Reiwa 6 (Wa) No. 11438 Compensation for Damages Case

In 2025, a Zainichi Korean resident filed a damages lawsuit in Tokyo District Court against a Japanese activist for repeated online hate speech and defamation targeting ethnic Koreans. The plaintiff sought ¥5 million in compensation for emotional distress, citing violations of Japan Hate Speech Elimination Act and the Civil Code. The defendant argued his statements were protected under freedom of expression. The case drew attention as a test of Japan relatively new hate speech legislation and its application to online platforms. The court examined whether the defendant posts constituted unlawful discrimination and defamation under Japanese law, considering the balance between constitutional free speech rights and the protection of minority groups from racial vilification. This case was one of several civil actions emerging from rising anti-Korean sentiment on social media platforms in Japan during the mid-2020s.

In a partial ruling delivered in early 2026, the Tokyo District Court found the defendant liable for defamation, ordering him to pay ¥1.2 million in damages and issue a public apology. The court held that the defendant statements exceeded the bounds of protected speech by inciting hatred against a specific ethnic group. An appeal is pending.

Whether online hate speech targeting ethnic minorities constitutes actionable defamation and illegal discrimination under Japanese civil law, and how to reconcile freedom of expression protections under Article 21 of the Japanese Constitution with the rights of ethnic groups to live free from racial hostility.

The case significantly impacted public discourse on hate speech regulation in Japan. It strengthened enforcement of the Hate Speech Elimination Act and prompted social media platforms to enhance content moderation for ethnic harassment. Korean residents advocacy groups viewed it as a milestone in combating racial discrimination. The ruling also sparked debate on constitutional free speech limits, with some legal scholars arguing the decision might chill political expression concerning Japan-Korea relations. Internationally, it drew attention to Japan treatment of ethnic minorities and its compliance with human rights standards on non-discrimination.
