Japan’s MIC Opens Consultation on 433 MHz Band Wireless Devices

The Ministry of Internal Affairs and Communications (MIC) in Japan has launched a public consultation, starting on September 7, 2024. The consultation focuses on a draft report from the Land Radio Communications Committee, which outlines specific technical requirements for tire pressure monitoring systems (TPMS) and remote keyless entry systems operating in the 433 MHz band. This is part of broader guidelines designed to regulate low-power radio systems in Japan. The public is invited to provide comments on the draft until October 7, 2024.

 

Importance of the Consultation

The 433 MHz band plays a vital role in ensuring the reliable operation of various low-power devices, including TPMS and remote keyless entry systems. These systems are crucial for both automotive safety and consumer convenience. Given their growing use in modern vehicles, the consultation aims to ensure that Japan’s regulatory framework remains up-to-date with global technological advancements.

 

MIC Certification and Giteki Mark: Entry Requirements for Wireless Products in Japan

To enter the Japanese market with wireless products, manufacturers must comply with MIC certification standards and obtain the Giteki mark, which certifies that a device meets Japan’s radio frequency regulations. The certification process depends on the type of wireless equipment, and Japan distinguishes between Specified Radio Equipment (SRE) and Special Specified Radio Equipment (SSRE).

For SSRE, the certification process is simplified. Manufacturers can submit a declaration of conformity along with properly prepared test reports through a Japan-based representative. This ensures that products meet the required technical standards without extensive testing. However, for SRE, testing must be carried out by a Registered Certification Body (RCB), and the approval process is more detailed, especially for products to be sold in large quantities.

  • Type Certification: For mass-produced equipment, only sample devices undergo testing by the RCB. Once approved, manufacturers are responsible for marking the products with the Giteki label.
  • Small Batch Testing: For smaller quantities, each product must be tested and marked by the RCB.

 

Testing and Certification Support for Low-Power Devices

In addition to the standard regulatory requirements, voluntary schemes are available for testing High-Frequency Devices and Extremely Low-Power Devices. These testing protocols help ensure that devices operate safely within designated frequency bands without causing interference. Testing services and certification processes can be fully managed by service providers, ensuring a smooth approval process for wireless products in Japan.
