Which process is managed by Ministry of Internal Affairs and Communications in Japan?

The correct answer isRF technical standards. In Japan, wireless LAN and other radio equipment must operate under national RF regulatory requirements controlled by the Ministry of Internal Affairs and Communications, commonly referenced as MIC. TELEC, a registered certification body in Japan, states that specified radio equipment such as wireless LAN equipment used in Japan must conform to technical regulations regulated by MIC, and that radio equipment conformity certification validates conformance to the technical standards under Japan’s Radio Act.

This aligns directly with Cisco wireless regulatory-domain behavior. Cisco’s Catalyst 9800 country-code documentation explains that APs use legal frequencies approved for their regulatory domain, and for Japan regulatory-domain devices, Japan country codes must be configured so the controller and APs operate within permitted channel and power constraints. Cisco also states that country codes are assigned and verified on APs or wireless controllers to ensure regulatory compliance for wireless operation. Manufacturing batch inspection, customer onboarding, and supplier-chain evaluation are not RF spectrum regulatory functions.
