JIAA

Japan's leading interactive advertising trade body and the official IAB licensee (IAB Japan), setting standards and guidelines for the country's digital advertising ecosystem.

The Japan Interactive Advertising Association (JIAA) is the primary trade body for the interactive advertising industry in Japan, founded in 2000. With a membership of more than 300 companies spanning publishers, agencies, ad technology providers, and media platforms, JIAA serves as the central standards-setting and advocacy organization for digital advertising in Japan. Since January 2017, it has operated as IAB Japan, the official licensee of the Interactive Advertising Bureau (IAB), aligning Japan's digital advertising ecosystem with global frameworks and best practices. JIAA's core activities include issuing advertising guidelines, ethics codes, and technical standards that govern how digital advertising is bought, sold, and measured in Japan. The association conducts an annual user-trust survey to monitor consumer attitudes toward online advertising, and it plays a key role in educating the industry on privacy, data usage, and responsible advertising practices. These initiatives help member companies navigate regulatory developments and maintain public trust in digital media. As IAB Japan, the association bridges the Japanese market with the global IAB network, enabling local adoption of international standards such as those related to programmatic advertising, viewability, and brand safety. JIAA holds a unique and authoritative position in Japan's advertising and media landscape, functioning as the industry's self-regulatory body and a key interlocutor with government and regulatory stakeholders.
