Eligibility rules

The Difference Between 6, 60 and 120 Months

Three numbers that answer three different pension questions: eligibility, payment calculation, and the qualifying period.

Answer first

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.

Older calculation rule

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.

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

Which number should I check?

6
You think you have fewer than six months
Confirm the scheme and official period calculation. Do not combine rough totals across schemes.
60
You have more than 60 months
Confirm which calculation cap applies and consider the effect of a claim on all earlier Japanese coverage.
120
You are near 120 months
Request the official qualifying-period record before deciding that you qualify or do not qualify for a lump-sum payment.
A
A social security agreement may apply
Check the relevant agreement and totalization rules before giving up periods through a lump-sum payment.
?
Your coverage record is unclear
Use official records or request individual review instead of relying on an estimate.

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.
