Japan MIC Certification for Wireless & IoT Devices

MIC certification is Japan’s mandatory conformity approval under the Radio Law and the Telecommunications Business Law. It applies to all wireless transmitters, IoT modules, and telecom devices marketed in Japan. Certification ensures compliance with requirements for radio frequency emissions, spectrum allocation, safety, and interoperability.

Approval is typically granted by a Registered Certification Body (RCB), often referred to as “Telec approval.” Without MIC certification, wireless and IoT products cannot be marketed or connected to Japanese telecom networks.

Depending on the product, Japan certification may involve:

• Radio Law Certification – required for all wireless transmitters (Wi-Fi, Bluetooth, Zigbee, cellular, RFID, 5G, etc.);

• Telecommunications Business Law (TBL) – applies to devices connected to public networks;

• SAR / RF Exposure Testing – ensuring compliance with human exposure limits;

• Labeling Requirements – devices must carry the correct “Technical Conformity Mark” before market entry.

At IoT Consulting Partners, we support clients through the entire MIC certification process:

• Pre-Testing & Debugging – verifying RF performance before formal testing;

• Accredited Lab Testing – coordinating Radio Law and TBL testing in approved laboratories;
