A 5-Million-Yen Salary in One Chart — Where ¥1.1M Goes, and How It Compares to 10 Years Ago
Take-home pay on a ¥5 million (approx. $33,000) annual salary is roughly ¥3.9 million. Where does the missing ¥1.1 million go? This article visualizes the breakdown — employee pension, health insurance, income tax, and resident tax — and traces how 'invisible deductions' have grown over the past 10 to 20 years, including the impact of the 2025 tax reform.
What Is Happening
Five million yen per year — a figure slightly above the median for Japanese salaried workers. The average salary in 2023 was 4.6 million yen, placing 5 million yen in the zone of "above average but far from comfortable."
Breaking down a 5-million-yen payslip reveals take-home pay of roughly 3.9 million yen. The approximately 1.1-million-yen difference is itemized in the deductions column of the pay statement.
Here is the breakdown:
| Deduction | Annual (est.) | Monthly (est.) | % of Gross |
|---|---|---|---|
| Employees' Pension | ¥450,180 | ¥37,515 | 9.15% |
| Health Insurance (Tokyo) | ¥243,792 | ¥20,316 | 4.955% |
| Employment Insurance | ¥27,500 | ¥2,292 | 0.55% |
| Income Tax | ~¥135,000 | ~¥11,250 | ~2.7% |
| Resident Tax | ~¥245,000 | ~¥20,417 | ~4.9% |
| Total Deductions | ~¥1,101,472 | ~¥91,790 | ~22% |
Roughly 22% of gross income is withheld, yielding a take-home ratio of about 78%. On a monthly basis without bonuses, gross pay of approximately ¥417,000 translates to ¥320,000–330,000 in the bank.
Between the ring of "5 million yen" and the amount actually deposited each month lies this 1.1-million-yen chasm.
Background and Context
Social Insurance Premiums — The Largest Deduction
Social insurance premiums represent the single largest deduction category. Combining the Employees' Pension, health insurance, and employment insurance yields approximately 720,000 yen per year — about 65% of total deductions.
The Employees' Pension premium rate was fixed at 18.3% (employer-employee combined) in 2017, with the employee's share at 9.15%. For a 5-million-yen annual income, the Standard Monthly Remuneration calculation produces a monthly deduction of ¥37,515.
Health insurance rates vary by prefecture. Under Kyokai Kenpo's FY2025 rates, the highest prefecture (Saga) charges 10.78% (combined), while the lowest (Okinawa) charges 9.44%. Tokyo stands at 9.91%. The same 5-million-yen salary can yield a difference of tens of thousands of yen in annual health insurance costs depending on work location.
Taxes — Income Tax and Resident Tax
The 2025 tax reform raised the basic deduction from ¥480,000 to ¥630,000, yielding an annual tax reduction of approximately ¥15,000 for someone earning 5 million yen. However, this reduction is nearly offset by the rise in social insurance premiums.
Resident tax is levied at a flat 10% (4% prefectural + 6% municipal) on the previous year's income, amounting to roughly ¥245,000 at this income level. Combined with income tax, the total tax burden reaches approximately ¥380,000 per year.
Comparison with 10 and 20 Years Ago — The Take-Home Gap Over Time
Take-home pay on a 5-million-yen salary varies significantly across eras.
Compared with ten years ago (2015), when the Employees' Pension rate was still being phased up toward its 2017 ceiling and health insurance rates were slightly lower, social insurance premiums alone have increased by roughly ¥36,000 per year.
Looking further back, the gap with the early 2000s is even starker. According to estimates by Financial Field, take-home pay on the same 5-million-yen salary has decreased by more than ¥300,000 compared with the early 2000s.
Three structural changes account for this gap:
- Employees' Pension rate increases: The 2004 pension reform mandated annual increases of 0.354 percentage points over 14 years, reaching 18.3% in 2017
- Health insurance rate hikes: Rates rose in stages through the 2000s, reflecting ballooning medical costs
- Introduction and increases in long-term care insurance: For those aged 40 and above, premiums have risen continuously since the system's creation in 2000

What the 5-million-yen payslip reveals is that the lived experience of "my take-home pay isn't growing" is a rational conclusion grounded in structural reality.
Even when nominal wages rise, increases in social insurance rates absorb the gains. The approximately ¥15,000 annual tax cut from the 2025 basic deduction reform does not even cover half of the ¥36,000 rise in social insurance premiums over the past decade.
This structure lies beyond individual control. Even with a raise, the increase in take-home pay consistently falls short of the increase in gross pay. The progressive structure of taxes and social insurance generates the persistent sense that "earning more doesn't mean keeping more."
Changing How We Read the Payslip
A pay statement is not merely a list of figures — it is the blueprint of the social security system translated to the individual level.
Understanding where the 1.1 million yen goes is not about expressing frustration with the system. It is the starting point for grasping the structural factors that determine one's take-home pay and for leveraging legal deduction strategies such as iDeCo (individual defined contribution pension) and the hometown tax donation program (furusato nouzei).
For instance, iDeCo contributions are fully tax-deductible. A salaried worker earning 5 million yen who contributes ¥23,000 per month can achieve combined income and resident tax savings of approximately ¥55,000 per year. Without understanding the structure of the payslip, the motivation to use such instruments is unlikely to arise.
Take-home pay on a 5-million-yen salary is approximately 3.9 million yen. Whether this figure is "high" or "low" is debatable, but the structure is clear: ¥450,000 to pension, ¥240,000 to health insurance, ¥135,000 to income tax, ¥245,000 to resident tax — the destination of every yen of the 1.1-million-yen gap is printed on the payslip.
