Case for Revocation of the Decision to Dismiss the Objection to Non-Registration on the Electoral Register

In early 2026, Park Yong-gi, a South Korean national who has permanently resided in Shinjuku, Tokyo for over thirty years, attempted to register on the electoral roll for the upcoming Tokyo gubernatorial election. The Shinjuku Ward Election Administration Commission refused to register him solely on the ground that he is not a Japanese national. Park filed an objection under the Public Offices Election Act, but the Commission dismissed it. He then filed a lawsuit before the Tokyo District Court seeking revocation of that dismissal decision, arguing that the blanket exclusion of permanent foreign residents from local elections violates the principles of equality under Article 14 and the guarantee of the right to choose public officials under Article 15 of the Constitution, and contravenes international human rights standards. The case became a focal point for the long-standing debate on foreign suffrage in Japan.

In August 2026, the Tokyo District Court dismissed the claim, ruling that the Constitution implicitly reserves the right to vote for public officials to Japanese nationals and that the nationality restriction in the election law is a reasonable exercise of legislative discretion. The court also stated that extending suffrage to foreign residents is a matter for political decision, not judicial mandate. Park's legal team announced an immediate appeal to the Tokyo High Court.

Whether the refusal to register a permanent foreign resident for local elections, based strictly on a nationality requirement in the Public Offices Election Act, is unconstitutional as a violation of the right to equality and the right to participate in local governance; and whether the legislature's discretion to limit suffrage to Japanese nationals is rationally related to a legitimate state interest.

The ruling reignited heated public debate on multicultural coexistence and the political rights of nearly one million permanent foreign residents in Japan. South Korean diplomatic circles expressed concern, viewing it as a setback for the rights of the Korean diaspora. Civil society groups organized protests and petition drives calling for legal reform, while conservative voices welcomed the decision as a defense of national sovereignty. The case further strained Japan-South Korea relations and prompted renewed parliamentary discussion on a potential local referendum law that could bypass the nationality barrier.
