Japanese pay and benefit calculators

what actually reaches you, while working and while not

A Japanese salary is quoted gross, and the gap to what arrives is larger than most people expect. Benefits during leave are paid by insurance rather than the employer, are not taxed, and suspend social insurance contributions. None of that is obvious from the headline figure, so here it is with your own numbers.

The salary carries across

All three use the same annual figure, so entering it once is enough. Company pages carry it over too — every listed company's average pay links straight in (company index, rankings).

How it adds up over a career

A single year is one thing; 38 years is another. Lifetime earnings after tax applies the same deductions to every year from 22 to 60, for each listed company.

The rules behind them

What the law requires, what is only convention, and when each rule took effect: guides. National levels for pay, leave and hours: benchmarks.

Before you rely on these

They are estimates. Social insurance uses grade tables and tax depends on credits not modelled here. Check your payslip, your withholding statement, or Hello Work.
Rates change. Social insurance rates are set annually; employment insurance benefits are revised every 1 August. Each page states the date it reflects.
Amounts are in units of 10,000 yen (man), the unit Japanese salaries are quoted in. There is no retirement-payout calculator here — the tax treatment is a Japanese-resident matter and the Japanese edition covers it.
