Interview during Application for Naturalization Permit\When can you expect to be notified of the results after the interview?

When you apply for a naturalization permit in Japan, one of the mandatory steps is an interview. After the interview, it may take some time before the results are announced. Some people worry because they do not know what to do after applying for the naturalization permit, or because they want to know what to look for after the interview. This topic is about the interview for naturalization application, interview time, and other basic information.

About the interview for the naturalization application

An interview is held approximately 2 to 4 months after the naturalization application is submitted. All applicants older than 15 years are interviewed.

It takes place on weekdays, but the time and content of the questions vary depending on the applicant.

During the interview, it is verified that the documents submitted are true, that the documents match the applicant’s current situation, and that the applicant has sufficient Japanese language skills to live as a Japanese citizen.

Common questions are:

  • About the family in the home country and the Japanese family
  • Reason for acquiring Japanese citizenship
  • About your current residence (do you own a house, are you a tenant, etc.)
  • Work history, reasons for changing jobs, current employment, etc.
  • Previous marriages and the presence or absence of children
  • Comparison of pay slips and income and expenses, future prospects, etc.
  • Payment of pension contributions, taxes, etc.
  • Frequency of return to home country, etc.
  • If there is a cohabitant who is not a family member, the relationship and income with that cohabitant
  • Driving record

Since the purpose of naturalization varies depending on the applicant, the content of the interview is adapted to the specific situation of the applicant.

Livelihood requirement

The livelihood requirements are usually examined very carefully. For example, whether you pay your taxes properly and whether you pay into the public pension system.

  • Japanese language proficiency

To live in Japan, it is important that you can read, write and speak Japanese.

Generally, Japanese language proficiency equivalent to the third grade level of elementary school is required, but depending on the applicant’s level, a Japanese language test may also be administered.

If you feel unsure of your Japanese skills, it would be a good idea to study in advance.

Interview time and basic information

Some interviews are completed in 30 minutes, while others can take up to 2 hours.

In some cases, you may be asked to bring a person close to you if it is determined that they have a significant impact on your life in Japan.

There is no specific dress code, so you can wear whatever you like. However, appearance can also influence judgment, so it is important to make a good impression.

After the interview, you will be notified of the results in about 6 to 10 months.


During the interview for approval of naturalization, it is verified that the documents submitted are true, that the applicant’s situation and documents are coherent, and that the applicant has the Japanese language skills to be recognized as Japanese.

However, since the purpose of naturalization varies from applicant to applicant, the content of the interview is tailored to the situation of each applicant. In general, very careful consideration is given to whether the applicant meets the livelihood requirement.
