If you have built your life in Japan and are thinking about permanent residence or Japanese citizenship, the paperwork should not be the reason you put it off.
We handle permanent residence and naturalization applications from start to finish, entirely in English.
What we do
Permanent Residence (永住許可申請) For those who want to stay in Japan indefinitely without renewing their status of residence. We check whether you meet the requirements, prepare every document, and write the letter of explanation the Immigration Bureau expects.
Naturalization (帰化許可申請) For those who want to become Japanese citizens. The application runs to over a hundred pages and is reviewed by the Legal Affairs Bureau, not Immigration. We prepare the entire package and guide you through a process that typically takes around a year or longer.
Not sure which one is right for you? The two are different in almost every respect — nationality, voting rights, your original passport, and what is asked of you during the review. We will walk you through the difference before you commit to either.
Why this matters
Japan’s residency procedures are conducted in Japanese. The application forms are in Japanese. Notices from the Legal Affairs Bureau and the Immigration Bureau arrive in Japanese. When they ask for an additional document, that request comes in Japanese too.
You can be perfectly comfortable in daily conversation and still find yourself unsure what a form is actually asking for, or why a particular certificate is required at all.
We explain all of it in English — not through a translation tool. Our representative has worked in international contracts for around twenty years, in both English and Japanese, and holds Grade 1 of the EIKEN Test in Practical English Proficiency, the highest level of Japan’s national English certification.
One honest note about naturalization. Japanese citizenship requires Japanese language ability, at roughly the level of a Japanese elementary school third-grader in reading and writing. We can support you in English throughout the preparation, but we cannot remove that requirement. Permanent residence, by contrast, currently has no Japanese language requirement. However, a draft revision published in August 2026 proposes introducing a language requirement, though it is not yet confirmed.
What we handle, and what you handle
Collecting documents is not usually the hardest part. The hardest part is not knowing what applies to your situation, where a certificate is issued, or whether what you have gathered is enough.
We take care of:
- A document checklist built around your specific status of residence and family situation
- Obtaining certificates from Japanese government offices on your behalf — residence records, tax certificates, pension records
- Preparing the complete application package
- Writing the letter of explanation (permanent residence) and drafting the statement of motive (naturalization)
- Answering your questions throughout the review period
You take care of:
- Obtaining documents issued by your home country
- For naturalization: appearing at the Legal Affairs Bureau in person, and writing out the statement of motive by hand. Both are required by law and cannot be delegated. We prepare the draft; you write the final copy.
- For permanent residence: submitting the application at the Immigration Bureau
- For permanent residence: asking someone to act as your guarantor (a Japanese national or permanent resident)

How it works
- Get in touch. Use the contact form. Write in English.
- Free consultation (60 minutes). We go through your situation and tell you honestly whether an application is realistic, and what it would involve.
- Quote and engagement. If the plan makes sense to you, we begin.
- Documents and preparation. We gather what we can and prepare the full application.
- Filing. Naturalization is filed by you in person; we make sure everything is ready beforehand. For permanent residence, we prepare the complete package for submission.
- Review. Roughly a year for naturalization, longer for permanent residence. We stay with you for the whole of it, including any additional documents requested.
About
I am Shusaku Nakano, and I run this office alone.
I spent a year in the United States as a high school exchange student, and it was during that time that my interest in working across languages first took shape. With a background in law, I have since gained nearly twenty years of experience handling international legal matters in both English and Japanese.
Taking on a small number of cases at a time means I handle every one of them personally, from the first consultation through to the decision. You will not be handed to a different person partway through, and you will not have to explain your situation twice.
