Workers Compensation Insurance in Japan: A Complete Guide for Foreigners

If you've been injured at work or during your commute in Japan, you're entitled to compensation through Japan's workers' accident compensation insurance system — regardless of your nationality. Known as Rousai Hoken (労災保険) or Industrial Accident Compensation Insurance, this mandatory government program protects all workers employed in Japan, from full-time office workers to part-time staff and temporary employees.

This guide explains everything you need to know about workers compensation in Japan as a foreigner: what it covers, how to file a claim, and what to do if your employer is uncooperative.

What Is Workers Compensation Insurance in Japan (Rousai Hoken)?

Workers' accident compensation insurance — commonly called Rousai — is a mandatory public insurance system administered by the Japanese government under the Ministry of Health, Labour and Welfare (MHLW). It provides medical care and financial compensation to workers who are injured, become ill, disabled, or die as a result of work duties or commuting.

Key points:

• Applies to ALL businesses that employ even one worker
• Covers ALL employees regardless of nationality, visa status, or employment type
• Employers pay 100% of premiums — workers pay nothing out of pocket
• Managed through the local Labor Standards Inspection Office (Rodo Kijun Kantokusho / 労働基準監督署)

The system is separate from Japan's general health insurance (Kenko Hoken). When a work-related injury or illness occurs, Rousai Hoken — not your health insurance — covers the costs.

Who Is Covered Under Japan's Workers Compensation System?

One of the most important things to understand is that Rousai Hoken applies to all workers in Japan, regardless of nationality. As a foreigner working legally (or even illegally, in practice) in Japan, you have the same rights as Japanese employees when it comes to workplace injury compensation.

Workers Covered

• Full-time regular employees
• Part-time workers
• Fixed-term contract workers
• Temporary/dispatched workers (haken)
• Foreign nationals on work visas
• Foreign students working part-time jobs

Workers Generally NOT Covered

• Self-employed individuals and sole proprietors (voluntary enrollment is available for some)
• Government/public sector workers (they have a separate system)
• Family members working informally in a family business

If your employer tries to tell you that you're not covered because you're a foreigner — that is incorrect. The law clearly states that the Industrial Accident Compensation Insurance Act applies to foreign nationals working in Japan as employees.

What Does Rousai Hoken Cover?

Japan's workers compensation insurance covers a comprehensive range of situations and provides seven main types of benefits:

Work Accidents vs. Commuting Accidents

Rousai Hoken covers both:

Work accidents (Gyomu Saigai / 業務災害): Injuries or illnesses that occur during the performance of your job duties. This includes injuries on work premises, occupational diseases from prolonged exposure, and mental health conditions caused by overwork or harassment.

Commuting accidents (Tsuko Saigai / 通勤災害): Injuries that occur while traveling between your home and workplace, using a "reasonable and normally accepted route and method." Note that if you make significant detours for personal errands, that portion of the commute may not be covered.

How Much Compensation Will You Receive?

The compensation amounts under Rousai Hoken are calculated based on your average daily wage (Kyufu Kiso Nichigaku / 給付基礎日額).

Temporary Absence Benefit (休業補償給付)

When you cannot work due to a work-related injury or illness:

• Days 1–3: Your employer must pay 60% of your average wage directly (this is the "waiting period")
• Day 4 onward: Rousai Hoken pays 60% of your average daily wage + a special additional benefit of 20% (totaling 80% in practice)

Medical Benefits

• Treatment at designated industrial accident hospitals: Completely free with no co-payment required
• Treatment at non-designated hospitals: You may need to pay upfront and claim reimbursement

Disability Benefits

If you suffer permanent disability, compensation is categorized into 14 disability grades, ranging from Grade 1 (most severe) to Grade 14 (least severe). Grades 1–7 receive a pension; Grades 8–14 receive a lump sum payment.

How to File a Workers Compensation Claim in Japan

If you've been injured at work or during your commute, follow these steps to file a Rousai Hoken claim:

Step 1: Seek Medical Treatment Immediately

Go to a hospital — ideally a designated industrial accident hospital (Rousai Shitei Byoin). At a designated facility, you receive treatment free of charge by presenting your employer information. If you go to a non-designated hospital, you may need to pay and then claim reimbursement.

