Workplace Mental Health Framework
Workplace mental health in Japan runs through a statutory screening system that checks employees for psychological burden once a year.12 If you work at a covered employer, the check, its privacy rules, and the follow-up path shape what support you can actually expect.
Procedures, fees, and requirements can change. Confirm current details at the Ministry of Health, Labour and Welfare stress-check pages. This article is general information, not medical or legal advice; for personal care decisions consult a licensed physician or qualified mental health professional, and for a contested harassment or leave case use a Labor Bureau consultation desk or an employment lawyer.
Overview
The framework has three layers: the annual ストレスチェック制度 (sutoresu chekku seido, "stress-check system") that screens employees, a voluntary follow-up interview with a physician for high-stress employees, and employer consultation measures for issues such as harassment.123 It covers employed residents at workplaces under the Industrial Safety and Health Act, which defines a worker broadly as a person employed at a business and paid wages.2
Coverage is not identical everywhere. The binding screening duty applies at workplaces with 50 or more workers, while smaller workplaces sat under an effort obligation until a scheduled 2028 change closes the gap.1 That size split explains much of the unevenness described below.
The Annual Stress Check
The stress check is employer-run screening required by the Industrial Safety and Health Act, in place since 2015.1 It looks for psychological burden early and routes high-stress employees toward a voluntary physician interview.2
Who must run it
Workplaces with 50 or more workers must run the check; workplaces below that line were expected to make efforts toward running it rather than bound by the same duty.12 The table below summarizes the line and its scheduled change.
| Workplace size | Duty before April 2028 | Duty from April 2028 |
|---|---|---|
| 50 or more workers | Mandatory screening1 | Mandatory screening1 |
| Fewer than 50 workers | Effort obligation12 | Mandatory screening under the May 2025 amendment (as of 2026-06; confirm current figures with the Ministry of Health, Labour and Welfare)1 |
The table above reflects the Ministry's June 2026 notice position (as of 2026-06). Confirm the current schedule with the Ministry before relying on the 2028 date for planning.
What the questionnaire covers
Employees answer a brief self-administered questionnaire about psychological burden and workplace stressors.2 The Ministry publishes a standard form and implementation manuals that employers use to run the survey.4
The questionnaire screens for burden levels; it does not diagnose anything. Treat it as a triage step that decides whether a follow-up conversation is worth your time.2
What happens after a high-stress result
A worker whose result meets the high-stress threshold may request a face-to-face interview with a physician.2 The interview happens only at the worker's request; a flag alone books nothing automatically. The flow looks like this:
The examining physician or nurse notifies the worker of the result directly.2 Results reach the employer only with the worker's consent, and the employer must not treat a worker disadvantageously for requesting the interview.2
After the interview, the employer must hear the physician's opinion and take appropriate measures for the worker's health.2 In practice that means adjustments such as changed duties, shorter hours, or a different placement, fitted to the worker's actual circumstances.2
Support Beyond the Check
The statutory check is a floor, not the whole support picture. Larger employers commonly add counseling channels on top of it, and those channels widened after 2020.
External EAP counseling
Many larger employers contract outside Employee Assistance Program providers whose counselors sit outside the company chain of command.4 Employees use these routes for confidential counseling separate from HR and their own manager, though exact offerings differ by contract. If language matters to you, confirm whether your employer's contract includes English-language counseling before you need it.
Remote-work era support at major employers
After 2020, remote and hybrid work spread at major employers, and associated support frameworks spread with it: online counseling access, manager check-in routines, and training on supervising distributed teams.4 These arrangements remain employer-specific rather than statutory. Treat them as a described trend in large-company practice, not a guaranteed entitlement.
Uneven Coverage at SMEs and Traditional Firms
Expectations set at a large employer do not transfer automatically to a small one. The statute itself created the two-tier picture, and workplace culture widens it further.
Why smaller workplaces differ
Below the 50-worker line, the binding duty did not apply until the scheduled 2028 change, so thinner provision at small and medium employers follows directly from the legal structure.1 Smaller workplaces are also less likely to retain a dedicated 産業医 (sangyo i, "occupational physician") or to run group-level analysis of results.12 Very traditional firms tend to stay closer to the legal minimum even where the duty applies, so assume less unless you see more.
Do not assume an annual questionnaire exists at a small or very traditional employer. Ask HR or your manager directly which screening, counseling, or consultation routes your workplace operates.1
What to do when your employer offers little
You are not limited to the employer channel. Public health-insurance-covered care routes and public consultation services remain available regardless of what your company runs.1 The harassment consultation routes in the next section are likewise open regardless of employer size.35
Harassment Overlap and Where to Report
Mental-health harm and workplace harassment often arrive together. The law treats them through separate duties that meet at the consultation desk.
How harassment connects to mental health
Workplace power harassment, or パワハラ (pawahara, "power harassment"), is defined by three cumulative criteria: conduct from a superior position, exceeding the necessary and reasonable scope of work duties, and harm to the working environment.6 The Ministry expressly lists a worker's physical and mental condition among the factors weighed when judging a case.6 Harassment in the Japanese Workplace: Pawahara, Sekuhara, Matahara covers the type-by-type detail; this section stays on the overlap and the reporting routes.
Consultation and reporting routes
Employers must run consultation systems and employment-management measures against power harassment.36 They must not dismiss or otherwise disadvantage a worker for seeking consultation or cooperating with one.3
When a workplace route stalls, disputes can go to the prefectural Labour Bureau director for advice, guidance, or recommendations, or to conciliation through the dispute-coordinating committee.3 The Ministry's foreign-workers portal publishes English overviews of power, sexual, and maternity-related harassment with countermeasure examples, which is a practical starting point before filing anything.5
Good to know
The stress check is screening, not a diagnosis
A low-stress result is not a clean bill of health, and a high-stress flag is not a diagnosis.2 Diagnosis and treatment decisions belong to a physician in a clinical setting, reached through the voluntary interview or an ordinary care route. Use the flag as a prompt to talk to someone qualified, not as a verdict.
Results are private, and the interview is voluntary
HR does not automatically see your answers, and a high-stress flag does not book you an interview on its own.2 Results go to you first and reach the employer only with your consent, and the interview requires your own request.2 Disadvantageous treatment for requesting it is prohibited.
Small-workplace employees should not assume a check exists
If you join a workplace with fewer than 50 workers, do not expect the same annual check a large employer runs.1 The binding duty below that line arrives with the April 1, 2028 change (as of 2026-06; confirm current figures with the Ministry of Health, Labour and Welfare); until then provision depends on each employer's voluntary effort.1 Ask what exists during onboarding rather than discovering the gap mid-crisis.
