Special Subsidiary System for Disability Employment — Japan

In Japan, the Special Subsidiary System (特例子会社制度 / Tokurei Kogaisha Seido) is a mechanism under the Act on Promotion of Employment of Persons with Disabilities (障害者雇用促進法) that allows a parent company to establish a subsidiary specially designed to employ and support persons with disabilities. If the subsidiary satisfies statutory requirements and receives recognition from the Minister of Health, Labour and Welfare, employees with disabilities working there can, for purposes of the statutory employment-rate calculation, be treated as employees of the parent company.

1. Meaning and Purpose

The system was created to promote stable and effective employment of persons with disabilities by allowing companies to concentrate appropriate employment arrangements, workplace support, job design and supervision within a subsidiary.

The important point is that the subsidiary remains a separate legal company, but employment-rate legislation creates a statutory fiction under which its workers and workplace are treated as belonging to the parent company for specified purposes. Article 44 of the Act provides the statutory basis.

The original administrative explanation of the system specifically recognized that a parent company could establish a separate company or facility where workers with disabilities could be employed under specially adapted conditions.

2. Legal Framework

The principal legislation is the Act on Promotion of Employment of Persons with Disabilities.

Article 43 — Employment obligation

Covered employers are subject to the statutory employment-rate system for persons with disabilities. Employers must also report their employment situation as required by law.

Article 44 — Special subsidiary

Article 44 provides that where a qualifying subsidiary has obtained the required recognition from the Minister, workers employed by that subsidiary may be treated as workers employed exclusively by the parent company, and the subsidiary's establishment may be treated as the parent company's establishment for the relevant provisions.

Therefore, the system is not simply an ordinary outsourcing arrangement. It is a statutory mechanism for calculating disability employment within the corporate group.

3. Main Characteristics

A. Separate corporate entity

A special subsidiary normally has its own corporate personality, management and employment relationships.

However, for disability-employment-rate purposes, its employees may be counted together with the parent company's employees.

B. Special consideration for disabled employees

The subsidiary is expected to provide an employment environment particularly suited to persons with disabilities.

Examples can include:

• adapted work processes;
• specially designed jobs;
• workplace support personnel;
• individualized training;
• modified working arrangements;
• appropriate supervision;
• accessible facilities;
• consultation and occupational support.

The Ministry of Health, Labour and Welfare provides examples of reasonable accommodation actually used by employers, including special subsidiary workplaces.

C. Recognition is required

A company cannot simply declare itself a "special subsidiary." The statutory requirements must be satisfied and the relevant recognition obtained.

D. Employment-rate calculation

The principal benefit for the corporate group is that qualifying employees of the special subsidiary can be included when calculating the parent's statutory disability employment rate.

4. Requirements and Compliance

The exact statutory requirements should be checked against the current implementing regulations and the recognition process, but the system generally requires a substantial relationship between the parent and subsidiary and arrangements demonstrating that the subsidiary is genuinely designed to promote stable disability employment.

Important compliance areas include:

1. Corporate relationship with the parent company
2. Appropriate employment of persons with disabilities
3. Special employment-management arrangements
4. Ability to promote and stabilize disability employment
5. Appropriate workplace facilities and support
6. Application and recognition by the competent authority
7. Continuing compliance after recognition

The Ministry currently provides application forms and explanatory materials for the special subsidiary system and related corporate-group calculation systems.

5. Reasonable Accommodation in a Special Subsidiary

The special subsidiary system does not mean that all employees with disabilities can automatically be treated identically.

An employer must consider the individual's disability and the actual difficulties experienced at work.

For example, a special subsidiary may use:

• simpler or more clearly structured work instructions;
• additional training;
• support staff;
• flexible scheduling;
• rest arrangements;
• modification of the physical workplace;
• assistance with communication;
• gradual introduction of responsibilities.

A JEED case involving a person with a mental disability illustrates measures such as allowing a support-agency employee to attend the interview and adapting employment arrangements to the individual's circumstances.

6. Relationship with Discrimination Law

The special subsidiary system should not be confused with a legal exemption from disability-discrimination rules.

Japan's disability-employment legislation separately addresses:

• prohibition of discriminatory treatment; and
• the employer's obligation concerning reasonable accommodation.

Therefore, establishing a special subsidiary does not by itself remove the employer's obligations concerning fair treatment and reasonable accommodation.

7. Important Legal Issues

Issue 1 — Genuine employment versus quota compliance

A special subsidiary should not function merely as a numerical device for satisfying the statutory employment rate.

The employment should represent genuine and stable employment of persons with disabilities.

A 2026 academic study examining Japanese special subsidiaries reported concerns that some corporate groups establish such subsidiaries primarily to meet the statutory quota and that separation from ordinary workplaces can create hierarchical relationships. These are academic findings about employment practices, rather than a statement that every special subsidiary operates in this manner.

Issue 2 — Reasonable accommodation

Even in a specially structured workplace, employers need to consider the employee's individual circumstances.

Issue 3 — Work allocation

Job allocation must be consistent with the employee's abilities and the employment contract. Merely assigning an employee with a disability to low-value work without considering development or meaningful employment can create legal and practical problems.

Issue 4 — Health and safety

Special subsidiary employees remain workers protected by labour and occupational-safety legislation. Disability employment status does not remove occupational accident or workers' compensation protections.

8. Case Laws / Judicial Decisions

Important note: Reported Japanese decisions specifically deciding the validity of the Special Subsidiary System itself are relatively limited. Consequently, the following cases include the leading disability-employment and reasonable-accommodation decisions that are relevant to the operation and legal obligations of special subsidiaries.

Case 1 — NEC Corporation Case

Tokyo District Court, 29 July 2015

This is an important Japanese disability-employment case concerning reasonable accommodation.

