Section 2 Insured Period
第二節 被保険者期間
第十九条
When an insured period is calculated, this is done in months; the months from that in which a person acquires the status of an insured to the month preceding that in which the person forfeits that status are used to calculate it.
被保険者期間を計算する場合には、月によるものとし、被保険者の資格を取得した月からその資格を喪失した月の前月までをこれに算入する。
If, in the same month that a person has acquired the status of an insured, the person forfeits that status, that month is calculated as a one-month long insured period; provided, however, that this does not apply if the person acquires the status of an insured or an insured under a National Pension (excluding a category II insured specified in Article 7, paragraph (1) item (ii) of the National Pension Act) again in that month.
被保険者の資格を取得した月にその資格を喪失したときは、その月を一箇月として被保険者期間に算入する。ただし、その月に更に被保険者又は国民年金の被保険者（国民年金法第七条第一項第二号に規定する第二号被保険者を除く。）の資格を取得したときは、この限りでない。
For a person who has acquired the status of an insured again after having forfeited that status, the previous and subsequent insured periods are added up.
被保険者の資格を喪失した後、更にその資格を取得した者については、前後の被保険者期間を合算する。
The provisions of the preceding three paragraphs apply for each insured category.
Notwithstanding the provisions of paragraph (2) that were to have been applied pursuant to the provisions of the preceding paragraph, if a person has undergone a change of insured categories in the same month, that month is deemed to be a month in which the insured was under the insured category from after the change (if the insured has undergone a change of insured categories twice or more in the same month, that month is deemed to be a month in which the insured was under the last of those insured categories).
