Family membership
Health insurance provides insurance benefits not just to insured persons but also to their dependent family members. These family members are referred to as "dependents". Family members must meet certain conditions related to "residency in Japan," "the extent of the family relationship," and "income" before they are authorized as dependents.

Documents to attach for dependents without an address in Japan who qualify for exceptions from the domestic residency requirement
See here for details of the domestic residency requirement and the documents to attach for those who qualify for exceptions.
Documents to attach
- If it will take time to prepare documents to attach, submit at least the Dependent Notice (Notice of Change) and Survey form determining eligibility for dependent status within five business days after the date on which the family member became eligible for certification.
- Purposes of use
The Sony Health Insurance Society will review the attached documents to confirm the family member’s income, living conditions, and whether anyone else in the household can provide for him or her as a dependent. - Submit the originals of all documents unless the text explicitly states copies are acceptable. The review will not begin until all documents are received.
- Note that the documents submitted will not be returned. Make copies for you to keep before submitting, if necessary.
- In certain cases, the Society may check with the issuers of submitted documents to verify their content.
- Note that you may be asked to submit documents other than those listed above as needed for review purposes. No review may take place if you reject the request.
- Since these documents contain personal information, if you would prefer that staff responsible for health insurance at your employer not see such information, submit them in an envelope (provide the envelope yourself)
