Dentsu Inc. (株式会社電通 Kabushiki-gaisha Dentsū?) is an international advertising and public relations company whose headquarters are located in the Dentsu Building in the Shiodome district of Minato, Tokyo.[2] It is the parent company of Dentsu Aegis Network.


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.[citation needed]

In 1995, Dentsu created five domestic regional subsidiaries.[citation needed]

Dentsu was listed on the Tokyo Stock Exchange in 2001. During the initial public offering of Dentsu, in December 2001, a trader at UBS Warburg, the Swiss investment bank, sent an order to sell 610,000 shares in this company at ¥1 each, while he intended to sell 1 share at ¥610,000. The bank lost £71 million.[3]

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.[citation needed]

On 12 July 2012 Dentsu agreed to acquire British-based Aegis Group plc in a cash deal worth $4.9 billion. The deal was completed in March 2013.[4] Dentsu announced that it would launch Dentsu Aegis Network, which would manage all Aegis Media work and non-Japanese Dentsu operations worldwide.[5]


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 to help develop Facebook pages, Facebook ads, and marketing strategies in general.[citation needed] The partnership also provides Dentsu with premium advertising space on Facebook.


Dentsu has two operations in India, Dentsu India and Dentsu Aegis Media.[6]

With 48 floors that rise to 213.34 m (700 ft), it is the eleventh-tallest building in Tokyo. It was designed by Jean Nouvel, the French architect, and completed in 2002. It was built over the site of Tokyo's first train station, and sits aside the Hamarikyu Gardens, formerly the site of a Shogun's vacation home.

Mt Fuji Climbing Tradition[edit]

Since 1925 Dentsu employees has had a company tradition of climbing Mount Fuji.[7] Every July all new staff and newly promoted executives climb Mt Fuji. Employees who are not physically able to do so are exempt. A former employee gave the reasoning behind this as: "The message is: 'We are going to conquer the one symbol that represents Japan more than anything else. And, once we do that, it will signify that we can do anything.'"[8]
