The Lump-Sum Withdrawal Payment: Getting Some of Your Japanese Pension Back

Many foreign workers who leave Japan spent years paying into a pension they will never draw a single yen from. Between shakai hoken (社会保険, employees' insurance) and kokumin nenkin (国民年金, National Pension), Japan's old-age pension generally requires at least 10 years of contributions before it pays out anything, and most foreign residents leave the country well before crossing that line. Rather than let those contributions simply vanish, Japan offers a partial, one-time refund: the Lump-sum Withdrawal Payment (dattai ichijikin 脱退一時金). What follows covers who generally qualifies, how the payment is worked out, the tax that gets carved off the top before it reaches you, and a 2025 reform that is quietly rewriting parts of the rules.

This is general information, not individual advice. Whether you personally qualify, how much you would receive, and how much tax you can recover depend on your contribution history, visa status, and personal circumstances. For a decision about your own case, contact the Japan Pension Service (日本年金機構), your local pension office, or a licensed professional (社会保険労務士 for pension matters, 税理士 for tax).

What the lump-sum withdrawal payment is

The Japanese pension system is built around long-term participation: Employees' Pension Insurance (厚生年金保険, for company employees) and the National Pension (国民年金, the base layer everyone in Japan pays into) both assume you will keep contributing for years and eventually collect an old-age pension. Foreign workers on a few years in Japan often contribute for a while and then leave without ever reaching that threshold, having paid in with nothing to show for it. The lump-sum withdrawal payment exists specifically to return part of those contributions in that situation, rather than simply forfeiting them. It is a one-time payment, not a pension, and the Japan Pension Service (JPS, 日本年金機構) — the public body that administers the country's pension programs — is who reviews and pays it.

Who generally qualifies

Based on the Japan Pension Service's published conditions, you are generally in scope for the lump-sum withdrawal payment if all of the following are true:

On top of the eligibility itself, there is a filing deadline: you need to submit your claim within two years of the date you left Japan and stopped being covered by these pension systems. Miss that window and, as a rule, the right to claim lapses. None of this is a substitute for checking your own situation. Dual-coverage history, totalization agreements between Japan and some other countries, and edge cases around re-enrollment can all change the answer, so use the list above to get oriented and confirm the details for your own case.

How much counts, and the 2021 change to the cap

The payment is calculated from your number of months of contributions (up to a cap) and the average of your standard remuneration during that period, using a formula and rate table that the Japan Pension Service publishes and periodically updates. This guide will not quote a specific yen amount, because the actual figure depends entirely on your own contribution history and the rate table in effect at the time — for your own estimate, use JPS's official materials or ask them directly.

What is worth knowing is the cap itself, because it has moved before and is set to move again. Since April 2021, up to 60 months (5 years) of contributions can count toward the calculation; before that change, the limit was 36 months (3 years). In other words, if you worked in Japan for, say, seven years, only the first five years' worth is used in the calculation under the current rule — the rest does not add to the payment. As covered below, this cap is scheduled to rise again under the 2025 pension reform, though not immediately.

How to apply

The claim form (脱退一時金請求書, "Lump-sum Withdrawal Payment Claim Form") is published by the Japan Pension Service in 14 languages, including English, each paired with the Japanese original, along with an example-entry guide and a spreadsheet version. You can get it from JPS's English-language site, a Japan Pension Service branch office, or a municipal National Pension counter. A few practical points:

The 20.42% withholding tax — and the refund route

This is the part that surprises the most people: when the lump-sum withdrawal payment is actually paid out, Japan withholds 20.42% of it at source. That figure is the standard national withholding rate applied to Japan-source retirement-type income paid to a non-resident (20% income tax plus a 2.1% surcharge for post-disaster reconstruction funding), and it applies automatically because by the time the payment is made, you are typically already a tax non-resident of Japan.

That withholding is not necessarily final, though. Japan's tax system has a separate procedure — elective taxation on retirement income (退職所得の選択課税) — that lets a non-resident ask to have that income taxed the way a resident's would be, which is often less than the flat 20.42%. If the recalculated amount is lower than what was withheld, the difference is refunded. In practice this generally means appointing a tax representative (納税管理人, nozei kanrinin) — someone with an address in Japan who can file the return and receive the refund on your behalf — then filing with the National Tax Agency (国税庁) once the payment amount is finalized. The agency's own published examples work through this exact scenario for pension lump-sum withdrawal payments.

This is general information about how the mechanism works, not a projection of what you would personally get back or an endorsement of any particular tax representative service — those numbers depend on your income, contribution period, and filing details. For your own figures, the National Tax Agency or a licensed tax accountant (税理士) is the right contact, not this guide.

The 2025 pension reform: what changes, and what doesn't yet

Pension law is not static, and this section covers a reform that was enacted but, as of this guide's confirmation date, has not yet taken effect. Check the Japan Pension Service's current materials before relying on any date here.

In June 2025, Japan's Diet passed a pension reform law (令和7年法律第74号) that changes the lump-sum withdrawal payment in two ways relevant to this guide:

Here is the part that matters most for planning: according to the government's own published overview of the law, both of these changes take effect on a date to be fixed later by cabinet order, no later than four years after the law's promulgation (the law was promulgated in June 2025, so the outer deadline is around mid-2029). That date had not been set as of this guide's confirmation date. Some secondary sources online describe the change as effective from a specific date already — treat any such claim with caution and confirm current status directly with the Japan Pension Service before you plan around it, since a specific implementation date has not yet been fixed.

A few things this payment is not

Where this fits if you're leaving Japan for good

The lump-sum withdrawal payment is usually just one item on a longer departure checklist. If you are working through the rest of it, you may also find it useful to look at what happens to your health insurance after you quit your job, how residence tax (juuminzei) gets settled when you leave partway through the tax year, and whether your My Number card needs to be returned or dealt with before departure. Handled separately, each of these is a manageable form; handled as a batch a few weeks before you fly out, they tend to be less stressful than discovering them one at a time.
