The Tokyo High Court has filed a lawsuit following the first trial, claiming that it is unconstitutional that people who have acquired foreign nationality but lost Japanese nationality are not allowed to have dual nationality under the provisions of the Japanese Nationality Law. and refused to accept dual citizenship.
Eight people, including those who lived in Switzerland and Liechtenstein and acquired local nationality but lost Japanese nationality, complained that ``not allowing dual citizenship violates the constitution that stipulates respect for individuals.'' I was asking for confirmation that I have Japanese nationality.
The Japanese Nationality Law stipulates that if a person acquires a foreign nationality at their own request, they lose their Japanese nationality, and it does not allow people to have multiple nationalities.
The Tokyo District Court in the first instance pointed out that ``the provisions of the Nationality Law prevent the occurrence of dual nationality as much as possible while also guaranteeing the freedom to change nationalities,'' and dismissed the lawsuit, judging that it did not violate the Constitution. Therefore, the plaintiff appealed.
In the ruling of the second trial on the 21st, presiding judge Nobuaki Iwai of the Tokyo High Court, following the ruling of the first trial, dismissed his appeal and did not recognize dual citizenship.
About three quarters of the countries in the world allow dual citizenship, and the court's decision was attracting attention.
