f you are a foreign resident in Japan working under a work visa, quitting your job is a major immigration event.
Many people mistakenly believe that as long as their visa is still valid, they can remain in Japan without taking any action.
In reality, doing nothing after leaving your job can seriously affect your ability to stay in Japan in the future.

 

Failure to Notify Immigration

 

After leaving your company, you are legally required to notify the Immigration Services Agency within 14 days.
If you fail to submit this notification, immigration may consider that you did not properly follow the rules. This can negatively affect your next visa renewal and may result in a shorter period of stay or, in some cases, rejection.

 

Risk of Visa Revocation

 

Work visas are granted on the condition that you engage in approved employment activities.
If you stay in Japan for more than three months without working and without a legitimate reason, your status of residence may become subject to revocation procedures.
Job hunting, medical treatment, or other reasonable circumstances are usually considered valid reasons, but doing nothing or working without permission is risky.

 

Difficulty Renewing Your Visa

 

Even if your current visa has time remaining, problems often appear at the next renewal.
If you are unemployed at renewal time, immigration may determine that you no longer meet the requirements of a work visa.
If you support yourself mainly through part-time or simple labor jobs that do not match your visa status, renewal is also unlikely to be approved.

 

Tax, Pension, and Insurance Problems

 

After quitting your job, you must personally manage payments for resident tax, health insurance, and pension.
Late payments or unpaid amounts can have serious consequences, especially if you plan to apply for long-term residence or permanent residency in the future.
Even a short delay may negatively affect such applications.

 

What You Should Do After Quitting

 

To avoid immigration problems, it is essential to take action promptly.
Submitting the required notification, keeping records of your job search, and completing municipal procedures for insurance and tax payments all help demonstrate that you are responsibly living in Japan.

 

Final Thoughts

 

Quitting your job does not immediately cancel your visa, but doing nothing afterward can create serious immigration risks.
If you are unsure what steps to take, consulting an immigration professional early can help protect your future in Japan.

就労系の在留資格で日本に住んでいる外国人の方にとって、退職は入管上とても重要な出来事です。
「まだビザの期限が残っているから大丈夫」と考えて、何もしないままでいると、将来日本に住み続けることが難しくなる可能性があります。

 

入管への届出をしないリスク

 

会社を辞めた後は、14日以内に入管へ届出を行う義務があります。
これを行わないと、ルールを守らない人と判断され、次回の在留資格更新で不利になったり、在留期間が短くなる可能性があります。

 

在留資格取消しのリスク

 

就労ビザは、日本で働くことを前提に許可されています。正当な理由なく3か月以上働かずに滞在している場合、在留資格が取消しの対象となることがあります。
一方で、就職活動や病気療養など、合理的な理由がある場合は、直ちに問題になるわけではありません。

 

次回更新ができなくなる可能性

 

在留期間が残っていても、更新時に問題が生じます。
無職の場合は、在留資格の要件を満たさないと判断されやすく、アルバイト中心の生活も、就労ビザの趣旨に合わないとして不許可になる可能性があります。

 

税金・年金・保険の未納リスク

 

退職後は、住民税や健康保険、年金を自分で支払う必要があります。
未納や遅延があると、将来永住申請をする際に、ほぼ確実に大きなマイナス評価となります。

 

まとめ

 

会社を辞めても、すぐにビザが失効するわけではありません。しかし、何もしないことが最も危険です。
届出、就職活動の記録、役所での手続きをきちんと行うことが、日本での安定した生活を守ることにつながります。
