Six, 60 and 120 months answer different questions. Six months relates to a scheme-specific minimum calculation; 60 months is the payment-calculation cap when the relevant National Pension last contribution month or Employees’ Pension Insurance final covered month is April 2021 or later; and 120 months concerns the officially confirmed qualifying period for old-age pension rights. Do not add approximate months across schemes or treat self-reported time as an official record.
6, 60 and 120 months at a glance
On a small screen, scroll the table horizontally to view all columns.
| Number | What it relates to | What it does not mean | Action |
|---|---|---|---|
| 6 months | Eligibility: a scheme-specific minimum-period calculation | Six approximate months do not confirm that every payment condition is met | Check the official National Pension or Employees’ Pension Insurance record |
| 60 months | Calculation: the cap when the National Pension last contribution month or Employees’ Pension Insurance final covered month is April 2021 or later | It is not the maximum eligible enrollment period | Confirm the relevant last contribution or final covered month and consider the effect on all earlier Japanese coverage |
| 120 months | Qualifying period: the 10-year period for old-age pension rights | It is not always the same as self-reported Japanese contribution months | Verify the official qualifying period, including possible complementary or totalized periods |
For National Pension, the applicable cap depends on the last month for which contributions were paid. For Employees’ Pension Insurance, it depends on the final covered month. If the relevant month is March 2021 or earlier, the older 36-month cap may apply. If it is April 2021 or later, the 60-month cap applies.
Which month question needs review?
The Checker’s Question 3 uses an approximate range only. It does not turn a self-reported month count into an official record or final decision.
Start the preliminary eligibility check →What six months means
Six months relates to a minimum-period condition, but the calculation is not identical for the two schemes. For National Pension, Japan Pension Service guidance uses a weighted total of contribution-paid months and certain partially exempt contribution periods. Unpaid months do not satisfy that calculation. For Employees’ Pension Insurance, the relevant insured periods under Employees’ Pension Insurance and specified related schemes must total at least six months.
Do not simply add approximate National Pension and Employees’ Pension Insurance months and treat the result as a confirmed answer. Other conditions—such as nationality, current insured status, address status, the filing period, prior benefit rights, and the officially confirmed qualifying period—also matter. The broad eligibility guide explains those separate checks.
Question 3 in the preliminary Eligibility Checker asks for an approximate coverage range. An estimate or an “unsure” answer should lead to record review, not an automatic hard-negative decision.
What sixty months means
Sixty months is a payment calculation cap, not an eligibility ceiling. For National Pension, the applicable cap depends on the last month for which contributions were paid. For Employees’ Pension Insurance, it depends on the final covered month. If the relevant month is April 2021 or later, the 60-month cap applies. A person with 61 or more months may still need the other payment conditions checked; exceeding 60 months does not by itself make a claim unavailable.
If the relevant month is March 2021 or earlier, the older 36-month cap may apply. This date distinction is about which calculation cap applies. It is not a new six-month eligibility test and it does not establish the 120-month qualifying period.
What 120 months means
One hundred twenty months refers to the officially confirmed qualifying period for Japanese old-age pension rights. It is not always identical to the number of months a person remembers paying in Japan. The qualifying period can include different Japanese pension periods and, depending on the facts, complementary periods that count for qualification without increasing the pension amount.
Coverage in a country with an applicable social security agreement may also be totalized under the agreement’s conditions. Dual coverage is not necessarily counted twice, and agreement-specific rules matter. A self-report of “around 120 months” therefore needs record verification.
If the Japan Pension Service confirms that the qualifying period is at least 120 months at the time of the claim, the lump-sum withdrawal payment cannot be claimed. This must be determined from official records and any applicable totalization rules, not from an approximate month count alone.
Why claiming after more than 60 months needs care
The calculation cap and the future treatment of coverage are different. Under the current rule, a payment for a person with 61 or more months may be calculated using up to 60 months. If you receive the lump-sum withdrawal payment, all Japanese pension coverage periods before the claim will no longer count toward future Japanese pension eligibility, benefit calculations, or totalization—not only the first 60 months.
For example, this does not mean that month 61 onward simply remains available for a future pension. If a future Japanese pension or social security agreement may matter, review the records and official information before choosing between a one-time payment and preserving coverage. See the Employees’ Pension Insurance overview for scheme context.
Common misunderstandings
- Treating more than 60 months as an automatic rejection. Sixty months is a payment-calculation cap, not an automatic eligibility cutoff.
- Equating ten years only with 120 Japanese contribution months. The official qualifying period may include other qualifying or totalized periods.
- Assuming coverage after month 60 remains for a future pension. If you receive the payment, all Japanese pension coverage periods before the claim will no longer count toward future Japanese pension eligibility, benefit calculations, or totalization.
- Treating six months as the only condition. The six-month condition is only one part of the official payment requirements.
- Treating 60 and 120 months as the same limit. One concerns payment calculation; the other concerns old-age-pension qualification.
Which number should I check?
For time-limit questions, separately review when the two-year filing period starts. The 6, 60 and 120-month concepts do not replace that deadline check.
