Dupla nacionalidade/subcidadania bilateral — nenhuma (positivo N/A)
Cidadania em Japan
- Elegibilidade
- O Japão proíbe a dupla nacionalidade de adultos e não faz parte de nenhum instrumento de nacionalidade bilateral do tipo CTA/Benelux. Ausência confirmada (não tratado + MOFA).
- Renúncia
- Não exigida
Quem se qualifica
- Positive N/A — Japan is party to no bilateral jus-sanguinis dual-nationality treaty; the Nationality Act imposes the nationality-selection duty (Arts. 14-16) universally without bilateral carve-outs, so there is no treaty-based dual-nationality route.

Cenários de exemplo
Os cenários de exemplo são exibidos em inglês.
There is no bilateral dual-nationality or citizenship treaty between Japan and North Korea (or any other country). Japan is party to no CTA/Benelux-style bilateral nationality instrument. The positive N/A (JP-BIL-01) applies: Japan's nationality selection duty (Arts. 14-16) applies universally without bilateral carve-outs. Keiko's sister cannot acquire Japanese nationality through Keiko's sibling relationship — adult siblings are not a basis for any Japanese nationality acquisition route. If the sister wanted to pursue Japanese nationality, she would need to independently qualify through her own merit (naturalization: 5-year domicile in Japan, etc.). Keiko's Japanese nationality is irrelevant to her sister's eligibility.
No Japan-North Korea bilateral nationality arrangement (JP-BIL-01: positive N/A) | No sibling-based route in Japanese nationality law | Sister's path requires independent eligibility under Nationality Act
