[1. Introduction: A Shift from “Reactive” to “Proactive” Immigration Enforcement]
As a Gyoseishoshi specializing in visa and status of residence applications, I provide daily consultations to companies and foreign residents in Japan.
On May 17, 2026, Yomiuri Shimbun Online reported a development of major importance to anyone involved in the employment of foreign nationals.
The Immigration Services Agency of Japan (ISA) has formally established a policy to strengthen enforcement against foreign nationals who illegally reside or work in Japan by deploying SNS-based intelligence gathering and analysis.
Until now, immigration enforcement has primarily been reactive — initiated by voluntary appearances of the individuals concerned or by information shared from the police. Going forward, however, the ISA will shift toward proactive enforcement, independently collecting and analyzing information circulating on social media platforms.
This article, written from the perspective of a Gyoseishoshi, explains the implications of this development and outlines the concrete measures that companies employing foreign nationals — as well as foreign residents themselves — should take as soon as possible.

[2. The ISA’s New Policy: SNS and AI-Based Intelligence Gathering]
■ Why SNS Analysis?
In recent years, social media platforms have become channels for the circulation of illegal information, including:
- Job advertisements that disregard the applicant’s status of residence
- “Underground” employment solicitations promising high income and promising work without identity verification
- Information related to the forgery of residence cards and passports
- Brokerage of sham marriages and fraudulent applications for status recognition
Such activities have historically been difficult for police and immigration officers to detect on a case-by-case basis.
■ Introduction of AI and Private-Sector Analytical Tools
The ISA plans to deploy artificial intelligence and private-sector analytical tools to systematically collect and analyze illegal online activity circulating on social media. Full operation is targeted for 2027 or later.
This is expected to reveal the digital footprints of brokers and employers who have previously evaded detection.
■ Enhanced Coordination with Local Governments
Local municipalities have reported an increase in resident inquiries concerning illegal employment cases. The ISA is also considering an expansion of regional consultation offices. In one prefecture with the highest number of illegal workers nationwide, a reward system for reporting malicious employers or brokers has already been introduced.
━━━━━━━━━━━━━━━━━━━━
[3. Current Situation in Numbers]
According to the ISA:
- Apprehensions in 2025: 1,837 (an increase of 459 from the previous year)
- Illegal overstayers as of January 1, 2026: 68,488 (a decrease of 6,375 from the same period last year)
While the total number of overstayers has declined, the number of apprehensions has risen — a clear sign that enforcement efforts are becoming more rigorous.
Crucially, many overstayers engage in illegal work to support themselves. Illegal overstay and illegal employment are closely interconnected issues, and behind every illegal worker stands an employer who either knowingly or negligently facilitates that employment.
━━━━━━━━━━━━━━━━━━━━
[4. The Crime of Facilitating Illegal Employment: Ignorance Is No Defense]
■ Relevant Legal Provisions
Article 73-2 of the Immigration Control and Refugee Recognition Act stipulates that the following acts constitute the crime of facilitating illegal employment:
- Causing a foreign national to engage in illegal work in the course of business activities
- Placing a foreign national under the employer’s control for the purpose of causing them to engage in illegal work
- Brokering, as a business, the engagement of foreign nationals in illegal work
Violations are punishable by imprisonment of up to three years, a fine of up to three million yen, or both.
■ Negligent Conduct Is Now Subject to Penalties
Following the June 2024 amendment to the Immigration Control Act, the crime of facilitating illegal employment now extends to negligent acts.
In practical terms, this means that even if an employer claims to have been unaware of the violation, they may still be subject to criminal penalties if negligence in verification is established. This is a critical legal change that employers must fully understand.
■ Practical Consequences for Businesses
The consequences extend far beyond criminal penalties:
- Suspension of eligibility to host Technical Intern Trainees or Specified Skilled Workers
- Exclusion from public procurement
- Loss of trust among business partners
- Reputational damage through media coverage
- Decline in morale and increased turnover among existing foreign staff
The indirect impact of these consequences can far exceed any monetary penalty.

[5. Four Compliance Measures Companies Must Implement Immediately]
■ Measure 1: Residence Card Verification and Authenticity Checks
At the point of hire, always verify the original residence card. Photocopies or smartphone images are not sufficient.
The ISA provides an official “Residence Card Reader Application” that allows IC chip data to be read for authenticity verification. Counterfeit residence cards have become increasingly sophisticated and are circulated on social media, making visual inspection alone insufficient.
■ Measure 2: Alignment Between Status of Residence and Job Duties
Each status of residence defines a specific scope of permitted activities. For example:
- “Engineer / Specialist in Humanities / International Services” does not permit unskilled labor.
- “Skilled Labor” permits only the specific fields recognized.
- “Student” permits part-time work only with permission for activities other than those permitted by the status of residence, capped at 28 hours per week.
- “Dependent” similarly requires such permission and is subject to the 28-hour rule.
Confirm that actual job duties clearly correspond to the holder’s status of residence.
■ Measure 3: Establishing a System to Manage Periods of Stay
Maintain centralized records of each employee’s period of stay and begin renewal procedures at least three months before expiration.
If renewal is overlooked and the period of stay expires, the foreign national becomes an illegal overstayer, and continued employment exposes the company to liability for facilitating illegal employment.
■ Measure 4: Compliance with the Foreign Worker Employment Notification Requirement
Under Article 28 of the Employment Measures Act, employers are required to submit a “Notification of Employment of Foreign Nationals” to Hello Work upon both hiring and separation.
Failure to comply is punishable by a fine of up to 300,000 yen. Although this is a fundamental requirement, it is frequently overlooked.
━━━━━━━━━━━━━━━━━━━━
[6. A Message to Foreign Residents: The Pitfalls of SNS Job Advertisements]
Foreign residents in Japan should also understand the following.
Job advertisements on social media offering “no status of residence required,” “no ID needed,” or “high daily pay” are almost always illegal.
Responding to such advertisements may result in:
- Revocation of status of residence due to unauthorized activity
- Deportation
- A five-year re-entry ban
- Severe negative impact on future permanent residence applications
For international students, exceeding the 28-hour weekly limit may seem like a minor matter, but it frequently results in denial of status renewal — with serious long-term immigration consequences.
━━━━━━━━━━━━━━━━━━━━
[7. The Greatest Risk Lies in Ignoring Gray Areas]
In my daily practice as a Gyoseishoshi, the most common consultation I receive begins with: “Is this really okay?”
In my experience, companies that leave gray areas unaddressed are those most likely to face serious problems later on.
Once the ISA’s AI- and SNS-based intelligence system becomes fully operational, issues that have long been overlooked may surface rapidly.
Rather than assuming “we are fine,” I strongly recommend a professional review of your internal compliance systems.
━━━━━━━━━━━━━━━━━━━━
[8. Conclusion: Preparing for an Era of Change]
- The ISA will strengthen enforcement against illegal employment using SNS and AI.
- Enforcement targets include both foreign nationals and the employers and brokers who facilitate illegal employment.
- The crime of facilitating illegal employment now extends to negligent conduct, punishable by up to three years of imprisonment or a fine of up to three million yen.
- Companies should immediately review four points: residence card verification, alignment of status and duties, period-of-stay management, and employment notification.
- Foreign residents should exercise particular caution regarding SNS-based job advertisements.
Foreign professionals are indispensable partners for the future of Japanese society. For that very reason, proper employment management is both a corporate responsibility and a foundation for protecting the stability of foreign residents’ lives in Japan.
