Japan Work Visa Job Change Manual: Utilizing the Certificate of Authorized Employment and Avoiding Illegal Labor Risks

This article is written by a Japanese local.

“I want to quit my current company and change jobs, but what are the necessary visa procedures?” “Since my residence card is still valid for another two years, is it okay if I don’t take any action after changing jobs?”

If you hold a “Engineer/Specialist in Humanities/International Services” visa and are thinking this way, you are in extreme danger. If you proceed with a job change without accurately understanding the rules of the Immigration Services Agency, you may fall into a fatal trap that forces you to leave Japan (forced return) in the worst-case scenario.

This article thoroughly explains the objective actions you must take before and after changing jobs, and details how to utilize the “Certificate of Authorized Employment” (Shuro Shikaku Shomeisho)—the ultimate defense to protect your career—to ensure you do not fall into unintentional “illegal employment.”

1. The Ironclad Rule [Before Changing Jobs]: Utilize the Certificate of Authorized Employment

As a major premise, the work visa you currently hold was specially granted after screening the “job duties and financial stability of your previous company.” If you change jobs and move to a different organization, your job duties and the new company’s financial situation will naturally change. Just because you were approved at your previous company does not guarantee unconditional approval at the next one.

Therefore, when you receive a job offer, before submitting your resignation to your current company, you must confirm: “Does this new job truly meet the legal standards of my current work visa?” The most objective and reliable method to prove this is to apply to Immigration for the issuance of a “Certificate of Authorized Employment.”

By using this system, you can obtain official prior assurance from Immigration that “my new job duties are legal and fall within the scope of my current visa” before actually changing jobs.

Even in the unlikely event that Immigration determines the new job duties do not match your visa, as long as you haven’t quit your current job yet, you have the option to decline the job offer and stay at your current company. In this way, there is an immense advantage in completely avoiding the worst-case risk of becoming unemployed due to visa issues.

2. The “Illegal Employment” Time Bomb: Leaving Things Unchecked [After Changing Jobs]

What happens if you jump the gun and change jobs without confirming the match via the Certificate of Authorized Employment? If you ignore the procedure thinking, “My visa still has time left, so I’m fine,” you will be waiting for three terrifying traps.

Trap 1: The Fatal Misunderstanding that “Remaining Visa Period = Legal”

Even if your residence card has time left, it is strictly on the condition that you continue to engage in the highly skilled activities appropriate for your visa category. If your duties at the new company do not meet the visa requirements (e.g., simple labor), you are engaging in “activities outside the scope of permitted activities,” which is prohibited by the Immigration Act. From that moment, you fall into a state of de facto illegal employment.

Trap 2: A Good Track Record Turns into “Proof of Illegal Labor”

Suppose you changed jobs without confirming the match, and apply for a visa renewal one or two years later. At this time, Immigration will strictly screen the job duties and financial status of your new company for the first time. If they determine that the new job does not meet the requirements, the track record of you working diligently at the new company for years will instantly turn into “undeniable proof of long-term illegal employment.” As a result, your renewal will be denied immediately, and your career in Japan will be forcibly terminated.

Trap 3: The Risk of the Company Being Ruined by the “Crime of Promoting Illegal Employment”

The foreign national is not the only one who takes damage. The company that casually hired you, assuming “there should be no problem since their residence card has time left,” will bear the risk of being charged with a serious crime: “Promoting Illegal Employment (up to 3 years in prison or a fine of up to 3 million yen).” The excuse “we didn’t know the immigration rules” will not be accepted under any circumstances.

3. It’s Not Too Late Even if You’ve Already Changed Jobs! Get the Certificate Now

Even if you have already completed your job change and have started working at the new company, it is never too late to take action. Before the “time bomb” of your next visa renewal explodes, please apply for the Certificate of Authorized Employment right now.

If you obtain this certificate before the renewal period, you will have essentially cleared Immigration’s substantive screening in advance. Your visa renewal a few years later will be treated as a “simple period extension at an already-screened, legal company,” allowing you to reduce the risk of a denial-forced return to nearly zero.

4. The Absolute Duty When Changing Jobs: “Notification of the Accepting Organization” (Within 14 Days)

Separate from the Certificate of Authorized Employment, an absolute legal requirement that every foreign national who changes jobs must never forget is the “Notification concerning the accepting organization.”

When you resign from your previous company and when you join a new company, the law requires you to submit a designated notification to Immigration within 14 days of each event occurring. If you neglect this notification, you may receive a severe negative evaluation during your next visa renewal or future Permanent Residency application for “lacking awareness of legal compliance,” and you may also be subject to a fine of up to 200,000 yen.

5. Common Job Change Troubles and Q&A

Here, we organize common practical questions regarding job changes.

Q. Is it possible to change jobs to a completely different industry?	A. Yes, conditionally. It is fine if the industry of your new company is different, but the absolute condition is that there is a logical match between “your major at university/vocational school (completed subjects)” and “your job duties at the new company.” Changing to a job with no relevance to your degree will be denied.
Q. After resigning, can I remain unemployed until I find a new job?	A. The grace period is generally “3 months.” If you fail to engage in the activities permitted under your original visa for 3 months or more without a justifiable reason (such as having evidence of actively seeking employment through Hello Work), your status of residence is subject to revocation. Careful schedule management is required so as not to prolong the blank period.

6. Conclusion: A Lawful Job Change Based on Objective Rules

The rules of Japanese immigration practices are administered extremely strictly. Your precious career, and the social credibility of the company that hired you, must not be lost due to assumptions or lack of knowledge.

Do not ignore the risks before and after a job change. Fulfill your duty of the “Notification concerning the accepting organization” within the deadline, and utilize the “Certificate of Authorized Employment” to objectively back up the legality of your duties. Complying with these procedures is the only approach to continuing a long, stable, and successful career in Japan.
