dmarcian Releases Guidance for the Japanese Market: The Role of DMARC in an Evolving Regulatory Environment

【FOR IMMEDIATE RELEASE】 dmarcian, a global leader in DMARC platforms and services, today released new technical and regulatory guidance for Japanese domain owners titled 'How DMARC Helps Japanese Domain Owners Demonstrate Compliance.' This guidance explains how Japanese companies, government agencies, and critical infrastructure operators can navigate rapidly evolving cybersecurity regulations and how DMARC serves as a robust foundation for compliance. Due to the surge in phishing attacks targeting Japan, the 'language barrier' that once acted as a natural defense has effectively disappeared. In 2025, financial losses from unauthorized internet banking transfers reached a record high of 10.4 billion yen. DMARC has become an essential measure within Japan's regulatory environment, including METI guidelines, government standards, the APPI, and the Active Cyber Defense Act. Masahiro Otsuka, APAC Business Development Manager at dmarcian, emphasizes that individual companies adopting DMARC is crucial to ensuring the effectiveness of legal frameworks.
