This article explores the question of whether obtaining Japanese citizenship is an easy process. Eligibility requirements include living in Japan for at least five years, having a legal status of residence, being over 20 years old, speaking and understanding Japanese, having a stable income, and having no criminal record. The application process involves submitting various documents, undergoing an interview with immigration officials, and passing a written exam on Japanese language and culture. Dual citizenship is generally not allowed in Japan, and permanent residency is another option for those who do not meet the eligibility requirements or do not want to go through the application process. The article also highlights the impact on family members and cultural considerations that should be taken into account.
