What does it really cost to hire an employee in Japan in 2026?

Japan's employer cost breaks into three layers.

No statutory severance formula

Japan is unusual among major economies in having no statutory severance formula tied to years of service. The Labor Standards Act requires 30 days notice or pay in lieu of notice on dismissal. That is not severance. It is notice pay only. Voluntary retirement allowances (taishokukin) are common in Japanese practice and are contractual, but they are not mandated by law. Budget for them if your offer letter or the company rules promise them; otherwise, they are not a statutory cost.

Why the employer social total varies

Unlike countries with a fixed employer payroll tax rate, Japan's employer social insurance total varies because workers accident insurance rates differ by industry risk category, and nursing care insurance applies only to employees aged 40 to 64. For a Tokyo office employer with staff under 40, independent advisory sources put the combined employer social insurance total at approximately 14% to 16% of gross salary. For roles in higher-risk industries or for teams with a significant proportion of employees aged 40 to 64, the total is higher.

Japan's shakai hoken (social insurance) system splits responsibility across five branches. Welfare pension is the largest and most predictable line for the employer.

Why the total is not one clean number

Unlike welfare pension, the health insurance rate differs by insurer and prefecture. Tokyo employers using Kyokai-kenpo (the default managed health insurer) paid a total health insurance premium of 9.81% in 2026, split equally between employer and employee. Different prefectures have different Kyokai-kenpo rates. Large companies that operate their own kumiai-kenpo (health association) have their own premium rates. Employment insurance and workers accident insurance both vary by industry. This means no single employer social insurance total applies to all Japan employers in all industries.

Japan's leave entitlements are distinctive in two ways. Paid leave is earned, not given from day one. And sick pay comes from the health insurance fund, not the employer directly.

Annual paid leave

Under Labor Standards Act Article 39, employees become entitled to 10 days paid leave days after six months of continuous employment with at least 80% attendance. The entitlement increases with tenure:

From 2019, employers must ensure each employee takes at least 5 days of statutory leave per year. Failure to do so is a criminal offence under the Labor Standards Act.

Sickness and injury allowance

The employer does not fund short-term sick pay. The employee's health insurance pays a sickness and injury allowance (kenkohoken kyufkyufu). There is a waiting period of 3 days: payment starts from day four. The allowance is 66.67% of the employee's average daily standard remuneration. It continues for up to 18 months from the first payment date. Consecutive absences for the same condition aggregate toward the limit.

Maternity and paternity leave

Mothers are entitled to 14 weeks of protected leave (6 weeks before birth, 8 weeks after). The health insurance system pays a maternity allowance at approximately 67% of standard monthly remuneration. Because the benefit is tax-exempt and social insurance contributions are waived during leave, net replacement is closer to 80% of take-home pay.

Fathers can take up to 4 weeks of childcare-at-birth leave within 8 weeks of the birth. This leave was introduced under the October 2022 amendment to the Child Care and Family Care Leave Act. Pay during this leave comes from employment insurance, not the employer directly.

Two deductions reduce gross to net on the employee side: income tax (withholding tax withheld monthly by the employer) and the employee share of social insurance.

Income tax bands for 2026

Japan does not have a zero-rate band or a flat personal allowance. A basic deduction (kiso kojo) is subtracted from gross income before the bracket schedule applies. The deduction is JPY 1,040,000 for taxpayers with total income under JPY 4,890,000, phasing down progressively to zero above JPY 25,000,000. Because the deduction is tiered, not a clean single number, it must be described in prose rather than shown as a single figure token.

A reconstruction surtax of 2.1% applies on the national income tax liability across all bands. Combined with the 10% flat local inhabitant tax (jumin-zei), the effective all-in rate at the top band reaches approximately 56%.

Employee social insurance

The employee social insurance total is 14.69% of gross salary for workers under 40, comprising: health insurance 4.925%, child and childcare support 0.115%, welfare pension 9.15%, and unemployment insurance 0.5% (all 2026 rates per PwC Tax Summaries). Nursing care insurance adds 0.81% for employees aged 40 to 64. Welfare pension contributions are capped at a standard monthly remuneration of JPY 650,000 for regular salary.

This example uses a hypothetical gross monthly salary of JPY 500,000 (JPY 6,000,000 per year) and applies the verified statutory rates from the Japan compliance cache. All outputs are illustrative. Actual costs will differ based on your employee's health insurer, industry risk category, age, and whether any contractual retirement allowance applies.

These figures are illustrative. The welfare pension line (JPY 45,750) is derived as 9.15% of JPY 500,000. The gross of JPY 500,000 is below the monthly remuneration cap of JPY 650,000, so no cap applies to this example. The health insurance and employment insurance lines use approximate rates for a Tokyo office employer and a worker under 40; actual rates vary by insurer, prefecture, and industry classification. Nursing care insurance (approximately 0.81% employee and employer share each) is excluded because this example assumes an employee under 40.

No 13th-month salary requirement

Japan has no statutory 13th-month salary obligation. Summer bonuses (natsu no bofnus) and winter bonuses (fuyu no bofnus) are common practice in many industries and may form part of the expected total compensation package. They are contractual or customary, not mandated by law. Factor them in if your offer letter promises them or if you are hiring into an industry where bonus expectations are established.

Voluntary retirement allowance

Voluntary retirement allowances (taishokukin) are widespread in Japanese corporate culture. A company that has adopted taishokukin rules is typically bound to pay them on separation. There is no statutory formula: the amount and structure are set by each employer's internal rules. If you are hiring through an existing Japanese entity, check whether taishokukin rules apply before you model the true cost of employment.

1. Agree the gross monthly salary

   Confirm the gross monthly figure with the candidate. Japan pays monthly by law. Note the industry category, as it affects workers accident insurance rates.

2. Add welfare pension insurance

   Apply the employer pension rate to the gross monthly salary up to the standard monthly remuneration cap. This is the one fixed confirmed employer rate.

3. Add health, employment, and accident insurance

   Add the health insurance share (which varies by insurer and prefecture), the employment insurance share (which varies by industry), and the workers accident insurance rate for your industry risk category.

4. Check for nursing care insurance

   If any employee is aged 40 to 64, add nursing care insurance contributions to both the employer cost and the employee deductions.

5. Model leave and any contractual bonuses

   Factor in annual leave accrual, the health insurance allowance risk for extended sick leave, maternity and paternity leave cover, and any bonus commitments in the offer letter or company rules.

Real HR and legal experts handle your Japan hires, from the first offer letter through every gensen choshu (withholding tax) remittance, social insurance payment, and year-end salary adjustment (nencho seisan). An actual person, not a chatbot or a pooled queue. There is no setup fee and no exit fee. Employer cost passes through at cost, itemised on every invoice, so you see the pension line, the health insurance line, and the employment insurance line separately, never blended into an opaque margin.

EOR payroll, contractor onboarding, and entity setup all live on one platform. A Japan contractor who converts to payroll keeps their record. That same employee can graduate from EOR to your own Japan entity without switching systems. EOR is the right model for a first Japan hire, until it isn’t.
