Dentsu is the largest advertising conglomerate firm in Japan (controlling over 30% of the total market by revenue and an estimated 40%-50% of commercial airtime on Japanese television) and one of the largest advertising conglomerates in the world. It operates in 27 countries. 95% of revenue currently comes from Japan.

Like Havas, it began as a news service and advertising agency. In line with Japanese and major overseas competitors the group's services include media and event planning, market research and public relations. It also has large-scale printing, data processing and systems integration, music publishing, exhibition, film and other operations.

It has alliances with WPP (eg a partnership with US-based Young & Rubicam) and a stake of around 15% in Publicis.
