ARIB

ARIB, the Association of Radio Industries and Businesses, is a Japanese nonprofit standards organization that develops and maintains voluntary technical standards for radio communication and broadcasting equipment and services. Members come from Japan’s broadcasting, telecommunications, and electronics industries, and ARIB functions as a national forum for consensus-driven standardization. Its standards, often referred to as the ARIB STD series, are widely used in Japan to inform product development, regulatory compliance, and market access. The organization operates under the supervision of Japan’s Ministry of Internal Affairs and Communications and maintains close relationships with international bodies such as the International Telecommunication Union.

ARIB’s activities include developing, revising, and disseminating technical specifications for radio frequency devices, digital broadcasting, and related technologies. It also administers testing and certification programs to verify that equipment complies with its standards, issuing conformance marks for certified products. ARIB’s standards have been central to Japan’s ISDB digital broadcasting system, including ISDB-T for terrestrial television and related services, as well as components for satellite and mobile reception.

Beyond broadcasting, ARIB contributes to standards for mobile communications, radio equipment, and emerging technologies, maintaining liaison with regulators and international standards forums to harmonize specifications where possible. Through its standards and certification processes, ARIB aims to promote interoperability, safety, and innovation within Japan’s radio and broadcasting sectors.
