In Japan, dismissing an employee is subject to a high level of legal scrutiny shaped by long-standing judicial doctrine. Employers must support any termination with compelling, well-documented reasons as part of broader global compliance obligations and follow a process that meets established standards of fairness. If these expectations are not met, courts may invalidate the dismissal entirely, often requiring reinstatement with back pay rather than awarding damages.
Japan does not permit at-will dismissal. The Labor Contract Act (Article 16) and the Labor Standards Act (Article 20) establish one of the most employee-protective dismissal frameworks among developed economies. Japanese courts go beyond reviewing terminations. They will nullify them if the employer cannot demonstrate objectively reasonable grounds and procedurally appropriate conduct.
This guide covers the legal framework, mandatory notice requirements, severance practices, a step-by-step offboarding checklist, and how Multiplier manages compliance.
Termination laws in Japan
Japan does not follow an at-will employment system. Employers cannot terminate employees freely; dismissals must have objectively reasonable grounds and be socially acceptable. This means valid reasons, fair process, and proper notice or payment in lieu are required.
If these are not met, courts often invalidate the dismissal, leading to reinstatement with back pay. The framework is governed by the Labor Contract Act of Japan and the Labor Standards Act of Japan, with strict standards on abusive dismissal.
In practice, most employers use mutual separation agreements to reduce risk.
Termination at-will vs. just cause
Japan does not permit at-will termination. Under Article 16 of the Labor Contract Act, a dismissal lacking objectively reasonable grounds and not appropriate in light of socially accepted norms is an abuse of the right to dismiss and is void. A termination without sufficient grounds is legally null from day one.
Governing law
Two core employment laws govern dismissal in Japan:
- Labor Contract Act (LCA), Article 16: Establishes the abuse of rights doctrine. Any dismissal lacking objectively reasonable grounds is automatically invalid.
- Labor Standards Act (LSA), Article 20: Requires a minimum of 30 days’ advance notice or payment in lieu.
Probationary period
Most probationary periods in Japan run between three and six months, with a legal maximum of one year.
Termination during this period is somewhat more flexible, but not at-will:
- Employers must still show objectively reasonable grounds (e.g., skill gaps or misrepresentation)
- Courts recognize probation as evaluative, but still require justification
One critical rule:
- Employees who have worked 14 days or more are entitled to 30 days’ notice
- Dismissal within the first 14 days requires no notice
How Multiplier handles termination and offboarding in Japan
Termination in Japan is high-risk and closely scrutinized. Multiplier manages the process end-to-end to ensure compliance.
When you submit a termination request:
- Legal review: Our in-country experts assess whether the case meets the Article 16 standard before any employee communication
- Risk classification: We determine if the case qualifies as dismissal with cause, without cause, or mutual separation
- Strategy guidance: We advise on mutual separation where legal grounds are uncertain
- Documentation: We prepare compliant termination notices in Japanese
- Final settlement: We manage severance, final pay, and offboarding in line with legal requirements
No communication is made to the employee until the compliance review is complete, reducing legal risk.
Types of termination
How you end an employment relationship in Japan matters; the rules, risks, and outcomes vary significantly by type.
Voluntary resignation
Employees who resign must give at least two weeks’ notice under the law, though most companies require 30 days.
The resignation must be documented in writing. Employers cannot withhold final pay due to an informal or verbal resignation.
Employees are entitled to:
- Outstanding salary
- Accrued unused leave
Involuntary termination with cause (disciplinary dismissal / Chokai Kaiko)
A just-cause dismissal applies only in cases of serious misconduct.
This may include:
- Fraud or criminal conduct
- Significant breach of company policy
- Disclosure of confidential information
The threshold is high. The employer must show:
- Serious misconduct
- Proper procedure followed
Because courts apply strict standards, weak cases are often invalidated.
Involuntary termination without cause (ordinary dismissal / Futsu Kaiko)
Dismissal for performance or incapacity requires strong procedural steps.
Employers must demonstrate:
- Documented warnings
- A genuine opportunity to improve (typically via a PIP)
- Consideration of alternative roles before dismissal
Courts expect clear evidence that dismissal was a last resort.
Redundancy (Seiri Kaiko)
Redundancy dismissals must meet strict judicial criteria.
Employers must demonstrate:
- Genuine business need to reduce headcount
- Exhaustion of alternatives (e.g., transfers, reduced hours, hiring freeze)
- Objective and fair selection criteria
- Proper explanation and consultation with employees or unions
Offering voluntary retirement with enhanced severance is standard practice to reduce risk.
