Meaning
A mandatory certification emblem applied to radio equipment to show compliance with the Japanese Radio Law and Telecommunications Business Act. The mic japan giteki mark indicates that a wireless device has been certified by a registered conformity assessment body for use on Japanese frequencies. This symbol must be displayed on all radio-transmitting hardware before it can be legally imported, sold, or operated in Japan.
Technical Conformity
Verification of the device requires testing for frequency tolerance, occupied bandwidth, spurious emissions, and antenna power. A developer obtains the right to display the mic japan giteki mark after submitting these test results alongside schematics and firmware descriptions to an approved registrar. Japan regulates its spectrum strictly to prevent interference with local communication networks, making this certification essential for any connected device.
The resulting registration number must be search-accessible on the official ministry website.
Labeling Requirement
The conformity mark must be printed on the product housing or displayed electronically on a screen if the device has a built-in display. This label must meet specific size and legibility requirements defined by Japanese law. Incorrectly sized or placed marks can lead to import rejection at the border.
Enforcement Mechanism
Selling radio equipment without this mark can result in severe financial penalties and product recalls. This strict enforcement protects the integrity of the public radio spectrum from non-compliant transmitters.
