Japan Labor Compliance Checklist for Foreign Companies: 20 Must-Know Requirements
Operating in Japan means navigating one of the world's most employee-protective labor law frameworks. For foreign companies establishing or expanding their presence in Japan, non-compliance isn't just a legal risk — it's a business risk that can derail operations, damage employer branding, and trigger costly disputes.
This guide provides a comprehensive checklist of 20 critical labor compliance requirements that every foreign company operating in Japan must know. Each item includes the legal basis, practical implications, and common pitfalls that foreign companies encounter.
Employment Foundation
1. Written Employment Contracts (Labor Standards Act, Art. 15)
Requirement: Employers must clearly state working conditions in writing at the time of hiring.
Must-include items: - Contract period (or confirmation of indefinite employment) - Place of work and scope of duties (including potential changes — added April 2024) - Working hours, breaks, holidays, and leave - Wages (calculation method, payment timing) - Retirement provisions
Common pitfall: Many foreign companies use their global employment agreement template translated into Japanese. This rarely covers all legally required items. Always have a Japan-qualified labor consultant (sharoushi) review your contract template.
2. Work Rules (Labor Standards Act, Art. 89)
Requirement: Workplaces with 10 or more employees must create and file Work Rules (shugyo kisoku) with the local Labor Standards Inspection Office.
Must-cover topics: - Working hours, breaks, holidays - Wages - Retirement and dismissal - Safety and health - Disciplinary actions
Common pitfall: Work Rules must be in Japanese and must be filed — not just created. They must also be communicated to all employees. Unfiled or uncommunicated Work Rules may not be enforceable in disputes.
3. Probation Period Limitations
Requirement: While probation periods are common (typically 3-6 months), termination during or at the end of probation requires nearly the same justification as regular dismissal.
Common pitfall: Foreign companies often assume probation works like "at-will employment." In Japan, once an employee has been hired, even during probation, dismissal requires objectively reasonable grounds.
Working Hours and Leave
4. Overtime Limits and the 36 Agreement (Labor Standards Act, Art. 36)
Requirement: To have employees work beyond the legal 8 hours/day or 40 hours/week, employers must conclude a labor-management agreement (the "36 Agreement") and file it with the authorities.
Absolute caps (since April 2019): - 45 hours/month, 360 hours/year (standard) - With special provisions: max 720 hours/year, 100 hours/month (including holiday work), 80 hours average over 2-6 months
Penalty: Up to 6 months imprisonment or a fine of up to 300,000 yen per violation.
Common pitfall: The 36 Agreement must be renewed annually. Forgetting to renew means any overtime is technically illegal.
5. Overtime Premium Pay (Labor Standards Act, Art. 37)
Requirement: Overtime work commands premium pay rates.
| Type | Premium Rate |
|---|---|
| Regular overtime | 25%+ |
| Overtime exceeding 60 hours/month | 50%+ |
| Holiday work | 35%+ |
| Late-night work (10 PM - 5 AM) | 25%+ |
Common pitfall: The 50% premium for overtime exceeding 60 hours/month has applied to SMEs since April 2023. Many smaller foreign offices in Japan are unaware of this change.
6. Annual Paid Leave — 5-Day Minimum (Labor Standards Act, Art. 39)
Requirement: Employees who have worked for 6 continuous months with 80%+ attendance receive 10+ days of paid leave. Employers must ensure at least 5 days are taken each year.
Penalty: Up to 300,000 yen per employee who fails to take 5 days.
Common pitfall: Even if your global policy provides generous PTO, you must separately track and enforce the Japanese statutory minimum. "Unlimited PTO" policies don't exempt you from the 5-day mandate.
7. Interval Rest Period (Effort Obligation)
Requirement: Employers should endeavor to ensure a rest period of a certain duration between the end of one workday and the start of the next (currently an effort obligation, not mandatory).
Why it matters: This is widely expected to become mandatory in future legislation. Forward-thinking companies are already implementing 11-hour intervals.
Social Insurance and Benefits
8. Social Insurance Enrollment (Health Insurance Act, Employees' Pension Act)
Requirement: Companies must enroll employees in health insurance (kenpo) and employees' pension insurance (kosei nenkin) from day one of employment.
Coverage: All regular employees, plus part-timers working 3/4+ of regular hours (or 20+ hours/week at companies with 51+ employees, effective October 2024).
Common pitfall: Some foreign companies delay enrollment during probation. This is illegal. Enrollment is mandatory from the first day of employment.
9. Employment Insurance (Employment Insurance Act)
Requirement: Employees working 20+ hours/week with expected employment of 31+ days must be enrolled in employment insurance.
Common pitfall: Part-time employees and contract workers often fall through the cracks. The threshold is 20 hours/week — not full-time status.
10. Workers' Compensation Insurance (Workers' Compensation Insurance Act)
Requirement: All businesses with even one employee must carry workers' compensation insurance. This covers work-related injuries, illnesses, and commuting accidents.
Key point: This is the employer's obligation and cost — it cannot be charged to employees.
Health and Safety
11. Annual Health Checkups (Industrial Safety and Health Act, Art. 66)
Requirement: Employers must provide annual health checkups to all regular employees.
