Naturalization System
Naturalization refers to the legal procedure through which a foreign national acquires Japanese nationality. It is stipulated in Japan's Nationality Act, and by obtaining permission from the Minister of Justice, one gains the rights and obligations as a Japanese citizen. Under the current Nationality Act, the general residency requirement for foreign nationals applying for naturalization has primarily been "continuously residing in Japan for five years or more." In addition to this, other requirements include being 20 years of age or older (capacity requirement), being able to support oneself or one's family (livelihood requirement), having no criminal record and abiding by the law (conduct requirement), not plotting to violently overthrow Japan's constitution or government, nor belonging to such organizations (thought requirement), and principally renouncing one's original nationality (prevention of dual nationality requirement). This recent announcement concerns the tightening of this residency requirement from the conventional "five years or more" to "principally ten years or more," effectively raising the hurdle for acquiring Japanese nationality. This reflects the government's stance requiring applicants to integrate more deeply into Japanese society over a longer period, understand Japanese culture and values, and fulfill obligations such as paying taxes. For instance, Germany generally requires an 8-year residency period, along with completion of an integration course and specific language proficiency (B1 level). Japan's move can be interpreted as steering towards requiring deeper commitment, aligning with standards in other countries.
Nationality Act
The Nationality Act is a law that defines the fundamental matters concerning the acquisition, renunciation, and restoration of Japanese nationality. This law is extremely important as it stipulates the relationship between the state and individuals by clarifying the scope of citizens, thus pertaining to national sovereignty. Since its enactment in 1899, it has undergone several significant revisions. For instance, in 1950, after World War II, it changed from the previous "patrilineal principle" (a child acquired Japanese nationality if the father was Japanese) to the "bilateral principle" (a child acquired Japanese nationality if either parent was Japanese). Furthermore, in 1984, revisions were made to relax the requirements for acquiring nationality. Most recently, in 2008, amendments were made to address issues regarding the acquisition of nationality by non-marital children. The tightening of "naturalization" requirements announced this time is viewed as a change in the application of the "residency requirement" stipulated in Article 5 of the Nationality Act, or an announcement made with future legislative amendments in mind. The purpose of the Nationality Act is to clarify the scope of citizens and define the subjects of citizens' rights and obligations. At the same time, its application is constantly subject to debate from various perspectives, such as Japan's position in the international community, national security, and the maintenance of social order. This tightening can be understood as part of a movement to reconstruct the nation's standards for granting nationality, against the backdrop of changing national interests and public sentiment.
Residency Requirement
The residency requirement is a condition that foreign nationals must continuously reside in Japan for a specified period when applying for Japanese nationality (naturalization). This is the core part of the current article, announcing that the conventional principle of "continuously residing in Japan for five years or more" (Article 5, Paragraph 1, Item 1 of the Nationality Act) will be tightened to "principally ten years or more" from next month. This residency requirement is considered an important indicator for judging whether applicants have sufficiently adapted to Japanese society, understood Japanese culture and lifestyles, and established a stable livelihood. A longer period of residence tends to be regarded as demonstrating a higher degree of contribution and integration into Japanese society, especially in terms of acquiring Japanese language proficiency, participating in local communities, fulfilling tax obligations, and contributing to social security systems. In recent years, with the expansion of accepting foreign human resources, there have been some criticisms regarding social problems after short-term residents acquire nationality or a lack of recognition of the weight of citizenship. Against this backdrop, there was likely a growing call for more cautious screening and a deeper commitment to Japanese society. Internationally, for example, acquiring U.S. citizenship requires 5 years of residence after obtaining a green card, and the UK also generally requires 5 years, but Germany requires 8 years, and Switzerland 10 years, varying by country. Japan tightening to "10 years or more" is not exceptionally strict compared to other countries; rather, it could be said to align with international standards in emphasizing the "bond between the state and its citizens." However, there are relaxed special provisions for those such as spouses of Japanese nationals, those born in Japan, or special permanent residents, and the impact of this tightening on these special provisions will require awaiting further detailed announcements.
