Japan Pension Vesting: The 10-Year Rule
Japan pension vesting asks only one question: do ten years of coverage stand behind you at 65. The answer decides whether decades of contributions pay out or sit idle.1 Since August 2017 the threshold is 10 years, not the 25 that older guides still print.2
Procedures, fees, and requirements can change. Confirm current details at the Japan Pension Service site.

Overview
Vesting, the 受給資格期間 (jukyu shikaku kikan, "qualification period"), is the minimum coverage that opens the old-age benefit. Japan sets it at 10 or more years of combined coverage across National Pension and Employees' Pension Insurance, the two halves of the social insurance pension system, with benefits starting at 65 in principle.13 Starting earlier or later is allowed, and the chosen timing adjusts the amount for life.1
The 10-year rule
Ten years means the sum of contribution-paid periods and contribution-exempted periods as Category 1, 2, or 3 insured persons.1 Part-time, full-time, salaried, and self-employed months all aggregate; the system counts coverage, not job titles. Before August 2017 the same sum had to reach 25 years, and the reform to 10 opened benefits to residents who would previously have qualified for nothing.2
Readers with coverage periods abroad should note that foreign time is outside this entry; whether it can count depends on bilateral agreements, which a planned sibling entry on totalization will cover. Employees' Pension adds one extra condition of its own: one or more months of EPI coverage alongside the basic 10-year qualification.3
The diagram shows the qualification gate and the timing choice (as of 2026).1 Forty paid years earn the full fiscal 2026 amount of 847,300 yen per year, about 70,608 yen per month (as of 2026-04-01; confirm current figures with the Japan Pension Service).14
Claiming early: from age 60
繰上げ受給 (kuriage jukyu, "early payment") opens at any age after 60 with a permanently lower amount. Claiming at 60 pays 76 percent of the age-65 amount, reflecting a reduction of 0.4 percent per month of early start, or 4.8 percent per year (as of 2026 and 2023 respectively; confirm current figures with the Japan Pension Service).15
The reduction never resets. Once early payment begins, the discounted rate applies for the rest of life, so the break-even math depends on longevity rather than on any later reversal.1 Early basic pension also closes a door: disability onset after the early entitlement date cannot open a Disability Basic Pension claim.1
Claiming late: up to age 75
繰下げ受給 (kurisage jukyu, "delayed payment") raises the amount for starts at 66 or later. Waiting until 75 or beyond pays 184 percent of the age-65 amount, reflecting an increase of 0.7 percent per month of delay, or 8.4 percent per year (as of 2026 and 2023 respectively; confirm current figures with the Japan Pension Service).15
Like the early discount, the late premium is permanent. The rate never floats with later policy; the rate locked at first receipt runs for life.1 Residents still working at 65 often pair the delay with the working-pension rules in the Employees' Pension entry.
How to claim
File the old-age benefits application at the nearest JPS branch office or pension consultation center.1 Residents in Japan receive the pre-printed form about three months before pensionable age, with their records already entered.1 Early and delayed starts each need their additional application form on top of the base claim.16
One paperwork trap catches short-history claimants. Where combined paid and exempted periods total under 25 years, the claim must attach a certified address-history extract from the family registry records.1 Pull that document before the filing appointment, not during it.
Even residents who will never reach 10 years leave a pension trail that immigration can read in permanent residency screening. Leavers with short coverage should use the lump-sum exit path within its deadline, and stayers should protect every month; the compliance entry explains the review.
Good to know
The adjustment is permanent, not a loan against later years
Neither the early discount nor the late premium revisits its rate. Model lifetime totals under several longevity assumptions before choosing, because the signature is final.1
Early basic pension blocks later disability basic pension
The trade is structural: once early old-age payment is entitled, a later disability onset cannot generate a Disability Basic Pension claim.1 Readers with health risks should price that lost option into the early-claim math.
Short-stay leavers have a separate exit path
Non-Japanese residents leaving with short coverage who will never vest can claim the lump-sum withdrawal within two years of departure, provided they are no longer covered.3 That path belongs to the planned lump-sum entry; the point here is that doing nothing forfeits both the pension and the refund.
