How Much Japanese Pension Will You Actually Get?

Quick Answer: The basic pension is arithmetic, not a mystery: ¥847,300 × your months of coverage ÷ 480. Twenty years gets you exactly half. Company employees add a second earnings-linked layer on top, and a younger dependent spouse can add up to ¥423,700 a year — a supplement most people never hear about until they claim.

"How much will I actually get?" is the question the pension system answers worst. The official material gives you a formula with four exemption multipliers and two different rate periods; the unofficial material gives you a headline number that assumes a career you haven't had.

The real answer is calculable, and the shape of it is simple enough to hold in your head. This guide walks through each layer with the FY2026 figures — and flags two additions that are easy to miss and worth real money.

This is educational information, not financial or pension advice. Amounts revise every April and your entitlement depends on your own record — confirm your position with the Japan Pension Service. For the eligibility question rather than the amount, start with Japan pension for foreigners.

How is the basic pension actually calculated?

One formula, and it's worth seeing plainly:

Full amount × (months you paid ÷ 480)

480 months is 40 years, ages 20 to 60. That's the denominator behind every "full pension" figure you've read, and it's why almost no foreign resident ever sees one.

At the FY2026 full amount of ¥847,300 a year:

Coverage Annual basic pension Monthly
40 years (480 months) ¥847,300 ¥70,608
20 years (240 months) ¥423,650 ~¥35,300
10 years (120 months) ¥211,825 ~¥17,650

Ten years is the minimum that gets you anything — but as the table shows, qualifying and getting a meaningful amount are two different milestones. Every additional year of coverage adds roughly ¥21,000 a year, for life.

That's the number worth sitting with. A year of Japanese pension coverage buys about ¥21,000 of annual income from 65 until you die, index-linked. Whether that's a good deal depends on how long you live.

What if you had exempted or unpaid periods?

Exempted months still count — at a reduced weight, not zero. This matters for anyone who was a student, between jobs, or on a low income and filed for exemption rather than simply not paying.

For periods from April 2009 onward:

Exemption type Counts as
Full exemption (全額免除) 4/8 of a paid month
Three-quarters exemption 5/8
Half exemption 6/8
Quarter exemption 7/8

Periods before April 2009 use lower multipliers — a full exemption counted as one-third rather than a half.

The important distinction: formally exempted months are weighted; simply unpaid months are worth nothing. If you were ever eligible for exemption and didn't apply, that's the gap. It's also why the student exemption is worth filing for even when you have no income — you're buying half-credit for free.

Rather than work your own case out by hand, run it through the Japan Pension Estimator.

How does the employees' pension add to it?

If you've been a company employee, a second earnings-linked layer sits on top of the flat basic pension. Roughly:

Average standard remuneration × a small statutory rate × months of coverage

The rate is 7.125/1000 for months up to March 2003 and 5.481/1000 from April 2003 onward — which for most foreign residents means only the second rate applies.

One thing that formula hides: the law takes the higher of two calculations. Alongside the current one there is a legacy calculation, 従前額保障, carried over from the old system — and the Japan Pension Service is explicit that 「上記の計算式で算出した額が従前額…を下回る場合は、従前額が報酬比例部分の額になります」. Where the current formula produces the smaller number, the legacy figure is used instead.

The gap is usually small, but the consequence matters: a figure you work out from the rate above is a floor, not the final answer. Your own number is on your ねんきんネット record or available from a 年金事務所, and it will not be lower than what this formula gives you.

Two consequences follow. Higher salary means a bigger second layer, so unlike the basic pension it isn't flat. And the employees' pension is the reason the government's model household reaches ¥237,279 a month in FY2026 — that figure is a standard earner's two layers plus a spouse's basic pension, not two basic pensions.

Treat the model household as a benchmark for a full Japanese career, not a forecast for yours.

Is there extra for a spouse?

This is the addition almost nobody knows about, and for international couples it can be the largest single line on the page.

If you have 20 years or more of employees' pension coverage and a dependent spouse under 65 when you reach 65, your pension includes a 加給年金額 — a spouse supplement. In FY2026 the base is ¥243,800 a year, and for anyone born on or after 2 April 1943 a special addition takes it to ¥423,700 a year.

Look at that against the table above: the spouse supplement can be worth roughly the same as twenty years of basic pension contributions. There are also amounts for dependent children — ¥243,800 each for the first two, ¥81,300 for the third and beyond.

It stops when your spouse turns 65, divorces, dies, or becomes entitled to their own employees' pension. That last condition catches couples out: if your spouse builds their own 20-year employees' pension record, the supplement can end.

For couples where one partner is meaningfully younger — common in international households — this is a real planning input rather than a footnote. See the dependent-spouse pension in Japan.

Can you work and still receive it?

Yes, and the rules just got considerably more generous.

Under the 在職老齢年金 system, working while drawing an employees' pension can suspend part of it. The suspension kicks in when your monthly pension plus your monthly earnings equivalent exceed a threshold — and from 1 April 2026 that threshold rose from ¥510,000 to ¥650,000 a month.

Above it, the reduction is:

Basic monthly amount − (basic monthly amount + monthly earnings equivalent − ¥650,000) ÷ 2

The Japan Pension Service's own example: someone with ¥100,000 of monthly pension and ¥460,000 of monthly earnings used to lose ¥25,000 a month. Under the new threshold they lose nothing.

For anyone planning to work into their sixties — which describes a lot of people arriving in Japan mid-career with a short contribution record — this materially changes the maths of claiming at 65 versus deferring. The deferral mechanics are in Japan pension for foreigners, and how it fits your wider plan in how much of your Japan paycheck can go toward FI and how to invest in Japan.

Frequently Asked Questions

How is the Japanese basic pension calculated?

The full annual amount multiplied by your months of coverage divided by 480. Four hundred and eighty months is forty years, ages 20 to 60. At the FY2026 full amount of ¥847,300, twenty years of coverage produces ¥423,650 a year and ten years produces ¥211,825.

How much is one year of Japanese pension contributions worth?

Roughly ¥21,000 of annual basic pension, payable for life from 65 and revised each April. A company employee also builds the earnings-linked employees' pension on top, which depends on salary rather than being flat.

Do exempted years count toward my Japanese pension?

Yes, at reduced weight. From April 2009, a fully exempted month counts as 4/8 of a paid month, rising through 5/8, 6/8 and 7/8 for partial exemptions. Months that were simply unpaid, without a formal exemption, count for nothing — which is why applying for exemption matters even at zero income.

What is 加給年金 and do I qualify?

A supplement added to your employees' pension if you have 20 years or more of coverage and a dependent spouse under 65 when you turn 65. In FY2026 it is worth up to ¥423,700 a year, plus amounts for dependent children. It ends when your spouse turns 65 or becomes entitled to their own employees' pension.

Can I work and still receive my Japanese pension?

Yes. Part of the employees' pension can be suspended if your monthly pension plus monthly earnings equivalent exceed a threshold — but that threshold rose from ¥510,000 to ¥650,000 a month on 1 April 2026, so far fewer people are affected than before.
