As more companies in Japan hire foreign workers, many business owners wonder, “Do we really need to enroll foreign workers in social insurance?” While it is often assumed that treatment varies depending on the type of residence status—such as technical interns, specific skilled workers, or international students working part-time—the notion that “foreigners are exempt from enrollment” simply does not hold true.
Failure to enroll in social insurance not only results in retroactive premium claims but can also lead to administrative guidance and damage to the company’s reputation. Therefore, it is particularly important for companies that employ foreign workers to correctly understand the basic rules of social insurance.

Foreign Workers Are Generally Required to Enroll in Social Insurance
To put it simply, even foreign workers are required to enroll in social insurance if they meet the same eligibility criteria as Japanese nationals.
The term “social insurance” here primarily refers to the following:
・Health Insurance
・Employee Pension Insurance
In particular, employees regularly employed at corporate workplaces are, in principle, subject to enrollment in Health Insurance and Employee Pension Insurance, regardless of nationality.
For example, the following cases are highly likely to be subject to enrollment:
・Foreign nationals employed as regular employees
・Contract employees working 30 hours or more per week
・Part-time and casual workers who meet certain conditions
・Foreign nationals with Specific Skilled Worker status
・Trainees
On the other hand, short-term workers who do not meet the enrollment criteria may be excluded, just as Japanese nationals are.
Why Is Social Insurance Enrollment Required for Foreign Nationals?
The social insurance system is designed to “protect workers legally employed in Japan,” and there is generally no distinction based on nationality.
Enrollment in Health Insurance reduces the financial burden of medical expenses in the event of illness or injury, and enrollment in the Employees’ Pension Insurance leads to eligibility for pension benefits in the future.
Furthermore, even if a foreign worker returns to their home country, there is a system in place that allows them to claim a “lump-sum withdrawal payment” if certain conditions are met. This system allows for the reimbursement of a portion of the Employees’ Pension Insurance and National Pension premiums paid in Japan.
From a compliance perspective, ensuring proper enrollment in social insurance is also extremely important for employers. In recent years, in particular, oversight regarding the employment of foreign nationals has been strengthened, and failure to enroll in social insurance can affect visa status renewals or result in regulatory guidance.
Common Misconceptions
The following misconceptions are frequently encountered regarding the employment of foreign nationals.
“National Health Insurance is sufficient for foreign nationals.”
This is incorrect. If the employee meets the eligibility criteria for company-sponsored social insurance, they must enroll in the company’s health insurance plan rather than National Health Insurance.
“Trainees receive special treatment, so they do not need to enroll.”
Since trainees are treated as workers, they are generally subject to social insurance enrollment.
“If the individual says they don’t want to enroll, we don’t have to enroll them.”
This is also a misconception. If the enrollment requirements are met, there is an obligation to enroll regardless of the individual’s wishes. Even with mutual agreement between employer and employee, non-enrollment is not permitted.
Even Japanese nationals must enroll if they meet the requirements, regardless of their personal wishes.
“Since it’s short-term employment, we don’t need to enroll them.”
Even for short-term employment, an obligation to enroll may arise if the requirements are met. It is risky to judge solely based on the contract period.
Practical Considerations
When handling social insurance procedures for foreign workers, verifying their status of residence and period of stay is extremely important.
For example, discrepancies between the information on the Residence Card and the employment contract can hinder procedures for employment insurance and social insurance. Additionally, since names are written in the Roman alphabet, this is a common source of input errors on insurance cards and pension records.
Furthermore, there are many cases where foreign workers themselves do not fully understand the system, which can lead to disputes such as “I don’t understand why insurance premiums are being deducted from my salary.” Therefore, it is advisable to provide careful explanations using materials in their native language and with the assistance of an interpreter.
In addition, failure to enroll in social insurance may result in an investigation by the Labor Standards Inspection Office or the Pension Office. Under the Specified Skilled Worker Program, the host company’s proper compliance with social insurance enrollment requirements is highly emphasized, making a thorough understanding of the system essential.
Support Provided by Professional Practitioners
Social insurance and foreign employment procedures involve complex systems, and it is often difficult for companies to handle them accurately on their own.
Certified Social Insurance and Labor Consultants can assist with enrollment procedures for health insurance, employee pension insurance, employment insurance, and workers’ compensation insurance, as well as provide labor management support. Additionally, Certified Administrative Scriveners can handle support for residence status applications and documents related to the employment of foreign nationals.
In particular, since “residence status” and “labor management” are closely linked in the employment of foreign nationals, there is an increasing trend for Social Insurance and Labor Consultants and Administrative Scriveners to collaborate in providing support.
To prevent the risks associated with non-enrollment, it is important to consult with experts at an early stage to confirm that your company’s employment practices are in compliance with the law.
Summary
Even for foreign workers, as long as they are working in Japan, there is an obligation to enroll in social insurance if certain conditions are met. Nationality does not exempt them from this obligation; they are subject to the same rules as Japanese nationals.
In particular, for companies that accept Technical Intern Trainees or Specific Skilled Foreign Workers, social insurance enrollment status is a critical compliance issue.
Rather than thinking, “They’re foreigners, so they deserve special treatment,” implementing proper employment management and social insurance procedures will help mitigate corporate risks. If you have any concerns, we recommend consulting with experts such as social insurance and labor consultants or administrative scriveners to ensure accurate compliance.