Step 2: Report to Your Employer

Inform your employer about the accident as soon as possible. Your employer is legally required to help you complete the necessary paperwork and submit it to the Labor Standards Inspection Office.

Step 3: Complete the Claim Forms

The required forms differ based on the type of benefit:

• Form 5 (Dai 5 Go Yoshiki): Medical treatment at a designated hospital
• Form 7 (Dai 7 Go Yoshiki): Medical treatment at a non-designated hospital (for reimbursement)
• Form 8 (Dai 8 Go Yoshiki): Temporary absence compensation

Forms are available at the Labor Standards Inspection Office or can be downloaded from the MHLW website.

Step 4: Submit to the Labor Standards Inspection Office

Your employer typically submits the forms on your behalf. However, if your employer refuses to cooperate, you can submit the claim yourself directly to the Labor Standards Inspection Office. You do not need your employer's signature to initiate a claim.

Step 5: Investigation and Payment

The Labor Standards Inspection Office will investigate whether the incident qualifies as work-related. If approved, benefits are paid directly to you or the medical institution.

What If Your Employer Refuses to Help?

This is unfortunately a common issue, especially for foreign workers. Some employers — particularly in smaller companies or industries with many foreign workers — may refuse to acknowledge a workplace accident or pressure you not to file a claim. Here's what you can do:

1. File the claim yourself. You do not need your employer's cooperation to file a Rousai claim. You can go directly to the Labor Standards Inspection Office and submit the forms yourself.

2. Contact the Labor Standards Inspection Office. They can advise you on how to proceed and may investigate your employer if there is non-compliance.

3. Consult a labor union or legal aid organization. Many unions and non-profit organizations in Japan provide free consultation for foreign workers facing labor issues.

4. Contact the General Union or your country's embassy. These organizations can often provide advice and support in your language.

Special Considerations for Foreign Workers in Japan

Foreign workers face some unique challenges when dealing with Japan's workers compensation system:

Language Barriers

The claim forms and procedures are primarily in Japanese. While the MHLW has created multilingual guides for foreign workers, the process can still be confusing. The official guide is available in English, Chinese, Vietnamese, Indonesian, Tagalog, and other languages at the MHLW website.

Visa Status and Compensation

Your workers compensation rights are not affected by your visa status. Even if you are working in a status that may not be fully authorized, you still have rights to medical treatment and compensation under Rousai Hoken.

Sending Compensation Overseas

If you return to your home country during recovery or after disability, it is possible to receive ongoing Rousai benefits sent internationally. Discuss this with the Labor Standards Inspection Office when filing your claim.

Totalization Agreements

Japan has totalization agreements with various countries (including the US, UK, Germany, and others) to prevent double social insurance contributions. However, these agreements generally do not affect Rousai Hoken coverage, which remains mandatory for all workers in Japan.

Rousai Hoken vs. Regular Health Insurance: Key Differences

Many foreigners are confused about when to use Rousai Hoken versus their regular health insurance (Kenko Hoken). The rules are clear:

Important: Using your regular health insurance for a work-related injury is technically incorrect. If discovered, the health insurer can request reimbursement, and you may face complications. Always use Rousai Hoken for anything work-related.

Voluntary Rousai Enrollment for Self-Employed Workers

If you are self-employed or a sole proprietor (freelancer), you are not automatically covered by Rousai Hoken. However, certain categories of self-employed workers can voluntarily enroll in a special scheme called Tokubetsu Kanyū (特別加入).

Eligible groups for voluntary enrollment include:

• Construction subcontractors and sole proprietors in certain industries
• Workers at small businesses owned by the proprietor themselves
• Specific types of agricultural workers
• Some IT freelancers and delivery workers (added in recent years)

The premiums for voluntary enrollment are calculated based on a chosen daily wage amount and the industry-specific insurance rate.
