Stress Check in Japan: Complete Employer's Guide to Legal Compliance and Implementation
Introduction
If you manage HR or operations for a company with employees in Japan, you are likely subject to Japan's mandatory stress check program (ストレスチェック制度). Since its introduction in 2015 under the Industrial Safety and Health Act (労働安全衛生法), the stress check has become a cornerstone of workplace mental health management for companies operating in Japan.
This guide covers everything an HR manager needs to know: legal obligations, implementation roles, timelines, reporting requirements, and how to handle employees who don't speak Japanese — all in a format accessible to non-Japanese-speaking HR teams.
1. What Is the Stress Check Program?
The stress check program is a mandatory annual survey that helps employees self-assess their stress levels. It is governed by Article 66-10 of the Industrial Safety and Health Act.
Key points:
- Employees complete a questionnaire to identify their own stress status
- Results are sent directly to the employee — the company cannot see individual results without the employee's explicit consent
- If an employee is flagged as "high-stress," they may request an interview with a company-designated physician
- Companies use aggregated group analysis data (not individual data) to improve working conditions
Who must implement it?
| Company Size | Obligation |
|---|---|
| 50+ employees at a single workplace | Mandatory (annual, with reporting to Labor Standards Inspection Office) |
| Under 50 employees | Best-effort basis (mandatory from 2028 onwards) |
Note: "Employees" counts all workers at a single workplace (事業場) regardless of employment type, including full-time, part-time, and fixed-term contract employees. Foreign national employees are included regardless of visa type.
2. Legal Obligations for Employers
As the employer (事業者), your obligations under the law include:
- Annual implementation — once per year, per workplace (事業場)
- Cost coverage — the cost of the stress check must be borne by the employer, not the employee
- Reporting to Labor Standards Inspection Office — workplaces with 50+ employees with a designated industrial physician must file an annual report by end of March each year
- Prohibition on adverse treatment — you cannot penalize employees for not taking the test, for their results, or for requesting an interview with a physician
- Information management — individual results must be stored securely for 5 years
What the company CAN and CANNOT do:
| Action | Allowed? |
|---|---|
| Knowing that an employee took the test | ✅ Yes (participation records) |
| Seeing an individual employee's result | ❌ No (without written consent) |
| Using group analysis data for workplace improvement | ✅ Yes |
| Penalizing an employee who refuses to take the test | ❌ No |
| Penalizing an employee based on their result | ❌ No |
3. Implementation Structure: Who Does What
The stress check requires three distinct roles, each with different responsibilities:
Role 1: Implementer (実施者)
The implementer is the licensed professional responsible for conducting the stress check. They must hold one of the following qualifications:
- Physician (including industrial physician)
- Public health nurse (保健師)
- Psychiatric social worker (精神保健福祉士)
- Nurse (with required training completion)
- Certified social insurance and labor advisor (社会保険労務士, with required training)
The implementer's duties include: - Selecting the questionnaire - Determining criteria for high-stress designation - Evaluating and notifying employees of their results - Conducting or arranging interviews for high-stress employees - Providing group analysis to the employer
Important: The implementer must be independent from management. HR directors or managers cannot serve as the implementer.
Role 2: Administrative Staff (実施事務担当者)
This is typically an HR or general affairs staff member. No license required. They handle: - Notifying employees and distributing access to the questionnaire - Managing employee lists and system registration - Following up on non-respondents - Storing results (without accessing individual content)
Important: Administrative staff cannot view individual results. Only the implementer can access individual data.
Role 3: Industrial Safety and Health Committee (衛生委員会)
Companies with 50+ employees must have a health and safety committee. This committee: - Deliberates and approves the annual implementation policy - Reviews group analysis results - Proposes workplace improvement measures
4. Questionnaire Options
The Ministry of Health, Labour and Welfare (MHLW) provides two standard questionnaires:
| Questionnaire | Items | Recommended For |
|---|---|---|
| 57-Item Version | 57 questions | Most companies. Enables comparison with national benchmark data |
| 80-Item Version | 80 questions | Organizations wanting more detailed measurement of supervisor/colleague support |
For most employers, the 57-item version is recommended as a starting point. It produces nationally comparable data and requires less time for employees to complete.
5. Annual Timeline
A typical implementation cycle for companies running their stress check in October:
| Month | Action |
|---|---|
| June | Health & Safety Committee deliberates and approves implementation policy |
| July | Select and contract an external provider (if outsourcing) / Draft internal regulations |
| August | Notify all employees — explain anonymity, prohibition on adverse treatment |
| September | System setup, register employee list |
| October | Conduct stress check (allow 3–4 weeks for completion) |
| November | Compile results, notify high-stress employees of interview option |
| December | Receive group analysis report, present to Health & Safety Committee |
| January | Plan and implement workplace improvements based on group analysis |
| By end of March | File annual report to Labor Standards Inspection Office (if required) |
6. Handling Multilingual Workforces
If your company employs foreign nationals who are not proficient in Japanese, you have a compliance challenge: an employee who cannot understand the questionnaire cannot give accurate answers, which means the stress check serves no protective function for that person.
The law does not restrict stress checks to Japanese only. Providing the questionnaire in the employee's language is strongly recommended and is considered best practice.
Language options to look for in a provider:
| Language | Common industry contexts |
|---|---|
| English | IT, finance, research, multinational companies |
| Chinese (Simplified/Traditional) | Manufacturing, food service, retail |
| Vietnamese | Manufacturing, agriculture, care |
| Tagalog | Healthcare, service industry |
| Portuguese | Manufacturing (Brazilian communities) |
| Indonesian | Manufacturing, agriculture |
| Thai | Manufacturing, hospitality |
| Korean | IT, cosmetics, food manufacturing |
| Burmese | Manufacturing, agriculture |
When employees complete the questionnaire in their native language, the results are significantly more accurate and the protective function of the stress check is properly fulfilled.
Interview guidance for high-stress foreign employees should also be conducted with the assistance of an interpreter or a bilingual health professional.
7. Choosing an External Provider
Many companies — especially those without an in-house industrial physician — outsource the stress check to an external service provider. When evaluating providers, check for the following:
1. Licensed implementer on staff
Ask: "Who is the named implementer, and what is their license?" A provider without a named licensed implementer is a compliance risk.
2. Multilingual questionnaire support
If you have non-Japanese-speaking employees, confirm which languages are available and whether the translations are professionally validated (not machine-translated).
3. Group analysis report depth
Check whether the report includes: - Department-level breakdowns - Year-over-year trend comparison - Breakdown by job type or floor - Actionable recommendations
4. Interview guidance support
Can the provider arrange or conduct high-stress employee interviews? Some providers only handle the questionnaire phase and leave the interview logistics to you.
5. Integration with other HR tools
For maximum value, stress check results should connect to your broader HR ecosystem: 1-on-1 programs, pulse surveys, and retention risk management. Providers who offer these adjacent services in an integrated platform can significantly reduce administrative overhead.
8. Common Compliance Mistakes to Avoid
| Mistake | Why it's a problem |
|---|---|
| Running the stress check without a licensed implementer | Direct violation of Article 66-10 |
| Allowing HR staff to access individual results | Privacy violation; nullifies employee trust |
| Not getting Health & Safety Committee approval before starting | Procedural violation; will be flagged in an audit |
| Providing Japanese-only questionnaire to non-Japanese speakers | Results are inaccurate; employees cannot exercise their rights |
| Taking adverse action against an employee based on results or refusal | Illegal under Article 66-10(3); grounds for labor dispute |
| Failing to report to the Labor Standards Inspection Office | Reporting violation for applicable workplaces |