Special requirements: - Night shift workers: checkups twice per year - Employees exposed to specific substances: special health checkups - Employees working 80+ overtime hours/month: offer of physician interview
Common pitfall: The cost must be borne by the employer. Employees must be paid for the time spent on health checkups during working hours.
12. Stress Check Program (Industrial Safety and Health Act, Art. 66-10)
Requirement: Annual stress checks are mandatory for all workplaces (expanded from 50+ employees to all workplaces starting 2026).
What it involves: - A standardized questionnaire (57 or 80 items) - Individual results reported to employees (NOT to employers without consent) - High-stress employees offered physician interviews - Group analysis for organizational improvement
Critical compliance point: Individual stress check results belong to the employee. The employer cannot access individual results without the employee's explicit consent. Violation of this rule is a serious breach.
Common pitfall: Many foreign companies treat stress checks as a mere checkbox exercise. The real value lies in the group analysis, which identifies organizational stress hotspots without revealing individual data.
13. Industrial Physician (Industrial Safety and Health Act, Art. 13)
Requirement: Workplaces with 50+ employees must appoint an industrial physician (sangyoi) who visits at least once per month.
Responsibilities include: - Reviewing health checkup results - Conducting interviews with high-stress employees - Advising on workplace environment improvements - Reviewing overtime records
Harassment Prevention
14. Power Harassment Prevention (Labor Policy Comprehensive Promotion Act)
Requirement: Since April 2022, ALL employers (including SMEs) must implement power harassment prevention measures.
Required measures: - Clear company policy against harassment - Consultation hotline/window - Prompt investigation and response procedures - Privacy protection for complainants - Prohibition of retaliation against complainants
Common pitfall: Having a policy in English only is insufficient. The policy and consultation procedures must be in Japanese and actively communicated to all employees.
15. Sexual Harassment and Maternity Harassment Prevention (Equal Employment Opportunity Act)
Requirement: Employers must take measures to prevent sexual harassment and maternity/paternity harassment (harassment related to pregnancy, childbirth, childcare leave, or nursing care leave).
Key point: This applies regardless of the gender of the victim or perpetrator, and includes same-sex harassment.
Termination and Restructuring
16. Dismissal Restrictions (Labor Contract Act, Art. 16)
Requirement: Dismissal must be based on objectively reasonable grounds and must be considered socially appropriate. Dismissal that lacks these elements is void.
The "four requirements" for economic dismissal: 1. Business necessity for workforce reduction 2. Sufficient effort to avoid dismissal (reassignment, voluntary retirement, etc.) 3. Reasonable selection criteria for those dismissed 4. Adequate explanation and consultation with employees/unions
Common pitfall: This is perhaps the single biggest culture shock for foreign companies. Japan does not have "at-will employment." Terminating an employee is extraordinarily difficult and requires extensive documentation and process.
17. Notice Period and Severance (Labor Standards Act, Art. 20)
Requirement: At least 30 days' advance notice or 30 days' average wages in lieu of notice.
Common pitfall: 30 days is the legal minimum, but in practice, mutual separation agreements with severance packages of 3-12 months' salary are standard for negotiated departures.
Data Protection and Privacy
18. Personal Information Protection (Personal Information Protection Act)
Requirement: Employers must specify the purpose of collecting employee personal information, use it only for that purpose, and implement appropriate security measures.
Key HR implications: - Health checkup results, stress check data, and disability information are "special care-required personal information" requiring explicit consent - Cross-border data transfer (e.g., to global HQ) requires specific safeguards - Employees have the right to request disclosure, correction, or deletion of their data
Common pitfall: Transferring Japanese employee data to overseas headquarters without proper consent and safeguards violates the Act.
19. My Number (Social Security and Tax Number)
Requirement: Employers must collect employees' My Number (individual identification number) for social insurance and tax purposes, and implement strict security measures for storage and handling.
Required safeguards: - Designated handler(s) - Physical and technical access controls - Destruction after the retention period - Employee training on handling procedures
Emerging Requirements
20. Equal Pay and Treatment for Non-Regular Workers (Part-Time and Fixed-Term Employment Act)
Requirement: Employers must not create unreasonable differences in treatment between regular and non-regular workers (part-timers, fixed-term, dispatched) performing similar work.
What counts as "unreasonable": - Base salary differences without objective justification - Exclusion from bonuses, retirement benefits, or allowances - Differences in training opportunities or welfare facilities
Common pitfall: Many foreign companies apply different benefit packages to contract employees vs. permanent employees without documenting the objective reasons for each difference. This is increasingly challenged in courts.

Beyond Compliance: From Obligation to Opportunity
Meeting Japan's labor compliance requirements is non-negotiable. But the smartest foreign companies operating in Japan go further — they use compliance as a springboard for building genuinely engaging workplaces.
Stress checks become a lens for organizational improvement. Overtime management becomes a catalyst for productivity enhancement. Harassment prevention training becomes a foundation for psychological safety. Each compliance requirement, when approached strategically, strengthens your ability to attract, retain, and develop talent in Japan's competitive labor market.
The companies that thrive in Japan are not those that treat compliance as a burden, but those that recognize it as an investment in their most important asset: their people.
