Japan's Pension System Explained for Foreign Residents — Premiums, Benefits, and What You Need to Know in 2025
Last updated: February 2026 ｜ Reflects FY2025 premiums, the 2025 Pension Reform Act, and the 2027 visa-renewal compliance rule
Every foreign resident in Japan aged 20 to 59 is legally required to enroll in the national pension system — no exceptions for nationality. This has been the law since 1982, when Japan removed the citizenship requirement from its National Pension Act, and it applies to everyone holding a Residence Card, from English teachers and engineers to students and freelancers.
If you've ever looked at your paycheck and wondered why a chunk disappears into kōsei nenkin every month, or why you keep receiving payment slips from the Japan Pension Service despite planning to leave eventually, this guide is for you. Japan's pension system is often dismissed as a "tax on foreigners," but that's an oversimplification that can cost you real money. There are mechanisms to get some of it back when you leave, ways to carry your contribution periods to your home country, and — starting June 2027 — serious immigration consequences for not paying.
This article explains the complete architecture of Japan's pension system from a foreign resident's perspective.
The "Two-Story Building": How Japan's Pension Tiers Work
Japan's public pension is universally described in Japanese as nikaitate — a "two-story building." The first floor provides a universal safety net; the second floor rewards employment and higher earnings.
Tier 1: National Pension (Kokumin Nenkin) covers every resident aged 20 to 59 and provides three types of benefits: Old-Age Basic Pension, Disability Basic Pension, and Survivors' Basic Pension. If you're self-employed, freelancing, studying, or between jobs, you pay a flat monthly premium regardless of your income.
Tier 2: Employee's Pension (Kōsei Nenkin) covers salaried workers at companies and civil servants. These workers are automatically enrolled in both tiers. Their employers handle all paperwork and split premiums 50-50. At retirement, they receive the Basic Pension from Tier 1 plus an earnings-related supplement from Tier 2.
The system classifies everyone into one of three categories:
Category 1 — Self-employed, freelancers, students, and the unemployed. You enroll at your municipal office and pay the flat National Pension premium yourself.
Category 2 — Company employees and civil servants. Your employer enrolls you in both National and Employee's Pension. Premiums are deducted from your salary automatically.
Category 3 — Dependent spouses of Category 2 members (earning under ¥1.3 million/year). You're enrolled in National Pension but pay zero premiums — costs are collectively covered by all Category 2 contributors.
Registering at City Hall: What Happens When You Arrive
The enrollment obligation stems from Article 7 of the National Pension Act, which covers any person "who has an address in Japan, is aged 20 or older and under 60." The statute contains no nationality clause — a deliberate omission since 1982.
When you complete resident registration (jūmin tōroku) at your municipal office, you should head to the National Pension counter within 14 days. Bring your Residence Card and proof of address. You'll receive a Basic Pension Number — a unique identifier used for all pension-related interactions. Payment slips arrive by mail from the Japan Pension Service shortly after.
If you arrived as a company employee, your employer handles Employee's Pension enrollment directly, so no city hall visit is needed for pension purposes. Since October 2024, the Japan Pension Service has started using resident registration data to proactively enroll newly arrived foreigners, aiming to close the gap between registration and enrollment.
FY2025 Premium Amounts and How to Pay
National Pension
The monthly premium for FY2025 is ¥17,510 (up ¥530 from FY2024), totaling ¥210,120 per year. An optional supplementary premium of ¥400/month is available for Category 1 members who want a modest benefit boost at retirement.
Advance payment yields meaningful savings. By bank transfer: ¥1,190 off for a 6-month prepayment, ¥4,400 off for one year, and ¥17,010 off for two years (paying ¥408,150 instead of ¥420,240). Credit card and cash prepayments offer slightly smaller discounts. Even a simple monthly early-debit arrangement saves ¥60/month — ¥720 per year.
Payment methods include bank transfer, post office, convenience stores (for amounts up to ¥300,000), credit card (Visa, Mastercard, JCB, Amex, Diners), Pay-easy electronic payment, and smartphone apps — PayPay, au PAY, d-barai, Rakuten Pay, and PayB have been accepted since February 2023.
Employee's Pension
The contribution rate is a flat 18.3% of standard monthly remuneration, split exactly 50-50 between employer and employee (9.15% each). The system uses 32 grades of standard monthly remuneration, ranging from ¥88,000 to ¥650,000. Bonuses are capped at ¥1,500,000 per payment occasion and subject to the same 18.3% rate.