Mutual separation agreement
This is the most common and practical route in Japan.
Because unilateral dismissal is difficult, employers often agree on mutual separation terms.
Key features:
- Agreed termination date
- Negotiated severance (often enhanced)
- Lower legal risk compared to unilateral dismissal
Mandatory notice periods
Statutory notice is governed by 30 days’ minimum notice.
Employers must provide:
- 30 days’ notice, or
- Payment in lieu of notice
Contractual notice periods may be longer but cannot be shorter than the statutory minimum.
Notice period rules by length of service in Japan
Use the table below to verify your obligations before issuing any termination communication:
Length of service | Employer notice period | Employee notice period | Payment in lieu permitted? | Notes |
First 14 days of employment (including probation) | None required | None required | N/A | Only window where notice-free dismissal is lawful under LSA Article 21 |
14 days to end of probation | 30 days or 30 days’ pay in lieu | 2 weeks (Civil Code) | Yes | After day 14, full LSA Article 20 applies regardless of probation status |
Less than 1 year (post-probation) | 30 days or 30 days’ pay in lieu | 2 weeks (Civil Code) | Yes | Work rules may specify longer employee notice |
1 to 5 years | 30 days or 30 days’ pay in lieu | 30 days (if specified in work rules) | Yes | Many companies set a 30-day employee notice period in their company rules |
5 to 10 years | 30 days or 30 days’ pay in lieu | 30 days (if specified in work rules) | Yes | Senior roles often have contractually longer periods |
10+ years | 30 days or 30 days’ pay in lieu | 30 days (if specified in work rules) | Yes | Employees within protected categories cannot be dismissed regardless of tenure |
Japan’s employer notice period is a flat 30 days across all tenures. What changes with tenure is protected status and the practical expectation that mutual separation replaces unilateral dismissal for long-serving staff.
Severance pay and redundancy
Japan does not have a statutory severance requirement beyond 30 days’ notice or payment in lieu. However, many employers provide severance pay through a retirement allowance (taishokukin) system.
Once included in company work rules or an employment contract, this becomes legally enforceable and must be paid as defined.
Eligibility
Severance is typically owed when:
- An employee is terminated without cause, or
- A voluntary resignation or mutual separation includes severance under company policy
Severance is generally not paid in cases of disciplinary dismissal.
Calculation formula
There is no statutory formula for severance.
Most companies follow an internal structure:
- Base salary multiplier based on years of service
- Common approach: ~one month’s salary per year of service
- Adjustments may apply based on tenure and reason for exit
If a formula is defined in work rules or contracts, it is binding and cannot be reduced unilaterally.
Retirement allowance mechanism
Employers may maintain a retirement allowance system as part of their broader employee benefits and compensation framework.
Key features:
- Applies mainly to permanent employees
- Accrues over tenure
- Paid as a lump sum upon exit (depending on company rules)
This system is widely used but not legally mandatory unless contractually agreed.
Taxation
Severance (retirement allowance) in Japan receives favorable tax treatment:
- Taxed separately from regular employment income
- Retirement Income Deduction applies:
- ¥400,000 (≈ $2,650–$2,700) per year (first 20 years)
- ¥700,000 (≈ $4,650–$4,700) per year (beyond 20 years)
- The remaining taxable amount is halved before tax is applied
This makes severance relatively tax-efficient, especially for long-tenured employees.
Employee offboarding checklist for Japan
Japan requires more documentation at termination than most jurisdictions. Missing any of the following steps creates legal exposure. Work through this list sequentially:
Step 1: Termination or resignation notice
All terminations must be documented in writing, in Japanese, with grounds clearly stated. For disciplinary dismissals, cite the specific conduct and applicable company rule. For mutual separations, both parties must sign a mutual termination agreement (合意退職書).
Step 2: Labor union or employee representative notification
Where a labor union exists, consult before proceeding with redundancy or economic dismissals. Skipping this increases tribunal risk significantly.
Step 3: Exit interview and handover
Conduct a structured handover covering active work, client relationships, system access, and documentation. Record it in writing, signed by both parties.
Step 4: Equipment return
Retrieve all company-owned assets and issue a written receipt confirming return. Document any outstanding items.
Step 5: IT access revocation
Revoke all system access, email accounts, VPN credentials, and application logins on or before the last working day.
