Special Cases: Shorter Requirements

Not everyone needs 10 years. Some groups have shorter requirements:

Spouse of Japanese Citizen (日本人の配偶者)

Child of Japanese Parent

Former Japanese Citizen

⚠️ Yamada Hack: Even if you qualify for shorter requirements, you still need perfect tax and insurance records. The "spouse shortcut" is not easy — prepare 2+ years of documents.