Old-Age Pension: Eligibility, Amounts, and Claiming Strategies
To receive the Old-Age Basic Pension, you need a minimum 10-year qualifying period (reduced from 25 years in August 2017). This includes months of premium payment, approved exemptions, deferrals, and combined periods from social security agreement countries.
The full annual amount for 40 years of contributions in FY2025 is ¥831,700 (approximately ¥69,308/month). For fewer than 40 years, the pension is calculated proportionally: full amount × (credited months ÷ 480). Twenty years of full contributions yields approximately ¥415,850/year.
The Old-Age Employee's Pension adds an earnings-related component on top. The calculation uses your salary history: for periods before April 2003, the formula is average monthly remuneration × 7.125/1000 × months; for periods from April 2003 onward, it's average remuneration × 5.481/1000 × months. The government's model couple — a husband with 40 years of enrollment averaging ¥455,000/month and a wife receiving the full basic pension — receives a combined ¥232,784/month in FY2025.
Claiming flexibility is substantial. The standard age is 65, but you can start early from age 60 with a permanent reduction of 0.4% per month (up to 24% at age 60). Alternatively, deferring to as late as age 75 earns a permanent increase of 0.7% per month — a maximum 84% boost. You can defer the Basic and Employee's Pensions independently, allowing strategic optimization. Deferring to 70 gives a 42% increase, with the break-even point around age 82.
For those still working past 65: if your combined monthly pension and wages exceed ¥510,000, the excess portion triggers a partial pension suspension.
Disability Pension: A Safety Net You May Not Know You Have
Japan's disability pension is perhaps the most underappreciated benefit for foreign residents. If you become ill or injured while enrolled, the system provides income replacement regardless of nationality.
Disability Basic Pension covers Grade 1 and Grade 2 disabilities. FY2025 amounts are ¥1,039,625/year for Grade 1 and ¥831,700/year for Grade 2, with additional supplements for dependent children (¥239,300 for each of the first two children, ¥79,800 for each additional child).
Disability Employee's Pension adds earnings-related benefits on top. Grade 1 receives the earnings-related amount × 1.25 plus a spouse supplement. Grade 2 receives the straight earnings-related amount plus the spouse supplement. Grade 3 — which has no basic pension equivalent — provides only the earnings-related portion, with a minimum guarantee of ¥623,800/year.
Three requirements must be met: your initial medical examination must fall during an insured period; at least two-thirds of your total insured months must be paid or exempted (or no unpaid months in the most recent year — a special rule valid through March 2036); and your condition must meet the disability grade criteria at the certification date.
The second requirement is critical. If you've been ignoring premium payments without applying for any exemption, an unexpected illness or accident could leave you ineligible for disability benefits. Filing for an exemption — which costs nothing — protects this safety net.
Survivors' Pension: Protection for Your Family
Survivors' Basic Pension is paid to a surviving spouse with dependent children or directly to the children. The FY2025 base is ¥831,700/year plus child supplements, totaling ¥1,071,000/year for a spouse with one child.
Survivors' Employee's Pension covers a wider range of beneficiaries in priority order — spouse and children first, then parents, grandchildren, and grandparents. The amount is three-quarters of the deceased's earnings-related pension, with a 300-month floor for short enrollment periods. A transitional supplement of ¥623,800/year is available for eligible widows aged 40–65 without dependent children.
A major reform arriving in April 2028 will equalize gender treatment and introduce 5-year time-limited benefits for childless spouses under 60.
Exemptions and Deferrals: What to Do If You Can't Pay
Japan offers robust programs for those who can't afford premiums, and understanding them is essential — because approved exemptions count as compliant for visa renewal, while unapproved non-payment does not.
The Student Payment Special System allows students at approved institutions — including language schools with courses of one year or more — to defer premiums entirely. Only the student's own income is assessed, with a threshold of ¥1,280,000.
Income-based exemptions assess the applicant's, spouse's, and household head's income across four tiers: full exemption at ¥670,000, three-quarter at ¥880,000, half at ¥1,280,000, and quarter exemption at ¥1,680,000 (single person, no dependents). For partial exemptions, the remaining portion must be paid — otherwise, the period becomes fully unpaid.
The payment deferral system is available for Category 1 persons under age 50 and assesses only the individual's and spouse's income — not the household head's. This is particularly useful for young foreign residents living with a host family or in shared housing with high-income housemates.
Exempted periods count toward benefit calculations at reduced rates (full exemption = 1/2 credit; three-quarter = 5/8; half = 3/4; quarter = 7/8). Student deferrals and payment deferrals count toward the qualifying period but add zero to the benefit amount. All exempted and deferred periods can be retroactively paid within 10 years, converting them to full-credit periods.
