¥4 Million Salary in Japan: Take-Home Pay (2026)

Last updated: 6 October 2026 · figures for the 2026 tax year (令和8年分)

A ¥4,000,000 salary in Tokyo keeps ¥3,168,940 of a settled year — about ¥264,078 a month — once pension, health insurance, employment insurance, income tax and resident tax have come out; 20.8% of the salary goes. In your first months in Japan the payslip shows more, ¥276,130, because resident tax has not started.

What these figures assume

Every figure is from the calculator on this site: one employer insured through 協会けんぽ, single, no dependents, under 40, Tokyo, an ordinary business, no commuting allowance and nothing you claim for yourself. ¥4,000,000 does not divide by twelve into whole yen, so the salary is ¥333,333 a month and the year adds up to ¥3,999,996. “A settled year” means the third year onwards, once resident tax is charged on a full previous year of Japanese income.

What comes out of ¥333,333 a month

The grade (標準報酬月額) is ¥340,000, so health insurance is 10.08% and the pension 18.3% of it, half each. Social insurance comes to ¥598,956 a year against ¥232,100 of the two taxes. The employment income deduction leaves ¥2,756,800 of income; the basic exemption of ¥1,040,000 and the insurance leave ¥1,117,000 to tax, all of it in the 5% band. Each payslip withholds ¥7,290 of income tax, and December’s year-end adjustment hands back ¥30,480 — December settles the year. Resident tax runs from June: ¥15,600 in June and ¥14,500 in each month after it.

Your first three years, with and without a bonus

The same ¥4,000,000 as twelve salaries, and as a smaller salary with two bonuses, for somebody arriving in April 2026:

The first twelve months keep ¥183,330 more than a settled year. That is the resident tax not yet charged, not a pay cut when it arrives: the second year pays a small bill on nine months of 2026, and the full bill starts the June after. Why your first payslips have no resident tax has the timing.

Here the bonus version keeps ¥5,468 less. It is the insurance grades again: ¥250,000 a month sits in a lower grade, while the bonuses are insured on their exact amount. At ¥3,000,000 the rounding goes the other way. What comes out of a single bonus is in how much of a Japanese bonus you take home.

Month by month, arriving in April 2026

• April to November 2026: ¥276,130 on each payslip. These figures, like the calculator’s, take insurance from the first month; if your employer takes it a month behind, your first payslip is larger and the months after it shift accordingly.
• December 2026: ¥314,840, with ¥38,710 handed back by the year-end adjustment.
• June 2027: resident tax starts on the nine months of 2026, ¥10,500 that month and ¥9,600 after it, so the payslip settles at ¥266,530.
• June 2028: the first bill on a full year, ¥15,600 and then ¥14,500 a month.

Those dates are an illustration rather than a forecast: every year uses the 2026 rules, and insurance rates are reset each spring. The shape is the part to keep — a slow drift down on a salary that never changed.

What moves the figure

Turning 40 adds long-term care insurance of ¥33,048 a year and takes ¥28,048 off a settled year. The same salary in Osaka keeps ¥4,912 less, and in Niigata ¥11,056 more, because health insurance rates are set by prefecture.

A commuting allowance paid on top is free of income tax but counts towards the insurance grade. At ¥20,000 a month it lifts the grade from ¥340,000 to ¥360,000, adding ¥35,256 of insurance a year, so the ¥240,000 of allowance adds ¥210,044 to take-home rather than all of it.

A spouse with no income of their own is worth ¥54,900 a year here. The exemption for spouse lowers both taxes — income tax for the year from ¥57,000 to ¥37,600 and resident tax from ¥175,100 to ¥139,600 — and the monthly withholding falls from ¥7,290 to ¥5,670. What a dependent spouse is worth works through the thresholds.

Where ¥4,000,000 sits

At this salary income tax is the smallest line on the payslip: all of the taxable income is in the 5% band, and resident tax, at about 10% of a similar amount, costs about three times as much. Social insurance is the largest part by far. The share of the salary that goes rises gently with the package: 20.0% on ¥3,000,000, 20.8% here and 21.2% on ¥5,000,000. The ¥3,000,000 and ¥5,000,000 pages work the same assumptions either side of this one, and the October payslip can move too — spring overtime resets the insurance grade.

Questions people ask

How much is ¥4,000,000 a year after tax in Japan?

In Tokyo, ¥3,168,940 over a settled year, about ¥264,078 a month, for a single employee under 40 paid twelve equal salaries.

How much is the monthly payslip before resident tax starts?

¥276,130 on an ordinary month, with health insurance, pension, employment insurance and income tax taken off. Resident tax starts in the June after your first 1 January in Japan.

Is a bonus better at ¥4,000,000?

Slightly worse here: the same total paid as a smaller salary with two bonuses keeps ¥5,468 less of a settled year, because the insurance grades round differently. At other salaries it goes the other way.

These are estimates on 2026 rules and 協会けんぽ rates for Tokyo. Insurance rates are reset each spring and the timeline uses 2026 rules throughout; the basic exemption’s extra amounts are set for 2026 and 2027 and are smaller from 2028.
