Regulation on the use of signal jammers in Japan


Japan is an East Asian country known for its thriving economy and technological leadership in various fields. However, like in many countries, the use of signal jammers is a growing concern for Japanese authorities due to risks to public safety and violations of intellectual property rights.

Laws and Regulations

In Japan, the use of signal jammers is strictly regulated by law. Under Japan's Radiocommunications Law, it is prohibited to produce, import, sell, or use signal jammers without prior government authorization. Signal jammers are only permitted in specific situations, such as military operations, laboratory testing, or research and development activities.

Effective Date

The Radiocommunications Law was enacted in 1950 and has been regularly updated since then to reflect the latest technological advancements. Regulations regarding signal jammers were added in 2015 to better protect wireless communications from disruptions.

Regulatory Bodies

In Japan, the use of signal jammers is regulated by the Ministry of Internal Affairs and Communications (MIC) and the National Institute of Information and Communications Technology (NICT). These organizations are responsible for monitoring the use of signal jammers in the country and ensuring that rules and regulations are followed.

Legal Authorization

To obtain authorization to use a signal jammer in Japan, one must submit an application to the MIC or NICT, providing a detailed justification for the intended use of the signal jammer and proving that its use is necessary for security or research reasons. Applicants must also demonstrate their ability to use the signal jammer without causing harm to the communications of other users.
