with "the National Pension Act".
第二項の規定により合算対象期間に算入された期間を有する者に対する昭和六十年国民年金等改正法附則第十八条の規定の適用については、同条第一項中「同日以後の国民年金の被保険者期間」とあるのは「同日以後に公的年金制度の財政基盤及び最低保障機能の強化等のための国民年金法等の一部を改正する法律（平成二十四年法律第六十二号）附則第十条第二項の規定により合算対象期間に算入された期間」と、「同法」とあるのは「国民年金法」とする。
