Dentsu Inc. (株式会社電通 Kabushiki-gaisha Dentsū ) is a Japanese advertising and public relations company whose headquarters are located in the Dentsu Building in the Shiodome district of Minato, Tokyo.
Dentsu's sales are more than double its nearest competitor, Hakuhodo or ADK, in the Japanese market, thanks to the company's origins as a media representative during the early part of the 20th century, producing the first newspaper advertisements as well as the first television commercials in Japan. The company now offers a range of services, from traditional and creative marketing to specialty disciplines such as sports marketing, investing in feature film production and acquiring broadcasting rights, PR, digital contents, and a growing range of communications services.
Dentsu was originally established as Japan Advertising Ltd. and Telegraphic Service Co. by Hoshiro Mitsunaga. In 1906, Telegraphic Service Co. became Japan Telegraphic Communication Co., Ltd. The next year, Japan Advertising Ltd. merged with Japan Telegraphic Communication Co., Ltd. to create advertising and communications operations.
In 1936, Japan Telegraphic Communication Co., Ltd. sold off its news division to Doumei News Agency, to change the company's focus to specialized advertising. In 1946, 16 companies were acquired in order to supplement Japan Telegraphic's advertising business. That same year, operational bases were established in Tokyo, Osaka, Nagoya, and Kyūshū.
In 1951, with the arrival of commercial radio broadcasting in Japan, the Radio Division is established at Japan Telegraphic's head and local offices.
In 1955, Japan Telegraphic Communication Co., Ltd. changed its name to Dentsu.
In 1995, Dentsu created five domestic regional subsidiaries.
Dentsu became part of the Tokyo Stock Exchange in 2001.
Dentsu categorises project markets in four different parts: National advertisement market; Advertisement related market; New market; Foreign market. National advertisement market consists of media projects. Advertisement related projects consist of marketing services. New market consists of sport events advertisement. Foreign market contains above mentioned three categories in the foreign market.

In March 2011, Dentsu formed an official partnership with Facebook Inc. to help develop Facebook pages, Facebook ads, and marketing strategies in general. The partnership also provides Dentsu with premium advertising space on Facebook.
