Several Japanese regulatory and advisory bodies have issued guidelines recommending DMARC adoption to combat phishing.
MIC requested telecommunications and internet service providers to implement DMARC at a policy of p=quarantine or p=reject.

Read moreYahoo Japan recommends DMARC and domain authentication for users, issuing a warning that non-compliant messages may be marked as spam or rejected.
Read moreAs the top targets for phishing, financial firms are directly addressed by the JSDA's guidelines. Moving to a p=reject policy is a critical step to protect customer accounts from fraud and meet industry standards.
With Japan's push toward “Society 5.0,” securing digital services is a priority. While DMARC is not universally mandated, it is a key measure for protecting public trust and preventing the impersonation of government agencies.
The supply chain is a frequent target of Business Email Compromise (BEC) fraud. Implementing DMARC helps secure communications with partners and customers, protecting against invoice fraud and operational disruptions.
The healthcare sector handles sensitive patient data, making it a prime target for cybercriminals. DMARC enforcement helps prevent attackers from spoofing hospital domains to steal personal information or send fraudulent billing notices.
PowerDMARC and our Japanese partners offer a managed service with a phased approach to safely take your domains from a passive monitoring policy to full enforcement.
We identify all your sending domains and subdomains, and deploy DMARC at p=none to begin collecting data.
Our team analyzes DMARC reports to identify all legitimate sending sources, including third-party ESPs and SaaS vendors. We then work to align their SPF and DKIM records.
We shift your policy to p=quarantine using a gradual percentage-based rollout. This allows us to monitor for any legitimate mail streams that need correction without impacting delivery.
After confirming that all legitimate mail is authenticated, we move your policy to p=reject. We also configure policies for parked domains and help you deploy BIMI and MTA-STS for complete protection.
PowerDMARC is a complete email authentication platform designed for the needs of Japanese companies.

Perfect Japanese Language Support Makes Security Management Easy
What I like best about PowerDMARC is its full support for the Japanese language. For Japanese users, navigating complex security settings can be challenging, so having the interface in Japanese is a huge advantage. It makes the platform much more accessible and easier to manage compared to other tools.

While not a universal legal mandate, DMARC is strongly recommended by the MIC, JSDA, and the Anti-Phishing Council. It is becoming a standard expectation for any organization that wants to secure its email, protect its brand, and align with cybersecurity best practices in Japan.
These bodies recommend that organizations implement a DMARC policy of p=quarantine or p=reject. Their goal is to encourage a move away from passive monitoring to active enforcement to block phishing and other email-based attacks effectively.
The goal should always be to reach p=reject. A p=none policy provides visibility and is a great starting point, but it does not stop fraudulent emails. To protect your customers and brand reputation from rising phishing threats, an enforcement policy of p=quarantine or p=reject is essential.
With a managed platform like PowerDMARC, most organizations can safely transition to a p=reject policy in record time. The process is managed in phases to ensure that no legitimate business emails are accidentally blocked.
