Fourteen salaries run through the 2026 Japanese model: national income tax at 5% to 45% after the employment income deduction (approximated at 25% of salary, capped) and the basic deduction, the flat 10% inhabitant tax, the 2.1% reconstruction surtax, and employee social insurance — pension, health and employment insurance. The model's simplifications are stated on the calculator page and matter at ordinary salaries, so read the ladder as a careful estimate.

Salary levels are the JPY equivalents of the US dollar amounts in the first column, converted at the reference rate snapshot of 28 October 2026 (1 USD = 157.96 JPY) and rounded to the nearest 500. The US$50,000 row is highlighted. On ¥7,898,000 a year, take-home pay in Japan is ¥5,530,678 — about ¥460,890 a month — after ¥1,214,888 in income tax and ¥1,152,434 in social contributions. Figures model a single employee with standard allowances only.
Japan's ladder is steep at the top because two taxes stack: the inhabitant tax adds a flat 10% on top of the national bands, so the marginal rate reaches 43% at the ¥11,847,000 rung and 55% at the very top (45% national plus 10% inhabitant). Social insurance rises fast at first — pension alone is 9.15% — then slows as the pension ceiling (¥7,800,000 of standard remuneration) and the health insurance cap bite, which is why the social column grows by only about ¥47,000 between the top two rungs. At middle salaries the modelled tax runs high: the real employment deduction is stepped and usually larger than the flat 25% used here, and premiums are deductible in real life.
