Japan Power Harassment Prevention Law 2020: Employer Duties & Victim Remedies

• Three statutory harassment categories are illegal: Power Harassment (Labor Policy Comprehensive Promotion Act, Art. 31), Sexual Harassment (Equal Employment Opportunity Act, Art. 11), and Maternity/Paternity Harassment (Child Care and Family Care Leave Act, Art. 25).
• All employers — including SMEs — have been legally obligated to prevent harassment since April 1, 2022 (large companies: June 1, 2020). No "small business exemption" exists anymore.
• Foreign workers are protected identically to Japanese nationals. Visa status, language, or contract type (seishain / keiyaku / haken / part-time) does not reduce statutory protection.
• Victims have four parallel remedy tracks: (1) internal grievance desk, (2) Labor Bureau (Rōdōkyoku) free mediation, (3) Labor Tribunal (max 3 hearings, ~80 days), (4) civil litigation for damages and/or criminal complaint (assault Art. 204, threats Art. 222 of the Penal Code).
• Employer can be sued directly under "employer's vicarious liability" (Civil Code Art. 715) and "duty of safe-keeping" (Labor Contract Act Art. 5) — not just the individual harasser. Typical settlement range: JPY 500,000 – 5,000,000 plus lost wages.

Japan's 2020 Power Harassment Prevention Act (Labor Policy Act Art. 31) defines power harassment as conduct meeting three elements: superior position-based, beyond business necessity, and harmful to work environment. Six types: physical attack, psychological attack, social isolation, excessive demands, insufficient demands, and invasion of privacy. All employers must: establish anti-harassment policy, set up consultation systems, respond promptly to incidents, and protect privacy. Non-compliance leads to guidance, then public naming (Art. 33). Victim remedies: internal reporting, Labor Bureau consultation, workers' compensation (2023 reform added independent harassment category), and civil damages (tort Art. 709, employer liability Art. 715, duty of care Art. 5 Labor Contract Act).

• 1997: Equal Employment Opportunity Act amended to require sexual harassment prevention (employer "effort obligation").
• 2006: Sexual harassment prevention became a mandatory employer measure (EEOA Art. 11).
• 2016: Maternity harassment prevention added (EEOA Art. 11-3, Child Care Leave Act Art. 25).
• 2019: Labor Policy Comprehensive Promotion Act amended — power harassment provisions enacted.
• June 1, 2020: Power harassment prevention measures became mandatory for large companies.
• April 1, 2022: Power harassment prevention extended to all small and medium-sized enterprises (SMEs) — no more grace period.
• April 1, 2025: Tokyo Metropolitan Customer Harassment Prevention Ordinance entered into force (first in Japan).

A mid-30s engineer at a Tokyo IT firm was subjected to repeated public humiliation by his department head over an 8-month period. He developed an adjustment disorder, took 6 months of medical leave, and was certified for workers' compensation under the 2023 revised MHLW psychological-disorder recognition criteria. After filing through the Labor Bureau's mediation process and threatening a civil suit citing Civil Code Art. 709 (tort) and Art. 715 (employer's vicarious liability), the company agreed to a settlement of approximately JPY 3,200,000 plus full back pay, and the harasser received a formal disciplinary demotion.

A female contract employee at a manufacturing subsidiary reported that a male manager repeatedly made unwanted physical contact and sent suggestive LINE messages after work hours. Under EEOA Art. 11, the company's initial failure to take prompt measures triggered Labor Bureau guidance. After a proper internal investigation, the harasser was discharged for cause (chōkai kaiko). The victim additionally received JPY 1,500,000 in damages from the company under the duty-of-care theory (Labor Contract Act Art. 5).

A pregnant employee at a foreign-affiliated company in Osaka was told her "performance review would suffer" if she took statutory maternity leave, and was effectively demoted upon return. Under Child Care and Family Care Leave Act Art. 25 and EEOA Art. 11-3, any disadvantageous treatment because of pregnancy, childbirth, or childcare leave is presumed illegal. The Supreme Court's 2014 *Hiroshima Chuo Hoken Seikatsu Kyodo Kumiai* judgment established this near-strict-liability framework. Labor Tribunal concluded in three hearings (~75 days) with reinstatement, seniority restoration, and JPY 2,000,000 in compensation.

