If you live in Japan and are between 20 and 59 years old, you are generally required to enroll in the National Pension system (Kokumin Nenkin).
This guide explains who needs to enroll, how to apply, how much it costs, and what happens if you do not pay.
What Is the National Pension System?
Japan’s National Pension is a mandatory public pension program.
It provides:
- Basic retirement pension
- Disability pension
- Survivor benefits
Enrollment is required for most residents, including foreigners staying longer than three months.
Who Needs to Enroll?
You must enroll if you:
- Are 20–59 years old
- Have completed your Address Registration
- Are not enrolled in Employee Pension through your employer
If you work full-time, your company usually handles pension enrollment automatically.
You will need your My Number for registration procedures.
Required Documents
Bring the following to your local city or ward office:
- Residence card
- My Number card or notification
- Pension booklet (if previously issued)
- Bank account details (for automatic payments)
If you do not yet have one, see our guide to opening a Bank Account in Japan.
How to Apply Step-by-Step
- Visit your local municipal office.
- Request enrollment in National Pension.
- Submit required documents.
- Choose a payment method (bank transfer recommended).
- Receive your pension number and booklet.
Processing time is usually within the same day.
How Much Does It Cost?
The standard monthly premium is set nationally and adjusted annually.
As of recent years, it is approximately ¥16,000–¥17,000 per month.
However, you may qualify for:
- Full exemption
- Partial exemption
- Student payment deferment
If your income is low, apply for reduction at the same office.
What Happens If You Do Not Pay?
Unpaid premiums may result in:
- Loss of eligibility for disability pension
- Reduced future pension amount
- Back payment demands
In some cases, unpaid contributions may affect long-term residency or permanent residency applications.
Lump-Sum Withdrawal for Foreigners
If you leave Japan permanently, you may apply for a Lump-Sum Withdrawal Payment.
Conditions generally include:
- Paid pension contributions for at least six months
- Application within two years of leaving Japan
This allows partial recovery of paid contributions.
Difference Between National Pension and Employee Pension
| National Pension | Employee Pension |
|---|---|
| Fixed premium | Income-based premium |
| Individual payment | Shared with employer |
| Basic pension only | Includes earnings-related portion |
If you are employed full-time, your employer handles the process.
When to Notify the City Office
You must notify your local office if:
- You change your address
- You switch jobs
- You leave Japan
- Your employment status changes
If you move, remember to update your Address Registration.
Important Notes
- Pension rules may change yearly.
- Premium amounts are nationally standardized but exemptions depend on income.
- Always keep your pension number safe.
