Is Recording Phone Calls Legal in Japan After the 2026 Law Changes?

Yes, recording phone calls in Japan is legal under strict conditions, primarily requiring prior consent from all parties under the Telecommunications Business Act and Wiretapping Prohibition Act. Unilateral recording without disclosure risks civil liability and criminal penalties under Article 4 of the Wiretapping Prohibition Act, enforced by the Ministry of Internal Affairs and Communications (MIC). Recent 2026 amendments to the Act on the Protection of Personal Information (APPI) further tighten consent requirements for call recordings used in business contexts, mandating explicit opt-in mechanisms for customer data processing.

Key Regulations for Recording Phone Calls in Japan

  • Consent Requirement: All parties must be informed of recording under Article 4 of the Wiretapping Prohibition Act; failure to disclose constitutes illegal wiretapping, punishable by up to 2 years imprisonment or fines up to ¥500,000.
  • Business Compliance: The 2026 APPI amendments require companies recording calls for quality assurance to implement documented consent protocols, with the Personal Information Protection Commission (PPC) overseeing enforcement.
  • Data Retention Limits: Recorded calls must be stored securely for no longer than necessary under APPI guidelines, with mandatory deletion schedules audited by the MIC’s Telecommunications Business Department.

Violations trigger administrative orders, fines, or criminal prosecution, particularly if recordings involve sensitive personal data. Foreign entities operating in Japan must align with these standards or face penalties under the Act on the Protection of Personal Information.
