​Naturalization in Japan (Okayama): Overview, Timeline & Common Pitfalls

This page provides a general overview of naturalization (Japanese citizenship) in Japan.
Naturalization is handled through the Legal Affairs Bureau (nationality procedures), not the Immigration Services Agency.
Because requirements and required documents vary by individual circumstances, we do not list “every document for every case” here.

Note : This page provides general information and does not replace official instructions or legal advice.

Who this page is for

This guide is helpful if you:

  • are considering Japanese citizenship and want the big picture first

  • want to plan your timeline realistically

  • want to avoid common issues that delay the process

  • prefer support in English

Child Touching Globe

The first step (important)

In many areas, nationality consultations (including naturalization) are appointment-based and handled by the Legal Affairs Bureau with jurisdiction over your address.


Please use the official contact list to find the right office.

Basic requirements (high-level)

Naturalization permission is considered based on conditions set in Japan’s Nationality Act.
Common themes include:

  • residence history in Japan

  • good conduct / compliance

  • stable livelihood

  • Japanese language ability

  • (in principle) avoiding dual nationality after approval

This is intentionally simplified. Requirements vary significantly depending on your background.

Typical timeline (general)

A common planning flow is:

  1. appointment and preliminary consultation at the Legal Affairs Bureau

  2. collecting documents (often the longest part)

  3. preparing application documents and explanations

  4. submission and follow-up communication/interview(s) as instructed

  5. decision and next steps

Common mistakes that cause delays

  • starting too late and underestimating document collection time

  • inconsistencies across documents (names, addresses, dates, job history)

  • unclear explanations for changes (job changes, travel, family situation)

  • not preparing for what the bureau will ask in consultation/interviews

​FAQ

Q1. Is naturalization the same as permanent residency (PR)?
No. PR is a residence status; naturalization is Japanese citizenship.

​

Q2. Can I just submit everything online?
Naturalization procedures are handled through the Legal Affairs Bureau. Please confirm the exact method with your competent office using the official contact list.
