Family membership

Dependent certification procedures are required when there is a change in dependents—for example, adding a family member as a dependent due to marriage or childbirth, or removing a dependent due to employment, death, or living separately. Note that those aged 75 or older who are enrolled in the Medical Care System for the Advanced Elderly cannot be dependents under the Health Insurance Association.
To be certified as a dependent, a family member must meet certain conditions regarding the scope of family and income.

As of April 1, 2020, a domestic residency requirement has been added to the dependent eligibility criteria. See here for details.

* Members who joined the Association after leaving employment (those with codes 457 or 459) are requested to contact the Health Insurance Association with any questions.

Notes	For dependent certification, various documents are required to verify the status of the person to be certified as a dependent. In principle, the dependent certification date is the date of the decision by the Health Insurance Association. Enter the relationship shown on the family register in the relationship field ⑪ on the Dependent (Change) Notice. If the actual place of residence differs from the address on the certificate of residence, submit an address change notification to report the current residence.

Points to note when naming a family member living separately as a dependent

* Excluding cases of unaccompanied job postings

To name a family member living separately as a dependent, it must be demonstrated that the family member's livelihood is continuously supported by the insured person. The proof of this financial support relationship must be something that can be publicly verified by a third party and clearly shows its continuity. Therefore, handing cash to the dependent in person is not acceptable. Please provide copies of bank remittance records or bank passbook pages to demonstrate the following items:

1.	Monthly remittance of a certain amount (at least 1/12 of the dependent's annual income) The annual remittance amount is no more than one-half of the insured person's annual income.
2.	Please send the above proof of monthly remittance records for three months to the Health Insurance Association. If you are starting remittances now, attach the above proof of one month's remittance record to this application and send it to the Health Insurance Association. The remaining two months' remittance records should be sent after the remittances have been made, after two months.
3.	Remittance records must clearly show the names of the remitting party and recipient, the amounts remitted, and remittance dates.
4.	To confirm that remittances are being made continuously, you may be asked to provide supporting documents (proof of remittance), so please keep them readily available at any time.
5.	The remittance amount must be equal to or more than the dependent's income and, in principle, at least the standard cost of living set for the prefecture capital city.
