Changing Visa Status in Japan: Timing Explained
When is the right time to change your visa status in Japan? This guide explains application timing, deadlines, and common mistakes for foreign residents living in Japan.

When Can You Change Your Visa Status in Japan? A Complete Guide for Foreign Residents

For foreign residents living in Japan, understanding when you can change your visa status is extremely important.
Applying too late—or starting a new activity too early—can cause serious immigration problems.
In Japan, a change of status of residence is allowed only under specific conditions and timing. This article explains those rules in clear and simple English.

 

The Basic Timing for Applying

 

You can apply to change your visa status after your new activity has been clearly decided, and before your current period of stay expires.
For example, if you are changing jobs, you may apply after you receive a formal job offer and sign an employment contract.
If you are getting married, you can apply after your marriage is legally registered.
If you are a student graduating and starting work, you can apply once your graduation is confirmed and you receive a job offer.
For students graduating in March, immigration usually allows applications to start around December, but only if graduation and employment are reasonably certain.

 

Do Not Start the New Activity Before Permission

 

One of the most important rules is that you must not start the new activity before permission is granted.
If you begin working, managing a business, or engaging in a new activity that requires a different visa before approval, it may be considered unauthorized activity. Even if your employer agrees, immigration law does not allow it.

 

Application Deadline and Review Period

 

Your application must be accepted by immigration before your current visa expires.
If your application is accepted in time, you are usually allowed to stay in Japan while the review is ongoing.
The review process often takes one to two months, and sometimes longer depending on your situation. During this period, you must continue activities permitted under your current visa only.

 

Difference Between Extension and Change

 

It is important to understand the difference between visa extension and visa change.
A visa extension is used when you continue the same activity and simply need more time.
A change of status is required when your main activity itself changes, such as switching from student to worker, or from employee to spouse.
The timing rules are different, so choosing the wrong procedure can cause delays or rejection.

 

Important Note About Tourist Visas

 

In principle, you cannot change your visa status from a temporary visitor (tourist) visa while staying in Japan.
Except in very rare cases, you must return to your home country and apply through a Certificate of Eligibility.

 

Final Advice

 

Changing your visa status in Japan is not difficult if you apply at the right time and follow the rules carefully.
However, timing mistakes are a common reason for rejection.

 

If you are unsure, seeking professional advice before applying can help protect your future life in Japan.

日本に住む外国人にとって、在留資格を変更できるタイミングを理解することは非常に重要です。申請が遅れたり、許可前に新しい活動を始めてしまうと、深刻な問題につながります。
日本では、在留資格の変更は決められた条件とタイミングでしか認められていません。

 

申請できる基本的なタイミング

 

在留資格の変更は、新しい活動内容が明確に決まった後で、現在の在留期限が切れる前に申請できます。
転職の場合は、内定を受け、雇用契約が成立した後。
結婚の場合は、婚姻届が受理された後。
留学生の場合は、卒業見込みが立ち、就職先が決まった後です。
3月卒業予定の留学生については、卒業と就職がほぼ確実であれば、12月頃から申請できるのが一般的です。

 

許可が出る前に新しい活動を始めない

 

最も重要なルールは、許可が出る前に新しい活動を始めてはいけないという点です。
許可前に就労や事業活動を始めると、不法就労(資格外活動)と判断される可能性があります。

 

申請期限と審査期間

 

申請は、現在の在留期限までに入管で受理される必要があります。受理されていれば、審査中も引き続き日本に滞在できます。
審査期間は通常1〜2か月程度ですが、内容によってはそれ以上かかることもあります。
審査中は、現在の在留資格で認められた活動のみ行えます。

 

「更新」と「変更」の違い

 

在留期間更新は、同じ活動を続けるための手続きです。在留資格変更は、活動内容そのものが変わる場合に必要です。
この違いを誤ると、不許可や遅延の原因になります。

 

短期滞在からの変更について

 

原則として、観光目的の短期滞在から他の在留資格への変更はできません。多くの場合、一度帰国し、在留資格認定証明書を取得する必要があります。

 

まとめ

 

在留資格の変更は、タイミングを守れば決して難しい手続きではありません。
ただし、タイミングの誤りは不許可につながりやすいため注意が必要です。
少しでも不安がある場合は、申請前に専門家へ相談することをおすすめします。
