How national and local tax work
Every Japanese paycheque starts with these national brackets, applied to income after the employment income deduction and basic exemption, plus a 2.1% reconstruction surtax on the result.

| ￥1,950,000 – ￥3,300,000 | 10% |
| ￥3,300,000 – ￥6,950,000 | 20% |

On top of national tax, Okayama charges the standard 10% local inhabitant tax (split between the prefecture and municipality) plus a small flat per-capita levy — the same rate as every other prefecture, since Japan's local-tax rate has been standardised nationwide since 2007.

What this estimate simplifies
This models a single filer with no dependents. It doesn't account for furusato nozei (hometown tax donations), iDeCo contributions, kaigo hoken (which applies only from age 40), or income beyond salary. See Aftertax's European methodology for the same principle of transparent simplifications applied across the site.
Common questions
Is this my exact take-home pay in Okayama?
No. It's an estimate for comparison, based on 2026 national tax, local inhabitant tax, and mandatory social-insurance rules for a single filer with no dependents. It doesn't account for dependents' deductions, furusato nozei (hometown tax donations), or income other than salary.
What does the Okayama figure include?
National income tax on the progressive brackets after the employment income deduction and basic exemption, plus the 2.1% reconstruction surtax on that national tax; local inhabitant tax at the standard 10% rate; and mandatory shakai hoken — kosei nenkin employee pension at 9.15% (capped), koyo hoken employment insurance at 0.5%, and Kyokai Kenpo health insurance.
Does health insurance really cost the same in Okayama as everywhere else?
In reality, no — Kyokai Kenpo health-insurance rates do vary by prefecture, typically by around a percentage point. This calculator uses the Tokyo rate as a single national reference figure rather than 47 separately-sourced rates, the same way it uses Zurich as a reference point for Switzerland's cantons and a national-average municipal rate for Sweden. Your real health-insurance line in Okayama may be slightly higher or lower than shown here.
Why might my real Okayama take-home pay be different?
A Chugoku-region prefecture with a strong textile and steel manufacturing base, and well-known produce including peaches and grapes. On the tax side: common reasons your real figure would differ include dependents, iDeCo or furusato nozei contributions, kaigo hoken (long-term care insurance, which applies only from age 40), or income beyond salary. Always confirm important numbers with a tax professional.
