Statutory employer costs in Japan
In Japan, employer social-insurance contributions total roughly 15.5% of monthly remuneration up to the standard remuneration ceiling (approximately ¥16.32M/yr): kosei nenkin pension ~9.15%, health insurance ~5%, unemployment insurance ~0.95%, plus workers' compensation (~0.3%–1.3% by industry). Above the cap only labor insurance continues (~3%). Customary summer and winter bonuses raise effective annual cost by ~17%, costed via 14 pay periods.
| Contribution | Employer rate | Notes |
|---|---|---|
| Kosei nenkin (employee pension) | 9.15% | Capped at standard remuneration of ¥650,000/month for pension. Employer and employee split equally. |
| Health insurance (kenko hoken) | ~5.0% | Rate varies by Kyokai Kenpo prefecture (Tokyo ~4.99%). +0.91% for kaigo hoken (long-term care) for employees aged 40–64. |
| Unemployment insurance (koyo hoken) | 0.95% | 0.6% general business; agriculture/construction higher. |
| Workers' compensation (rosai) | 0.25–8.8% | 100% employer-funded. Office work ~0.25%, construction high. Capped at salary, no upper limit. |
Mandatory employee benefits
Beyond statutory contributions, Japan law requires the following benefits the employer must fund.
- Annual leave (yukyu kyuka)
- 10 days from month 6, rising 1 day/yr to 20 days at 6.5 years. Five mandatory paid days must be taken per year (Work Style Reform 2019).
- Bonuses (shoyo)
- Not statutory but customary: ~2 months in summer (June) + ~2 months in winter (December). Skipping them signals an unstable employer.
- Commuting allowance (tsukin teate)
- Not statutory but near-universal; tax-free up to ¥150,000/month.
- Retirement allowance (taishokukin)
- Lump sum on resignation/retirement, calculated as base × tenure × coefficient. Contractual but expected for 3+ years of tenure.
Termination, notice and severance
Probation
Standard 3 months (shiyo kikan). Dismissal during probation still requires 'objectively reasonable grounds' under Labor Contract Act Art. 16.
Notice period
30 days statutory under Labor Standards Act Art. 20, OR 30 days' pay in lieu. Combinations allowed (e.g. 15 days notice + 15 days pay).
Severance
No statutory severance. But unjust dismissal under LCA Art. 16 typically results in reinstatement + back pay (6–24 months) or a negotiated settlement of 6–24 months' salary. Mutual-agreement separations (taisyoku gankokyu) are the norm; expect to pay 3–12 months as 'settlement money' even for cause.
Common compliance pitfalls
- At-will termination is functionally illegal. The Tokyo labor tribunal applies the 'four requirements' (necessity, effort to avoid dismissal, fair selection, proper procedure) and rejects most foreign-led firings. Budget for negotiated exit packages.
- Standard remuneration (hyojun hoshu gakkyu) for social insurance is recalculated each September from April–June average pay — promotions or bonus restructuring mid-year can shift contribution brackets unexpectedly.
- Bonuses are 'discretionary' in the contract but customary in practice. Cutting them after a hiring round triggers wrongful-treatment claims (futo rodo koi).
- Permanent establishment (PE) risk is high: an employee with contract-signing authority in Japan can trigger corporate income tax exposure for the foreign HQ within 6 months. Confirm EOR's PE indemnification before signing.
