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.

  • In the case of finding employment, the date eligibility was obtained to receive coverage from other health insurance or the date employment was found
  • In the case of divorce, the date of divorce
  • In the case of starting to receive employment benefits, the starting date for receiving unemployment benefits

Health insurance cards cannot be used after eligibility is lost

Starting on the loss-of-eligibility date (the date of inapplicability), health insurance cards from the Yazaki Health Insurance Society cannot be used. Please submit a notification form and promptly return any cards (generally within five days).

If a health insurance card is used on or after the loss-of-eligibility date, please note that any medical care costs will later have to be returned. In this case—because the co-pay amount is 30% (10 to 20%) of the medical care costs—we will bill the insured person for the amount equivalent to the remaining 70% (80 to 90%) through their establishment. If you receive such a bill, please pay promptly. (Even if the card was used by a dependent, we will bill the insured person because they are responsible for paying their dependents' medical care expenses. Be sure to pay any such bills.)
