“I’ve lived in Japan for many years and now want to obtain Japanese citizenship.”

If you are considering naturalization in Japan, Office Ishinagi is here to support you every step of the way. As an administrative scrivener office with extensive experience in residence and nationality procedures, we will help make the complex naturalization process more understandable and manageable.
What Is Naturalization?
Naturalization is the legal process in which a foreign national obtains Japanese citizenship with the permission of the Minister of Justice. Those who have been living stably in Japan, paying taxes, and meeting certain behavioral and residency requirements may qualify for naturalization.
Benefits of Naturalization
- No longer need a visa or residence status renewals
- Can obtain a Japanese passport
- May benefit your children’s education and future prospects
Possible Drawbacks
- Generally requires renouncing your original nationality
- Screening process can take 6 months to over a year

Examples of individuals who may be eligible:
- Have lived in Japan continuously for 5 years or more
- Married to a Japanese national for 3+ years and living in Japan for at least 1 year
- Children born and raised in Japan

There are also special cases such as minor children applying with a parent, or individual applications by minors born in Japan. We handle each case carefully according to your situation.
