Dentsu

• 1. Foundations And Early Growth

  ›

  In 1906, the company known as Dentsu began its life under a different name. Telegraphic Service Co. transformed into Japan Advertising Ltd. The next year, Japan Advertising Ltd. merged with Japan Telegraphic Communication Co., Ltd. to create advertising and communications operations. This merger established the core business that would eventually become the largest agency in Japan. In 1936, Japan Telegraphic Communication Co., Ltd. sold off its news division to Doumei News Agency. This sale shifted the company's focus entirely toward specialized advertising services. By 1943, the firm had acquired sixteen other companies to supplement its growing advertising business. Operational bases were then established in Tokyo, Osaka, Nagoya, and Kyūshū. When commercial radio broadcasting arrived in Japan in 1951, the Radio Division was created at the headquarters and local offices. In 1955, Japan Telegraphic Communication Co., Ltd. officially changed its name to Dentsu Inc.

  ›

  Dentsu moved beyond Japanese borders through significant international acquisitions. On the 12th of July 2012, the company agreed to acquire British-based Aegis Group plc in a cash deal worth $4.9 billion. The deal completed in March 2013. Dentsu Aegis Network managed all Aegis Media work and non-Japanese Dentsu operations worldwide. In September 2020, Dentsu Group Inc. announced that its international business would operate under the dentsu brand. This simplification established three lines of business across media, customer relationship management, and creative. The business is registered as Dentsu International Limited with UK Companies House in October 2020. Earlier efforts included acquiring Pioneer LDC from Pioneer Corporation in July 2003. They renamed it Geneon Entertainment while renaming its North American division to Geneon USA. On the 12th of November 2008, Dentsu sold 80.1% of its ownership in Geneon to NBCUniversal's Universal Pictures International Entertainment. The merger closed on the 1st of February 2009. In 2018, Dentsu acquired GlobalMind, a LATAM based digital first agency based out of Argentina and Miami, USA.

• 3. Corporate Structure Evolution

  ›

  On the 10th of December 2018, Dentsu announced its intention to restructure into a holding company. Changes took effect by the 1st of January 2020. Most functions including advertising moved to a new company under the Dentsu name. The existing company rebranded to the Dentsu Group name. Dentsu was listed on the Tokyo Stock Exchange in 2001. During the initial public offering in December 2001, a trader at UBS Warburg sent an order to sell 610,000 shares at ¥6 each. He intended to sell 16 shares at ¥600,000. The bank lost £71 million due to this error. The Dentsu Building is a high-rise structure in Shiodome, Minato, Tokyo. It houses corporate offices with 48 floors rising to 213.34 meters. Jean Nouvel designed the building which completed in 2002. Since 1925, employees have maintained a tradition of climbing Mount Fuji. Every July all new staff and newly promoted executives climb Mt Fuji. Employees who are not physically able to do so are exempt.

  In April 2015, Dentsu announced the launch of a corporate venture capital fund named Dentsu Ventures. This initiative provided companies across the U.S., Europe, and Asia with capital and business support. In the same month, Dentsu Ventures Global Fund I launched with a total capital of five billion yen. In May 2021, Dentsu Ventures Global Fund II launched with a total capital of ten billion yen.

Dentsu Inc. categorizes project markets into four parts: National advertisement market, Advertisement-related market, New market, and Foreign market.

• 5. The Karoshi Tragedy

  ›

  In August 2015, Dentsu exceeded its own 70-hour monthly maximum overtime limit. Matsuri Takahashi, a University of Tokyo graduate and 24-year-old female employee, committed suicide in December. The Japanese government recognized her death as karoshi, meaning death from overworking. In July 2017, authorities charged the company for Takahashi's death. No individuals were charged, only the corporation. The company admitted allowing illegal levels of overtime and was convicted in October. They paid ¥500,000 in fines. Mr. Tadashi Ishii notified Dentsu on the 28th of December 2016 that he would resign as Representative Director and President & CEO. His papers went to prosecutors due to violation of the Labor Standards Act. Over half a century of ongoing overworking was documented by The New York Times. Training materials supported a Dentsu president urging workers to work even if it kills you. A 2017 attempt to encourage leaving the office at 3 p.m. on the last Friday of the month did not get much participation. In 2017, a former executive creative director resigned following allegations of sexual harassment.

• 6. Olympic Scandals And Politics

  ›

  In 2022, a former executive at Dentsu was arrested on suspicion of receiving bribes from sponsors of the 2020 Summer Olympics. In February 2023, Japan's competition regulator filed criminal complaints against six firms including Dentsu. They faced alleged bid rigging of contracts for the games. Companies were charged under anti-monopoly law and accused of lowering competitiveness of their tenders. The case saw arrest of a senior Olympic official from Japan and head of Dentsu's sports division. The company admitted liability. Corruption scandals clouded chances of landing the 2030 Winter Olympics by Sapporo. One media report stated Dentsu does business with almost every major institution in Japan. It accounts for about 28 percent of the national advertising budget. Connections to government are so tight that The New York Times referred to Dentsu as the unofficial communications department of the governing Liberal Democratic Party. Dentsu played a major role during Roki Sasaki's MLB team selection process resulting in his signing with Dodgers in 2025.
