Quick answer
A ¥6,000,000 salary nets about ¥4,262,000 a year — about ¥355,000 per month — after ~¥557,000 income tax, ~¥302,000 resident tax and ~¥880,000 shakai hoken. Change the salary and every step re-derives instantly.
What This Calculator Really Does
Japanese payslips confuse expats because three separate systems bite at once: national income tax (progressive, withheld monthly), resident tax (set by your city, paid the FOLLOWING year), and shakai hoken (social insurance shared with your employer). The calculator walks each one in order so the final gikyu (take-home) is explainable line by line.
The systems it models
- Employment income deduction: roughly ¥480,000 plus 10% of salary — subtracted before tax.
- National income tax: 5% to ¥1.95M taxable, 10% to ¥3.3M, 20% to ¥6.95M, 23% above (2025 brackets).
- Resident tax: ~10% flat (6% municipal + 4% prefectural), levied on LAST year's income from June.
- Shakai hoken: ~14.66% employee share (health 5%, pension 9.15%, unemployment 0.5%) up to the standard monthly remuneration caps.
Worked example with real numbers
Salary ¥6,000,000: employment deduction ≈ ¥1,080,000 → income after deduction ≈ ¥4,920,000. Income tax ≈ ¥557,000; resident tax ≈ ¥302,000; shakai hoken ≈ ¥880,000 → annual net ≈ ¥4,262,000 (¥355,000/month).
Reading the result
The donut splits your gross across the four systems; the extra line reports the annual net. Year-end adjustment (nenmatsu chosei) refunds small over-withholdings in December — the calculator shows the statutory amounts, not your company's exact withholding. Bonuses attract their own withholding tables and are not modelled.

Frequently Asked Questions
How is take-home pay calculated in Japan?
Gross salary minus the employment-income deduction gives taxable income; national income tax (5–23% brackets) is withheld monthly, resident tax (~10%) is paid the following year, and shakai hoken (~14.66% employee share) comes off each payslip. The steps panel itemises all four.
What is shakai hoken in Japan?
Social insurance: health insurance (~5%), employees pension (~9.15%) and unemployment insurance (~0.5%) — about 14.66% of your standard monthly remuneration, matched roughly equally by your employer.
Why is resident tax separate from income tax?
Resident tax belongs to your city and prefecture (~10% combined) and is billed a year in arrears from June. New arrivals enjoy a nearly tax-free first year — the calculator still includes it for steady-state accuracy.
