A growing number of foreign nationals are opting to acquire Japanese citizenship through naturalization rather than applying for permanent residency — largely because the former is conversely easier to obtain under current laws, much to the chagrin of some policymakers. In Japan, naturalization requires five years of residency, while permanent residency requires 10. A background check for naturalization typically looks at just one year of tax and insurance payments, compared to five years of tax and two years of insurance history for permanent residency applicants. Justice Minister Keisuke Suzuki acknowledged the discrepancy during a parliamentary session in May, saying it would be "clearly inappropriate" if naturalization were the easier path. "Both pathways should involve strict evaluations," he said, adding that the government would review the legal framework for consistency. Nippon Ishin's Yanagase, who raised the issue, said the current system lacks coherence and called for legislative changes. "Naturalization grants voting rights and access to one of the world's most powerful passports. It should not come with lighter requirements than permanent residency," he said.
