Our late founder, Masao Inagaki, founded ASATSU (Asahi Tsushin-sha) in 1956 with only 4 employees. This small advertising agency with a challenger spirit grew rapidly to become the third largest agency in Japan. And in 1999, the merger with Daiichi Kikaku formed ASATSU-DK (ADK).

Starting January 2019, ADK will transform into a holding company structure with ADK Holdings Inc. (ADKHD) as a pure holding company. ADK will become a collective group of business entities in which each operating company will strengthen professional areas and increase productivity, optimising the output we can offer.
