Dentsu
Dentsu Inc., stylized as Dentsu, is a global advertising and public relations powerhouse headquartered in Tokyo, Japan. As the largest advertising agency in Japan and the fifth largest worldwide by revenue, Dentsu holds a pivotal role in global media and advertising landscapes.
The company commands an impressive 28 percent of Japan's national advertising budget, maintaining deep-rooted connections with nearly every major Japanese institution. These extensive ties include such closeness to the national government that The New York Times has described Dentsu as "the unofficial communications department of the governing Liberal Democratic Party." This influence is so significant that comparisons have been drawn between Dentsu and the CIA, highlighting its expansive reach and power within corporate and political arenas.
