No. 3 insured person

Last update date March 16, 2023

What is the third insured person?

The third insured person is a person who satisfies all of the following conditions. If any of them no longer apply, you will no longer be the third insured person at that time.

  1. Must be between 20 and 60 years old
  2. No. 2 spouse dependent on the insured
  3. Not being a second insured person

For example, the third insured person falls under the following cases:

  • When married and became dependent on her husband (wife);
  • When one of the dual-income couple retires and becomes dependent on the other
  • When a husband's (wife) after receiving employment insurance (unemployment insurance)
  • When the husband (wife) of the first insured person who supports his wife (husband) gets a job and becomes the second insured person

No. 3 insured qualification cannot be obtained simply by being dependent on a company employee or public servant who has joined Employee Pension Plan (Kosei Nenkin). It is necessary to report when we acquire qualification of the third insured person or when classification changes to third insured person.

Various notifications (qualification and loss of qualification, change of Address, name change, type change, etc.) pertaining to the third insured person were made at the ward office National Pension Plan Section until March 31, 2002, but from April 1, 2002 From April 1, the company (business owner) and mutual aid union where husband (wife) works (usually in conjunction with employee health insurance).
If your husband (wife) is not currently working for a company, you must complete the procedure at the pension office in charge of your ward.

The premium for the third insured person is paid as a contribution from the pension plan that the spouse has joined to the national pension system, so there is no need to pay it individually. It is not deducted separately from the husband's (wife) salary.
In addition, even if the spouse of the second insured, if the spouse is not dependent (in principle, the annual income is 1.3 million yen or more), it will be the first insured person.

Those who have already submitted the third notification will no longer be the third insured person in the following cases. If you are under 60, please do not forget to notify the ward office National Pension Plan Section. Please bring your My Number Card or a document that can clarify your My Number Card or Basic Pension Number (In some cases, there are other required documents, so please contact us in advance).
In addition, electronic application using the minor portal is also possible. For more information, please visit the Japan pension Organization website (external site).

  1. When income increases and falls out of support
    (If you subscribe to Employee Pension Plan (Kosei Nenkin) yourself, you do not need to notify the ward office.)
  2. When divorced
  3. When a husband (wife) who is a member of Employee Pension Plan (Kosei Nenkin) retires (unemployed)
  4. When a husband (wife) who is a member of the Employee Pension Plan (Kosei Nenkin) dies
  5. When a husband (wife) who is a member of Employee Pension Plan (Kosei Nenkin) reaches the age of 65 and is eligible for pension due to old age.

For example, even if you are a third insured person when you start working part-time, if you take out social insurance (Employee Pension Plan (Kosei Nenkin)), the qualification of the third insured person will be interrupted.
In addition, if you retire from a part-time worker (not applicable to Employee Pension Plan (Kosei Nenkin)) and become a third insured person again, you will need to notify your husband's (wife) office.
