Secondment, Transfers, and M&A for Foreign Staff in Japan: Work Visa Compliance Guide for Corporate HR

This article is written by a Japanese local.

“Our company is executing an inter-company secondment within our group. Must our foreign employee change their visa?”

“Due to a business transfer or corporate split, foreign engineers are transferring to a new entity. What procedures are required under the Immigration Control Act of Japan?”

In Japanese corporate management, secondments (出向 – Shukko) and transfers (転籍 – Tenseki) are routine operational tools to foster talent and realign business units. However, when the impacted personnel hold work visas—specifically the “Engineer/Specialist in Humanities/International Services” (技人国 – Gijinkoku) status—treating them identically to local Japanese employees carries substantial legal liability.

Under Article 73-2 of Japan’s Immigration Control Act, placing a foreign professional in unauthorized work creates direct corporate exposure to Illegal Employment Facilitation (penalties up to 3 years imprisonment or corporate fines up to 3 million yen).

The two critical vulnerabilities in corporate restructuring are the alteration of the contracted legal entity and the alignment between the employee’s academic background and their specific daily duties at the host entity. Failure to handle these transitions properly frequently results in visa renewal denials, plunging key personnel into departure procedures and disrupting business operations.

This guide outlines the legal distinctions between secondment and transfer, mandatory 14-day immigration notifications, and actionable protocols to ensure corporate compliance.

1. Legal Classification: Secondment (在籍出向) vs. Transfer (転籍)

Restructuring Type	Employment Contract Status	Change of Visa Category Required?	Immigration Status & Key Obligation
Secondment (在籍出向 – Shukko)	Employment relationship with the home company is retained while establishing secondary contractual governance with the host company.	Generally No. (Assuming duties at the host entity strictly remain within statutory visa boundaries).	Mandatory 14-day “Notification of Contracting Organization.” Compensation may be disbursed by either entity, but statutory salary parity with Japanese peers must be maintained.
Transfer (転籍 – Tenseki via M&A/Spin-off)	Contract with the original entity is formally severed; an entirely new employment contract is executed with the successor entity.	Generally No. (Provided job functions remain within the authorized scope of activities).	Legally equivalent to changing employers. In addition to the mandatory 14-day filing, obtaining a Certificate of Authorized Employment (就労資格証明書) is strongly advised to prevent future renewal failure.

In neither scenario is an immediate change in the broad visa classification required, provided duties remain professional and technical. However, this does not mean HR can proceed without official immigration filings.

2. The Three Essential Compliance Protocols for Corporate HR

Protocol 1: Verification of Academic-Job Relevancy at the Host Entity

While domestic Japanese staff can be rotated to logistics hubs, construction sites, or retail counters for operational support, assigning foreign work visa holders to non-specialized operational roles constitutes unauthorized work (資格外活動) and illegal labor under Japanese law.

• Verify that technical staff will engage exclusively in specialized tasks directly related to their university major or verified 10-year professional experience.
• Ensure the host entity has sufficient volume of professional work so the employee is not relegated to manual or routine clerical tasks.

Protocol 2: Mandatory 14-Day “Notification of Contracting Organization”

Under Article 19-16, Item 1 of the Immigration Act, foreign professionals must formally notify the Immigration Services Agency within 14 calendar days of entering into a new contract, changing employer names, or transferring entities.

• Obligated Party: Legally, the foreign employee bears the obligation, but corporate HR must supervise and facilitate the filing via the Immigration Electronic Notification System.
• Non-Compliance Penalty: Failure to report triggers individual administrative fines up to 200,000 yen and leads to automatic demotion to a 1-year visa or outright denial at the next renewal.

Protocol 3: Absolute Defense via the Certificate of Authorized Employment

The primary threat confronting HR is the time bomb: 1 to 3 years after secondment, when the employee applies for a standard visa renewal, Immigration rules that the host company’s work does not qualify, denying the extension.

To eliminate this systemic risk in advance, employers should secure a Certificate of Authorized Employment (就労資格証明書 – Shuro Shikaku Shomeisho) under Article 19-2.

【Strategic Value of the Certificate of Authorized Employment】

• Immigration formally evaluates the new company and role in advance, issuing an official certificate confirming that the foreign national is authorized to perform those duties.
• Once issued, subsequent visa renewals are practically guaranteed to be approved quickly, as substantive eligibility has already been validated.
• When transferring multiple engineers simultaneously to newly incorporated subsidiaries or spin-offs, this certificate fulfills corporate legal due diligence.

3. Key Pitfalls in M&A, Corporate Splits, and Business Transfers

When executing corporate divestitures, asset purchases, or mergers, HR and legal teams must address two structural immigration variables:

• Corporate Category Demotion: If employees transfer from a Tier 1 or Tier 2 listed company to an unlisted spin-off or newly established operating company (Tier 3 or 4), documentary burdens skyrocket. Business plans, client pipeline contracts, and financial forecasts must be compiled to substantiate corporate continuity.
• Remuneration Equivalence Standards: Modifying compensation structures during post-merger integration requires strict proof that foreign professionals continue to receive pay equal to or higher than Japanese nationals in comparable positions.

4. Summary: Align Legal Compliance Before Issuing Personnel Orders

Reorganizing foreign human resources is not merely an internal HR restructuring; it is an administrative alteration of legal presence governed by statutory immigration mandates.

Assuming that internal corporate orders supersede immigration scrutiny exposes foreign talent to deportation risks and subjects the corporation to criminal liability under illegal employment facilitation provisions.

Executing exhaustive job-qualification screening and proactively securing Certificates of Authorized Employment prior to organizational transfers represents the definitive legal standard for responsible multinational employers operating in Japan.
