Japan’s Ministry of Internal Affairs and Communications (MIC) has announced a partial amendment (ref. G/TBT/N/JPN/840) relevant to TPMS and RKE equipment.
What’s changing:
- - Frequency band expansion: TPMS and RKE devices would be allowed to operate in 433.05–434.79 MHz, with adoption planned for June 2026.
- - Simplified requirements: Current conditions tied to the equipment enclosure would be eliminated under the revised Radio Equipment Regulation and related Public Notice.
