Naturalization Application

About naturalization application

Naturalization application means that a foreigner who has been shown his intention to acquire Japanese citizenship will apply to the Minister of Justice and acquire Japanese citizenship and become a “Japanese”.Since Japan does not recognize dual citizenship, obtaining Japanese citizenship means losing its original nationality.In addition, because the dual nationality of the minor also has to choose the nationality by the time it reaches adulthood, the indication of the intention to become a Japanese becomes a naturalization application.However, naturalization applications are not easily accepted, and it takes time to apply.Since this is the situation surrounding such a naturalization application, the Well Administrative Scrivener Legal Office has interviewed in advance and has received requests after considering it.

Conditions for naturalization application

Article 5 of International Law
1) Continue to have an address in Japan for more than five years
By the time you apply for naturalization, you have been in Japan for more than five years.The address here is a “base of life”, so it is important to be careful because it does not include a mere “place of residence”.
However, a person who has an address or residence in Japan for more than three years in the child of a Japanese national (excluding adopted children)
This condition is waived in cases such as (Article 6,1 1 of the Nationality Act).

2) Must be at least 20 years of age and have the ability under the home law (reaching adulthood)
“Having the ability by the law of the home country” is that it has reached adulthood by the law of the United States of America, for example.However, a foreigner who is the spouse of a Japanese national and has three years from the date of marriage and has an address in Japan for more than one year.
This condition is waived in cases such as (article 7, the second stage of the Nationality Act).In addition, when a minor makes an application, the conditions are cleared because if the parent makes a naturalization application, it becomes a “child of the Japanese people” when the naturalization of the parent is permitted.

3) Good conduct
It is said that it is not inferior to a usual Japanese line.It is necessary to be careful even if it is a previous department, the delinquency history, and the traffic violation.
It is also important to have proper income declarations and tax obligations that are easy to forget.

4) To make a living by the assets or skills of a spouse or other relative who makes a living as one person or another.
Naturalized applicants must be able to make a living by their spouse or other relatives who make the same living.Even parents who are supported by their spouses (husbands and wives) and who are dependent on their children are required to make a living by comprehensively judging the assets or skills of their relatives who make a living.

5) Never attempted or carried out sabotage against the government
There are naturally no conditions for such a person because it is embarrassed by the person who makes anti-social acts and claims such as the destruction of the constitution and the government with violence after the date of the enforcement of the Constitution of Japan.Moreover, the person who formed and joined the organization which makes these claims and acts is not admitted, but I think that it is possible to judge it if it thinks about this condition in common sense.

6) You must not have nationality or lose that nationality by acquiring Japanese nationality.
A naturalized applicant must be a “stateless person” or a Person who loses his or her previous nationality by obtaining Japanese nationality.However, there are exceptions that can not be taken in fact, such as countries and refugees who do not allow minors to lose their nationality, but there are also nationality laws that allow them to leave their nationalities when there are special circumstances.