The case concerned an employee who developed a disability and the employer's response to the employee's changed working circumstances. The decision is widely discussed in Japanese employment-law literature concerning reasonable accommodation for disabled workers.

Significance:
The case demonstrates that disability employment cannot be examined solely through the question of whether the employer has formally employed a person with a disability. The employer's response to the employee's actual employment difficulties is also legally important.

Relevance to special subsidiaries:
A special subsidiary that has specifically been established to employ persons with disabilities may be expected to pay particular attention to appropriate workplace arrangements.

Case 2 — Intellectual Disability / Special Subsidiary Workers' Mental-Disorder Case

Tokyo District Court, Reiwa 2 (Gyo-u) No. 386

This is particularly important because the worker was actually employed by a special subsidiary under Article 44.

The employee had an intellectual disability and had been employed through the disability-employment framework of the special subsidiary. Initially, the employee performed cleaning work. As physical capacity declined with age, the company considered moving the worker to less physically demanding work, eventually assigning work including business-card production and cleaning.

The litigation concerned whether the employee's subsequent mental disorder was sufficiently connected to work for workers' compensation purposes.

Significance:
The case demonstrates that special-subsidiary status does not eliminate ordinary occupational-health and workers' compensation issues.

Key lesson:
Specialized disability employment requires continuing assessment of workload, work allocation, health and individual circumstances.

Case 3 — Disability-Related Dismissal / Reasonable Accommodation Litigation

Japanese disability-employment case law includes cases concerning employees whose physical or mental condition changes during employment and whether the employer sufficiently considered alternative working arrangements before termination.

Academic reviews of Japanese disability-employment litigation identify cases involving:

• workers who acquired physical disabilities during employment;
• dismissal following mental-health difficulties;
• failure to provide appropriate accommodation;
• employees who could no longer perform ordinary work because of illness or disability. 

Significance:
For special subsidiaries, the existence of specialized employment arrangements makes the examination of alternative duties, workplace adjustments and continued employment particularly important.

Case 4 — Intellectual Disability and Employer Abuse / Wage Dispute

Japanese disability-employment case-law literature identifies litigation involving an employee with an intellectual disability where issues included employer abuse, unpaid wages and misuse of disability-related benefits.

Significance:
A special subsidiary does not receive a legal exemption from basic employment protections. Employees with disabilities remain entitled to wages and protection from unlawful treatment.

Practical implication:
Special subsidiary management must maintain proper payroll, employment records, supervision and grievance procedures.

Case 5 — Death of a Worker with Intellectual Disability / Employer's Duty of Care

Japanese disability-employment case-law literature also identifies litigation concerning the death of a worker with a mild intellectual disability and the question of whether the employer had taken sufficient precautions.

Significance:
Employers must consider the particular characteristics and risks affecting individual disabled employees when designing work and safety procedures.

Relevance to special subsidiaries:
Because special subsidiaries are specifically structured around disability employment, workplace safety systems, instruction and supervision can become particularly important evidence in litigation.

Case 6 — Employee with Mental Health Problems and Dismissal

Another category of Japanese disability-employment litigation concerns a worker who developed depression in connection with psychological burdens at work and was subsequently dismissed. Japanese legal scholarship identifies this as one of the cases relevant to reasonable accommodation under disability-employment legislation.

Significance:
The legal analysis focuses not simply on the employee's diagnosis but on the employer's response to the employee's work-related limitations and the feasibility of adjustments.

Relevance to special subsidiaries:
Special subsidiaries frequently have specialized support structures, making questions of consultation, work adjustment and individualized management especially relevant.

9. Practical Compliance Checklist

A company operating a special subsidiary should maintain:

10. Advantages of the System

The Special Subsidiary System can allow a corporate group to:

• concentrate disability-employment expertise;
• create specially adapted workplaces;
• develop specialized support personnel;
• design suitable jobs;
• improve employment stability;
• centralize disability-related training;
• coordinate employment across the corporate group;
• count qualifying subsidiary employees toward the parent's statutory employment rate. 

JEED examples demonstrate different forms of work performed in special subsidiaries, including cleaning, postal distribution, printing, packaging, administrative services and other outsourced corporate functions.

11. Limitations and Legal Risks

The system can also create legal and policy issues.

A. Segregation

If disabled employees are permanently separated from the ordinary workforce, questions may arise concerning inclusion and career development.

B. Token employment

Employers should avoid creating positions merely to increase the numerical employment rate.

C. Limited career progression

Special subsidiaries should consider whether employees have meaningful opportunities for training, skill development and advancement.

D. Excessive paternalism

Support should facilitate employment rather than unnecessarily restricting the employee's autonomy.

E. Continuing accommodation

Accommodation should be reviewed when the employee's circumstances change.

12. Conclusion

Japan's Special Subsidiary System (特例子会社制度) is a statutory mechanism designed to make disability employment easier to organize within corporate groups. Under Article 44 of the Act on Promotion of Employment of Persons with Disabilities, qualifying subsidiary employees can, after the required recognition, be treated as employees of the parent company for the relevant employment-rate provisions.

The system therefore combines corporate-group employment planning with disability-specific employment support. However, recognition as a special subsidiary does not remove ordinary obligations concerning wages, safety, reasonable accommodation, non-discrimination and lawful employment practices.

The most directly relevant recent litigation is especially significant because it involved a worker actually employed by a special subsidiary and examined the relationship between disability, work allocation, mental disorder and workers' compensation.

For legal compliance, the central principle is that a special subsidiary should function not merely as a method of satisfying the statutory employment quota, but as a genuine employment structure capable of providing stable, safe and appropriately accommodated employment for persons with disabilities.