Q1. How do I collect evidence of workplace harassment in Japan? Preserve everything in writing: emails, chat logs (Slack/Teams/LINE), meeting minutes, and personnel actions. Audio recording without notifying the other party is legal in Japan for self-protection purposes (no two-party consent rule). Keep a contemporaneous diary noting date, time, location, witnesses, and exact words. Medical records and a psychiatric diagnosis are decisive for workers' compensation claims and damage quantification.

Q2. How much does it cost to hire a lawyer for a harassment case? Typical fee structures: (1) initial consultation JPY 5,500–11,000 per 30 minutes (many labor-side lawyers offer first session free); (2) retainer (chakushukin) JPY 200,000–400,000; (3) success fee (hōshukin) 10–20% of recovery. Legal Aid (Hōterasu) available below income threshold.

Q3. Can I consult a lawyer while still employed without being fired for it? Yes. Consulting a lawyer is a constitutional right (Art. 32). Retaliation against an employee for using statutory consultation channels is explicitly prohibited under Labor Policy Act Art. 30-2(2), EEOA Art. 11(2), and Child Care Leave Act Art. 25(2). Any subsequent dismissal, demotion, or assignment change becomes presumptively void.

Q4. Do these protections apply to foreign workers and non-Japanese-speaking employees? Yes, fully and equally. All three harassment statutes apply to "workers" without nationality, visa, or language qualifications. Multilingual Labor Bureau consultation is available — Tokyo, Osaka, Aichi, Kanagawa, Saitama, Chiba, Hyogo, and Fukuoka Labor Bureaus provide English, Chinese, Vietnamese, Portuguese, Tagalog, and other language support.

Q5. What happens if my employer retaliates against me after I make an internal report? Retaliation is an additional violation. Three statutory shields: (a) Whistleblower Protection Act (Kōekitsūhōsha Hogo-hō, 2022 amendment); (b) the harassment statutes' anti-retaliation clauses; (c) abuse-of-rights dismissal doctrine (Labor Contract Act Art. 16). Damages for retaliation typically run higher than for the underlying harassment.

Q6. Can harassment also be a criminal offense, not just civil? Yes, when conduct crosses statutory thresholds: assault (Penal Code Art. 208), bodily injury (Art. 204, including psychiatric injury such as PTSD per the Supreme Court's 2012 ruling), threats (Art. 222), intimidation/coercion (Art. 223), defamation (Art. 230), insult (Art. 231), and indecent assault (Art. 176). A criminal complaint (kokuso) runs in parallel to civil damages.

Q7. Is there a deadline / statute of limitations? Civil damages for harassment-related tort claims must be filed within 3 years from the date the victim knew of the damage and the perpetrator (Civil Code Art. 724), with an absolute cap of 20 years. For unpaid wages or labor-contract-based claims, the limitation is 5 years under the 2020 amended Labor Standards Act (transitional cap of 3 years until further notice).

Q8. What if the harassment is from a client or customer, not a colleague? This is "customer harassment" (kasu-hara). The employer still owes you a duty of care under Labor Contract Act Art. 5 and must take protective measures (e.g., reassignment, refusing service to abusive customers, security support). The Tokyo Metropolitan Customer Harassment Prevention Ordinance (effective April 1, 2025) makes Tokyo the first jurisdiction to legally require such measures.

1. Document everything (Week 0, ongoing) — Save emails, chats, recordings; maintain a dated diary; identify potential witnesses.
2. See a doctor if affected (Week 0-1) — Visit a psychiatrist or psychosomatic medicine clinic. Diagnosis is essential for both workers' comp and damages.
3. Use the internal consultation desk (Week 1-2) — All employers must have one (statutory obligation). Submit a written complaint; retain a copy. Demand a written response.
4. Consult the Labor Bureau (Week 2-4) — Free of charge. The Sōgō Rōdō Sōdan Coner at every prefectural Labor Bureau offers advice, employer guidance, and free mediation (assen).
5. Consult a lawyer (Week 3-6) — Especially before signing any settlement agreement (jidan-sho) or resignation letter.
6. File for workers' compensation if on sick leave — Through the local Labor Standards Inspection Office. The 2023 recognition standards explicitly list "power harassment" as an independent psychiatric-disorder recognition factor.
7. Labor Tribunal or lawsuit (Month 2-6) — Labor Tribunal: max 3 hearings, ~80 days; useful for monetary settlement. Full lawsuit: 12–24 months, used when seeking reinstatement or large damages.
8. Criminal complaint in parallel if applicable — File with the police via the prosecutor's office; can proceed simultaneously with civil action.
