A person who was an insured person of the insurance for specially-insured day laborers with the government as the insurer prescribed in Article 123, paragraph (1) of the Health Insurance Act on the day before the date of enforcement of the provisions of Article 4 is to become, on the date of enforcement of the provisions of Article 4, an insured person of the insurance for specially-insured day laborers with JHIA as the insurer under Article 123, paragraph (1) of the Health Insurance Act as Amended in October 2008.

①Insurance benefits paid by the Director-General of the Social Insurance Agency pursuant to the provisions of the Health Insurance Act before the date of enforcement of the provisions of Article 4 are deemed to be insurance benefits paid by JHIA pursuant to the corresponding provisions of that Act.

②Of the insurance benefits under the provisions of the Health Insurance Act for which the grounds for benefits arose before the date of enforcement of the provisions of Article 4, those not yet paid on that date are to be paid by JHIA.

With regard to the collection of insurance premiums for former government-managed health insurance and for the insurance for specially-insured day laborers with the government as the insurer, for which grounds for collection arose before the date of enforcement of the provisions of Article 4, and of other amounts to be collected on or after that date pursuant to the provisions of the Health Insurance Act Before the October 2008 Amendment, the collection of amounts pertaining to insured persons with optional and continued coverage and of amounts to be collected prescribed in Chapter IV of the Health Insurance Act (including the delinquent charges prescribed in Article 181, paragraph (1) of that Act) is to be carried out by JHIA, and the collection of all other amounts is to be carried out by the Minister of Health, Labour and Welfare.

With regard to litigation cases or non-contentious cases concerning the business of JHIA prescribed in Article 7-2, paragraphs (2) and (3) of the Health Insurance Act as Amended in October 2008 that are pending at the time of JHIA's establishment and that JHIA takes over, JHIA is deemed, as provided by Cabinet Order, to be the state or the administrative agency prescribed in the Act on the Authority of the Minister of Justice over Suits Relating to the Interests of the State (Act No. 194 of 1947), and that Act applies.

With regard to a person who, at the time of enforcement of the provisions of Article 4, is actually using the words "Japan Health Insurance Association" in its name, the provisions of Article 7-8 of the Health Insurance Act as Amended in October 2008 do not apply for six months after the enforcement of the provisions of Article 4.

②Until JHIA determines the insurance premium rate for each prefecture, the general insurance premium rate of former government-managed health insurance on the day before the date of enforcement of the provisions of Article 4 is used for the insurance premiums of insured persons of the health insurance administered by JHIA.

③Until JHIA determines the insurance premium rate for each prefecture, the average insurance premium rate prescribed in Article 168, paragraph (1), item (i), (a) of the Health Insurance Act as Amended in October 2008 is the general insurance premium rate of former government-managed health insurance on the day before the date of enforcement of the provisions of Article 4.

With regard to the first determination of the insurance premium rate for each prefecture after the establishment of JHIA, the provisions of Article 160, paragraphs (6) through (8) of the Health Insurance Act as Amended in October 2008 apply mutatis mutandis. In this case, the phrase "that prefecture" in paragraph (6) of that Article is deemed to be replaced with "each prefecture", and the phrase "Other than when being asked for an opinion referred to in the preceding paragraph, when the chief of a branch office finds it necessary to change the insurance premium rate for a prefecture" in paragraph (7) of that Article is deemed to be replaced with "When being asked for an opinion referred to in the preceding paragraph".

Where, among the insurance premium rates for each prefecture calculated pursuant to Article 160, paragraph (3) of the Health Insurance Act as Amended in October 2008, there are any for which the difference from the general insurance premium rate of former government-managed health insurance on the day before the date of enforcement of the provisions of Article 4 exceeds the standard specified by Cabinet Order, notwithstanding that paragraph, JHIA is to, from the day of its establishment and only until the date specified by Cabinet Order within a period ending March 31, 2024, taking into account the status of the efforts of each of its branches (meaning the branches prescribed in Article 160, paragraph (1) of the Health Insurance Act) concerning the maintenance and promotion of the health of insured persons and their dependents and the optimization of expenses required for medical care, adjust the insurance premium rates for each prefecture as provided by Cabinet Order and, following discussion at the management board, determine insurance premium rates for each prefecture that differ from the insurance premium rates for each prefecture so calculated.