Step 6: Final documents
Issue a certificate of employment (離職票, rishoku-hyo), required for unemployment insurance claims through Hello Work. Also, issue a withholding tax certificate (源泉徴収票) for the tax year.
Step 7: Social insurance deregistration
Notify social insurance and pension bureaus to terminate contributions and transfer records within five days of the separation date.
Final pay and settlement
Timing for payroll and final settlement is regulated under the Labor Standards Act of Japan. Delays or incorrect payments can lead to labor disputes and penalties.
Timeline
All final pay must be processed:
- Within seven days of the employee’s request, or
- On the next regular payday, whichever comes first
This applies to all termination types.
Unused leave (Mandatory payout)
Accrued annual leave must always be paid out at termination, including:
- All unused statutory leave
- Paid at the employee’s daily wage rate
Unused leave cannot be forfeited under any termination scenario.
Permissible deductions
Employers may deduct only:
- Statutory deductions (tax, social insurance, etc.)
- Deductions explicitly agreed in the employment contract
- Unauthorized deductions are considered a labor law violation.
Why this matters
Japan strictly enforces wage payment rules. Delays, underpayment, or improper deductions can quickly escalate into formal claims or labor tribunal proceedings.
Wrongful dismissal protections
Japanese law provides strong protection against unfair dismissal. Terminations that do not meet legal standards are often deemed invalid.
Protected categories
Under Article 19 of the Labor Standards Act of Japan, the following employees cannot be dismissed:
- Employees on leave due to work-related injury or illness (plus 30 days after return)
- Employees on maternity leave (plus 30 days after return)
- Employees on childcare or family care leave
Consequences of wrongful dismissal
If a dismissal is found invalid under the Labor Contract Act of Japan, courts may order:
- Reinstatement to the original role, or
- Back pay covering the full period since dismissal
Back pay typically covers six to eighteen months. Most cases settle through labor tribunals with a lump-sum payment, but there is no strict time limit for employees to challenge dismissal.
How Multiplier handles termination in Japan
Japan’s labor laws create a high-risk environment for employers, especially those used to at-will systems where termination is straightforward.
In Japan, the same action requires objectively reasonable grounds, careful documentation, proper notice, and often a mutual separation approach to avoid invalid dismissal claims.
Multiplier’s employer of record (EOR) service manages the entire termination process. Our Japan-based legal team reviews each request, confirms whether it meets the standards under the Labor Contract Act of Japan, and advises on the safest path forward, including mutual separation where required.
We assess the legal basis, prepare termination notices or separation agreements in Japanese, calculate any applicable severance or retirement allowance, and process final pay and unused leave encashment in line with the Labor Standards Act of Japan.
We also handle key offboarding steps, including issuance of the rishoku-hyo (separation certificate), social insurance deregistration, tax documentation, and coordination of equipment return.
If a labor dispute arises, our in-country team manages the response and supports resolution through labor tribunals or courts.
Companies using Multiplier avoid the most common risks in Japan, such as invalid dismissals, lack of proper documentation, failure to follow procedural steps, and mishandling of final pay and severance. The process is managed end-to-end; you make the business decision, and we handle the legal execution.

FAQs
Can I terminate an employee on sick leave in Japan?
No. Employees absent due to work-related injury or illness cannot be dismissed during their medical leave period or within 30 days after return, an automatic violation under Article 19. For non-work-related illness, the statutory medical leave period must typically expire before termination is permissible.
Is a verbal resignation legally binding in Japan?
Technically, yes, under the Civil Code, it can take effect two weeks after it is given. But verbal resignations create significant documentation risk. Always require written notice and confirm receipt to protect against later claims of resignation under duress.
How is severance calculated for part-time workers?
Part-time employees are generally not covered by a company's retirement allowance system unless work rules explicitly include them. Where included, the same formula applies to pro-rated hours or base salary.
What happens if I cannot prove the grounds for termination in a labor tribunal?
The tribunal declares the dismissal void under Article 16. The employee is entitled to reinstatement plus back pay for the full period from dismissal to the decision, typically six to eighteen months. The Labor Tribunal process is completed within approximately three months.
Is it better to pursue mutual separation than unilateral dismissal in Japan?
Almost always yes when grounds are contested or borderline. Mutual separation eliminates the abuse of rights risk and creates certainty for both parties. The cost of an enhanced severance package is nearly always lower than losing a tribunal case.