Three Strategic Options for Foreign Residents
When leaving Japan is a possibility — whether near or far — you face a fundamental choice. Each option has trade-offs that depend on your long-term plans.
Option 1: Qualify for the Japanese Pension
Accumulate 10 or more qualifying years and you earn a permanent right to the Old-Age Basic Pension (and Employee's Pension if applicable), payable anywhere in the world from age 65. Periods from social security agreement countries count toward the 10-year threshold, so residents from agreement countries may find this more achievable than expected.
Option 2: Claim the Lump-Sum Withdrawal Payment
Foreign nationals who leave Japan with 6+ months of contributions and haven't met the 10-year qualifying period can claim a one-time refund within 2 years of departure. The current cap is 60 months (5 years) of contributions. For National Pension, the maximum is approximately ¥525,300 at FY2025 rates. Employee's Pension amounts vary by salary. A 20.42% tax is withheld on Employee's Pension refunds but is partially recoverable through a tax representative.
Critical warning: claiming the lump-sum permanently erases the contribution period. It can never be used for qualifying or totalization.

Option 3: Use Social Security Agreements for Period Totalization
Japan has agreements with 23 countries — 19 with full totalization (US, Germany, France, Canada, Australia, Brazil, India, Philippines, and others) and 4 with double-coverage prevention only (UK, South Korea, China, Italy). Austria became the 24th country in December 2025. Totalization lets you combine contribution periods across countries to meet eligibility thresholds, with each country paying proportionally.

June 2027: Visa Renewal Will Require Pension Compliance
In November 2025, Health Minister Kenichiro Ueno formally announced that starting June 2027, unpaid National Pension and National Health Insurance premiums will be grounds for denying visa renewals and status changes. A data-sharing system linking municipal payment records to the Immigration Services Agency via My Number is being built during FY2026.
All visa types requiring renewal are affected — work visas, student visas, dependent visas, and Specified Skilled Worker visas. Permanent residents face a separate risk: a 2024 Immigration Act revision already allows revocation of permanent residence for failure to meet public obligations.
The key distinction is between approved exemption and unapproved non-payment. Anyone with a properly filed exemption, deferral, or student deferral is fully compliant. Simply not paying without applying for any program constitutes delinquency. The government has signaled that the policy targets those who are delinquent and refuse to respond to collection efforts, though the precise threshold for denial has not yet been formally defined.
Action point: If you are currently not paying and haven't applied for an exemption, visit your municipal office immediately. Filing costs nothing, protects your visa, and preserves your eligibility for disability and survivors' pensions.
The 2025 Pension Reform: What Changed for Foreigners
The pension reform law enacted on June 13, 2025 contains several provisions with major implications for foreign residents.
Lump-sum withdrawal cap rises from 5 to 8 years. The maximum period covered increases from 60 to 96 months, aligning with the new Ikusei Shūrō training pathway (3 years) plus Specified Skilled Worker Type 1 (5 years). Implementation is expected by approximately 2029. A new rule simultaneously blocks lump-sum claims by anyone holding a valid re-entry permit.
Employee's Pension coverage expands. An estimated 2 million additional workers — including many foreign part-timers — will be brought into the system. The ¥88,000/month wage threshold is abolished in October 2026, and the company size requirement is progressively eliminated, reaching full removal by October 2035. Previously uncovered individual business categories (restaurants, beauty salons) with 5+ employees join from October 2029.
Standard remuneration cap increases in three stages: ¥680,000 in September 2027, ¥710,000 in September 2028, and ¥750,000 in September 2029. Higher-earning professionals will see increased deductions but correspondingly higher future benefits.
Other notable changes include extending iDeCo enrollment to age 70 (January 2027), raising the in-work pension suspension threshold to ¥620,000 (April 2026), and the survivors' pension gender equalization reform (April 2028).
Three Things Every Foreign Resident Should Do Now
1. Check your enrollment record. Register for "Nenkin Net" (nenkin.go.jp) to view your complete contribution history and projected pension amounts online.
2. Apply for an exemption if you can't pay. Even if you can't afford premiums, filing for an exemption or deferral costs nothing and protects your visa, your qualifying period, and your disability/survivors' safety net.
3. Compare all three options before deciding. The lump-sum withdrawal is quick cash, but it permanently erases your contribution period. If your home country has a social security agreement with Japan, totalization may be worth significantly more over your lifetime. Always compare before you claim.
Japan's pension system is not designed to be a trap for foreign residents — it's a social insurance program that provides real value when properly understood. With the 2027 visa compliance check approaching, the cost of ignorance has never been higher.
