Japan Employer Cost of Hiring Calculator

Beyond the gross salary, Japanese employers pay their matching share of health, nursing care, and pension insurance, a larger share of employment insurance than the employee, plus rousai hoken and the child/childcare levy, both entirely employer-funded. For a ¥6,000,000 hire aged 35, that's a total load of roughly 1.16× base salary, about ￥935,100 above the quoted salary, before any recruitment fee or equipment budget.

For health insurance (4.925%, capped at ￥1,390,000/month) and pension insurance (9.15%, capped at a separate, lower ￥650,000/month), yes, it's a straight 1:1 match. Employment insurance breaks that pattern: the FY2026 employer rate is 0.85%, higher than the employee's 0.5%, not a match at all.

Rousai hoken (workers' accident compensation insurance) covers workplace injuries and occupational illness, and unlike every insurance line above, the employee pays absolutely nothing toward it, it's 100% employer-funded. The rate ranges from 0.25% for low-risk office work up to 8.8% for the highest-risk industries like mining, reflecting genuinely different accident probabilities. This calculator defaults to a representative office/tech estimate, but your real rate depends on your specific industry classification.

No, and this is a genuinely easy mix-up. The child/childcare levy (子ども・子育て拠出金) modelled here is an established, employer-only, flat 0.36% contribution (unchanged for FY2026, last revised in 2020) that funds child allowance programs, calculated on the same base as pension insurance. Separately, a NEW "childcare support levy" (子ども・子育て支援金) began collection in April 2026 as a surcharge on health insurance premiums, split between employer and employee, applying to all enrollees including singles and childless households. The two are legally distinct programs with different funding mechanisms; this calculator models only the established employer-only levy, not the new split-cost one, since its rates are still stabilizing.

Japan's "standard monthly remuneration" system uses separate ceilings for different insurance types. Health insurance is capped at ￥1,390,000/month, while pension insurance uses a much lower ￥650,000/month ceiling. For a high earner, pension contributions stop growing well before health insurance contributions do, which is why the employer's proportional load shrinks faster for senior hires than a single flat-rate model would suggest.

Japan's roughly 15-16% combined statutory rate sits below Germany's roughly 21% and the Netherlands' comparable range once vakantiegeld is included, largely because Japan's core social insurance rates (aside from pension) are somewhat lower and several components share caps rather than stacking uncapped like France's. Japan's distinctive twist is having two entirely employer-only line items, rousai hoken and the child/childcare levy, neither of which most other markets model as separate costs.
