■ Naturalization Process Outline
Naturalization in Japan is the process by which a foreign national can become a Japanese citizen. In general, the process is quite strict and requires several years of residency in Japan, as well as meeting other eligibility criteria.
To be eligible for naturalization in Japan, a foreign national must have at least 10 years of residency in Japan (or three years for those who are married to a Japanese citizen). They must also be at least 20 years old, have a good understanding of the Japanese language, and have no criminal offence record. In addition, they must be willing to renounce their current nationality and take an oath of allegiance to Japan.
The application process for naturalization in Japan involves submitting various documents, including a written application, proof of residency in Japan, proof of income, and other certificates proving the facts that the applicant has been fulfilling public duties. Applicants must also undergo several times of interviews with which Japanese language ability will be examined.
The Japanese government reviews each application carefully, and the process will take more than one year months to complete. If the application is approved, the foreign national officially become a Japanese citizen. It's worth noting that dual citizenship is not allowed, meaning that it is required for every individual who naturalized in Japan must give up their previous citizenship.
