Japan's Power Harassment Prevention Act: What Every Worker Needs to Know

Since April 2022, every business in Japan — from multinational corporations to small family-run shops — has been legally required to implement measures preventing power harassment (パワハラ, "pawahara"). The amended Act on Comprehensive Promotion of Labor Policies has fundamentally changed workplace dynamics across the country.

Yet despite the law being in effect for years, many workers and employers still struggle to understand what constitutes power harassment, what obligations employers carry, and how victims should respond. This guide breaks it all down.

What Is the Power Harassment Prevention Act?

The law, formally known as the Act on Comprehensive Promotion of Labor Policies (労働施策総合推進法), was amended in 2019 and took effect for large enterprises in June 2020. Since April 2022, it applies to all businesses in Japan, including small and medium enterprises.

Timeline	Milestone
May 2019	Amendment passed by the Diet
June 2020	Effective for large enterprises (301+ employees)
April 2022	Extended to all businesses

The Ministry of Health, Labour and Welfare (MHLW) receives over 80,000 consultations annually related to workplace bullying and harassment — underscoring why this legislation was necessary.

The 3 Criteria for Power Harassment

The MHLW defines power harassment as conduct meeting all three criteria:

1. Based on a superior position — Not limited to boss-subordinate relationships. It includes colleagues with specialized knowledge or group-based pressure.
2. Beyond what is necessary and appropriate for work — Exceeds legitimate business instruction.
3. Harms the worker's working environment — Causes physical or psychological distress that makes it difficult to perform duties.

The 6 Types of Power Harassment

1. Physical Attack (身体的攻撃)

Hitting, kicking, throwing objects. Even a "light tap" can qualify.

2. Psychological Attack (精神的攻撃)

Verbal abuse, humiliating someone in front of colleagues, prolonged harsh scolding. Phrases like "You're useless" or "Just quit" are textbook examples.

3. Isolation (人間関係からの切り離し)

Deliberately excluding someone from meetings, chat groups, or information sharing. In remote work settings, this includes removing someone from Slack channels or video calls.

4. Excessive Demands (過大な要求)

Assigning clearly impossible tasks or work that has nothing to do with someone's role. Expecting a new hire to perform at senior level is a common example.

5. Insufficient Demands (過小な要求)

Giving someone work far below their capabilities, or giving them no work at all. The classic "window seat" (窓際族) treatment of sidelining managers to do menial tasks.

6. Invasion of Privacy (個の侵害)

Prying into personal life — persistently asking about romantic relationships, monitoring social media, or disclosing someone's sexual orientation, medical history, or family situation to others.

Employer Obligations Under the Law

Companies must implement four categories of measures:

1. Clear Policy & Education

• Explicitly state in work rules that power harassment is prohibited
• Conduct training for all employees, including management

2. Establish Consultation Channels

• Set up internal and/or external consultation desks
• Ensure staff are trained to handle reports appropriately

3. Swift Post-Incident Response

• Investigate facts promptly
• Provide relief to victims (transfers, mental health support)
• Take disciplinary action against perpetrators

4. Privacy Protection & Anti-Retaliation

• Protect the privacy of both parties
• Prohibit any adverse treatment of those who report harassment

Penalties for Non-Compliance

While the law doesn't impose direct criminal penalties, non-compliant employers face:

• Administrative guidance (助言・指導・勧告)
• Public disclosure of company name for refusing to comply with recommendations
• Fines up to ¥200,000 for refusing to report to authorities

Beyond administrative measures, harassment itself can lead to civil liability — victims can sue for damages, and companies can be held liable for negligence in their duty of care.

How to Respond If You Experience Power Harassment

Step 1: Document Everything

Evidence is critical. Record:

• Date, time, location, and circumstances — be specific
• Exact words spoken — quote directly when possible
• Witnesses present
• Audio recordings — recording your own conversations is legal in Japan
• Screenshots of emails, messages, or chats

Storing evidence securely matters. Company devices may become inaccessible if you leave. Tools like LOCK.PUB allow you to save harassment records in encrypted, password-protected memos or chat rooms that you can share selectively with trusted people, lawyers, or labor authorities.

Step 2: Use Internal Channels

Report to your company's harassment consultation desk. The law requires employers to protect your privacy and prohibits retaliation for filing a report.

Step 3: Contact External Authorities

If internal channels fail, turn to:

Resource	What They Do
Prefectural Labor Bureau (都道府県労働局)	Administrative guidance, mediation
General Labor Consultation Corner (総合労働相談コーナー)	Free consultation on all labor issues
Japan Legal Support Center (法テラス)	Legal referrals
Labor attorney	Lawsuits, labor tribunal representation

Step 4: Secure Your Records

Throughout the process, keep your evidence safe. Using LOCK.PUB's encrypted memo feature, you can store dated records with password protection — ready to share when needed for legal proceedings or administrative complaints.

Legitimate Guidance vs. Power Harassment

Legitimate Guidance	Power Harassment
Points out specific improvements	Attacks personality
Done privately	Done publicly to humiliate
Related to work duties	Involves personal life
Gives chance to improve	Corners the person
Considers the worker's situation	Ignores ability or context

Conclusion

Japan's Power Harassment Prevention Act gives every worker legal backing to demand a harassment-free workplace. Understanding the six types, knowing your rights, and documenting incidents properly are the most powerful tools available.

If you're experiencing harassment, start by contacting the General Labor Consultation Corner — it's free, available at every prefectural labor bureau, and confidential. And consider using encrypted tools like LOCK.PUB to keep your records safe and shareable when the time comes.
