Dual Nationality in Japan

Abstract

In March 2018, eight plaintiffs, Japanese nationals residing in Europe, filed a lawsuit against the Japanese Government at Tokyo District Court. Six of them were, according to article 11 Nationality Law, forced to renounce their Japanese nationality upon acquiring foreign nationality and want to restore their Japanese nationality. The other two claim to have lost job opportunities by reason of the deterrent effect of naturalization abroad. Hence, this lawsuit, the first of its kind, has reopened the complex debate on dual nationality. This Paper examines Japan’s stance on dual nationality. First, the concept of ‘dual nationality’ will be discussed. Secondly, one will delve into the history of the Japanese nationality legislation in order to unravel Japan’s current policy on dual nationality. Thirdly, the factors which most feasibly explain Japan’s unwillingness to change its policy will be scrutinized. Lastly, a conclusion will be formulated.
