Tokyo Court: Hiding Marriage in App Dating Violates ‘Chastity Right,’ Awards ¥1.5 Million

The judgment frames marital concealment as undermining a person's autonomy to choose intimate partners under Japanese civil law.

Overview

  • The Tokyo District Court ruled on December 8, 2025 that a man who concealed being married during an app-based relationship infringed the woman's chastity right.
  • The court ordered the defendant to pay about ¥1.5 million in damages after the plaintiff sought roughly ¥7.8 million.
  • According to the ruling, the pair met on a matching app in 2023, and the man said he was single when asked about his marital status.
  • The couple dated for about four months and had multiple sexual encounters during that period, as outlined in the case record.
  • Reports identify the plaintiff as an employee at a foreign-affiliated company and the defendant as working at a major advertising firm.
