On August 8, 2026, in Hamana Ward, Hamamatsu City, Shizuoka Prefecture, three women—two Chinese nationals and one Vietnamese national—were arrested on suspicion of violating the Adult Entertainment Business Law (Fūeihō). They allegedly operated a men’s spa offering sexual services in an area where storefront-type adult entertainment establishments are prohibited. The case came to light after local residents reported that “an unspecified number of people were coming and going” from the premises.

This incident offers crucial lessons for foreign residents in Japan and companies employing them. This article, written from the perspective of a visa and residence status specialist, examines the legal risks highlighted by this case and outlines the necessary steps companies should take.

Overview and Background of the Case

According to reports, a 48-year-old Chinese national operated the establishment, while a 44-year-old Chinese national and a 31-year-old Vietnamese national worked as employees, allegedly providing sexual services. The incidents occurred on May 11 and 12, 2026, and the investigation began after the property management company contacted the police in April following complaints from residents.

What makes this case particularly significant is not just the violation of the Adult Entertainment Business Law, but the involvement of foreign residents. Foreign nationals working in Japan are subject to strict restrictions under the Immigration Control and Refugee Recognition Act (Immigration Act), and working in unauthorized industries constitutes a serious legal violation.

Basics of Residence Status and Work Restrictions

Every foreign national residing in Japan must hold a specific residence status. There are various types, including “Engineer/Specialist in Humanities/International Services,” “Skilled Labor,” “Specified Skilled Worker,” “Permanent Resident,” and “Spouse or Child of Japanese National.”

Crucially, each residence status clearly defines the types of work activities permitted. For instance, the “Engineer/Specialist in Humanities/International Services” status allows office work, translation, or engineering roles, but does not permit unskilled labor or work in the adult entertainment industry.

Impact of Adult Entertainment Law Violations on Residence Status

When foreign residents are involved in violations of the Adult Entertainment Business Law, they face the following serious consequences:

1. Revocation of Residence Status

Under Article 22-4 of the Immigration Act, residence status may be revoked if false applications are submitted or unauthorized activities are conducted. Involvement in criminal cases such as violations of the Adult Entertainment Business Law significantly increases the risk of revocation.

2. Denial of Residence Period Renewal

When applying to renew a residence status, applicants must demonstrate good conduct. A criminal record involving violations of the Adult Entertainment Business Law greatly increases the likelihood of renewal denial.

3. Potential Deportation

Under Article 24 of the Immigration Act, foreign nationals who commit certain crimes are subject to deportation. Those convicted of Adult Entertainment Business Law violations may face deportation orders.

4. Future Entry Restrictions

Once deported, individuals are generally prohibited from entering Japan for five years. In serious cases, the entry ban may extend to ten years.

Employer Risks: The Crime of Facilitating Illegal Employment

Often overlooked, companies employing foreign nationals also face significant legal risks. Article 73-2 of the Immigration Act establishes the “Crime of Facilitating Illegal Employment,” which penalizes the following acts:

  1. Employing a foreign national in illegal work activities
  2. Arranging illegal work activities for a foreign national
  3. As a business, assisting those who employ foreign nationals in illegal work activities or arrange such activities

Violations carry penalties of up to three years’ imprisonment or fines up to 3 million yen. Claiming ignorance is not a valid defense.

Steps Companies Should Take

Companies employing foreign residents must implement the following measures:

1. Strict Verification at Hiring

  • Verify the original residence card (copies alone are insufficient)
  • Confirm the type of residence status and work restrictions
  • Check the residence period expiration date
  • Verify authenticity using the Immigration Services Agency’s “Residence Card Number Verification System”

2. Ensure Alignment Between Job Duties and Residence Status

Even after hiring, companies must continuously verify that the actual work assigned matches the activities permitted under the employee’s residence status.

3. Regular Compliance Checks

  • Periodically confirm that residence periods have not expired
  • Track residence status renewal status
  • Re-verify residence status compatibility when job duties change

4. Implement Internal Training

It is essential to share basic knowledge about employing foreign nationals not only with HR personnel but also with frontline managers.

5. Establish Access to Expert Consultation

Build a system that allows immediate consultation with specialists when questions or uncertainties arise.

What Foreign Residents Should Keep in Mind

Foreign residents themselves must also pay attention to the following:

1. Understand Your Residence Status and Work Restrictions

It is crucial to accurately understand what types of work you are permitted to perform.

2. Avoid Suspicious Job Offers

Be cautious of job listings that promise high pay or lack clear descriptions of job duties.

3. Review Employment Contract Details

Confirm that the work described in the contract is permitted under your residence status.

4. Consult Experts When in Doubt

If you have any concerns, we recommend consulting specialists such as immigration lawyers or administrative scriveners.

Conclusion

The recent Adult Entertainment Business Law violation case in Hamamatsu City serves as a stark reminder of the importance of proper residence status management. For foreign residents, risking future residence status for temporary income is never a wise decision. For companies, failure to maintain proper oversight can result in criminal liability.

With proper knowledge and management systems, these risks are entirely avoidable. If you have any concerns about residence status or foreign employment matters, please consult a specialist. Early intervention is the best way to prevent future problems.

In today’s globalized world, employing foreign nationals is a key element of business growth. However, this is only sustainable with proper legal management. We hope this article serves as a resource for foreign residents and their employers to understand legal risks and take appropriate action.
