However, how to get Japanese citizenship is a question that requires deep study, especially given the changes that came into effect in 2026.

Key Requirements for Japanese Citizenship by Naturalization

To qualify for citizenship Japan, you must meet a number of conditions outlined in Article 5 of the Nationality Act. It is important to understand that fulfilling these conditions is only a minimum threshold, and the final decision rests with the Minister of Justice. This applies to everyone interested in how to get Japanese citizenship.

Residency Period in Japan: A Key Condition for Obtaining Citizenship

As of April 1, 2026, the Japanese Ministry of Justice, as part of its “social integration” requirement, effectively expects candidates to have at least 10 years of legal and continuous residency in the country. Formally, the law still specifies 5 years, but in practice, applications with a shorter residency period are almost certain to be rejected. This is an important condition for those planning naturalization Japan.

• Continuity of Residence: It is important that your stay is legal and not interrupted by long absences. Trips abroad for more than 3 months (about 90 days) usually interrupt the period, and the countdown starts anew.
• Permissible Absences: Up to 100 days abroad per year are considered safe. Between 100 and 150 days may require explanation, and absences exceeding 150 days may result in the period not being recognized as continuous.
• Travel History: From 2026, the 法務局 (Legal Affairs Bureau) thoroughly checks travel history for the past 10 years, requiring copies of all passports with stamps.
• Visa: At the time of application, it is recommended to have a long-term visa (for 3 or 5 years), as applications with an annual visa are usually not accepted.

Age and Legal Capacity for Japanese Citizenship

A candidate wishing to obtain Japanese citizenship must be over 18 years old (as of April 1, 2022) and be legally competent under the laws of their country. Children can apply for citizenship with their parents.

Good Conduct (素行善良)

This condition implies no problems with the law, such as criminal records, visa violations, or unpaid taxes and contributions. Even numerous traffic violations can be a reason for refusal of citizenship.

Financial Stability when Obtaining Citizenship

You must be able to support yourself or your family. The minimum income amount is not legally established, but practicing lawyers rely on the following indicators when considering applications for Japanese citizenship:

• For one person: approximately 3 million yen per year (180–200 thousand yen per month net).
• For a family: the balance of income and expenses is important, not a specific figure.
• Full-time employment (正社員) is preferred. Contract work or agency work is possible with stable experience.
• After changing jobs, it is recommended to wait 6–12 months. Transitioning to freelance during the review may lead to rejection.
• Mortgages and student loans are not a problem if payments are made on time. Debts disproportionate to income, or expenses exceeding income, are a problem.
• For business owners: a profitable company without negative capital, director’s salary of 180–250 thousand yen per month, employees must be enrolled in 社会保険 (social insurance).

Renunciation of Previous Citizenship: A Key Step for Japanese Nationality

Japan does not recognize dual citizenship for adults. When obtaining Japanese citizenship, you must renounce your previous nationality. Exceptions are possible only in cases where the country of origin does not provide an opportunity to renounce citizenship for reasons beyond the individual’s control.

• For Russians: how to get Japanese citizenship for a Russian involves submitting an application to renounce Russian citizenship through the consulate, which is a lengthy process and is planned in parallel with the Japanese application.
• For Belarusians and Ukrainians: how to get Japanese citizenship for a Belarusian and how to get Japanese citizenship for a Ukrainian also requires the procedure of renouncing citizenship through the respective diplomatic missions.
• For Kazakhs: how to get Japanese citizenship for a Kazakh is often simpler, as Kazakh citizenship is automatically lost upon obtaining foreign citizenship.

No Attempts to Overthrow the Constitution by Force

For most candidates, this is a formality, but it is a mandatory requirement when applying for citizenship Japan.

Japanese Language Proficiency and Social Integration for Citizenship

The Ministry of Justice requires Japanese language proficiency sufficient for daily life: speaking, reading, and writing. Officially, JLPT levels are not required, but an N4 certificate or higher will be a plus. This is an important aspect for those who want to get Japanese citizenship.

• Interview Check: Language skills are tested during an interview, where questions about family, work, and motivations are asked — all in Japanese.
• Written Test: If the interviewer has doubts, a written test may be offered (reading kanji, translating between hiragana, katakana, and kanji, short texts).
• Autobiography and Motivation Letter: These documents must be handwritten in Japanese.

Taxes, Pension, and Health Insurance: New Requirements for Citizenship in 2026

As of 2026, requirements for paying taxes and contributions have become stricter when considering applications for Japanese citizenship. They check not only the payment itself but also its timeliness.

Important: Delays in paying taxes and contributions within the checked period are now a frequent reason for refusal of citizenship. If taxes and contributions are withheld from your salary, you do not need to confirm dates. If you pay yourself, keep all receipts.

Japanese Citizenship Application Process: A Step-by-Step Plan

Immigration to Japan and obtaining citizenship is a lengthy process that can take 6 to 8 years of preparation and up to 1.5 years after application submission.

1. Preliminary Consultation: Begins with a consultation at the Legal Affairs Bureau (法務局) in your area of residence. Here, you will be provided with an individualized list of necessary documents for obtaining Japanese citizenship.
2. Document Collection: This stage can take 2 to 6 months, as it requires collecting many certificates, including tax returns for 5 years and pension contributions for 2 years.
3. Application Submission: The application is submitted in person, without proxies, within Japan.
4. Review and Interview: After submitting the application, a thorough review begins, which may include calls to employers, neighbors, and the tax office. After 8–12 months, an interview is conducted where the interviewer asks questions about your motivations, daily life, and plans for living in Japan.
5. Approval and Renunciation of Previous Citizenship: After your application is approved, which is published in the official gazette, you will need to go through the procedure of renouncing your previous citizenship. Relocation and all related legal issues become particularly relevant at this stage.
6. Processing Japanese Documents: After renouncing your previous citizenship, a family register (koseki) is created, a Japanese passport is issued, and you surrender your resident card.

Special Cases: Reduced Naturalization Periods for Citizenship

Some categories of applicants may qualify for Japanese citizenship through a simplified procedure with reduced residency periods.

How to get Japanese citizenship by marriage is one of the most frequent questions. The spouse of a Japanese citizen can apply after 3 years of residency in Japan or after 3 years of marriage, if they have lived in Japan for at least one year of that period. However, marriage itself does not grant citizenship; the procedure and vetting remain as strict as for other categories wishing to get Japanese citizenship.

Conclusion: How to Get Japanese Citizenship in 2026

How to get Japanese citizenship in 2026 is a question that requires serious preparation, patience, and compliance with strict Japanese legal requirements. Given the latest changes, especially regarding residency periods and timely tax payments, the process has become even more demanding. However, for those willing to embark on this path, Japanese citizenship opens doors to one of the most developed and safest countries in the world, offering broad opportunities for travel and life. Business immigration or moving to Japan is a serious step that requires careful planning and understanding of all the nuances of Japanese citizenship requirements.
