Japan Radio Law (TELEC/MIC) Type Approval
1 resources tagged with "Radio Law"
Any electronics from China that transmit radio — Wi-Fi, BLE, LoRa, 2.4GHz remotes — need TELEC/MIC type approval under Japan's Radio Law (電波法) before they can be sold or even legally operated in Japan. The technical conformance follows ARIB standards (for example ARIB STD-T66 for 2.4GHz wideband systems), and the Giteki (技適) mark with its certification number must appear on or in the device.
When you source a radio module, check whether it already carries Giteki certification — pre-approved modules (common with ESP32 and Nordic parts) let you inherit the approval instead of testing the whole product. The common pitfall is assuming an FCC/CE module is automatically Japan-legal; it is not, and shipping unapproved transmitters into Japan exposes the importer to liability.

FAQ
Does my product need TELEC certification if the module already has Giteki?
If you use a pre-certified module unchanged and follow its antenna and integration conditions, you can usually inherit its Giteki approval rather than re-test. Changing the antenna, RF path, or firmware power settings can void that inheritance.
How long and how much does TELEC/MIC type approval take?
Module-level type approval typically runs a few weeks at a Registered Certification Body and often costs in the low thousands of USD, depending on the number of bands and modes. Plan it before mass production, not after.
