Dentsu is the latest agency to enter Myanmar, opening its own branch office of Dentsu Asia this week in Yangon.
In September, Coca-Cola made headlines by returning to Myanmar after an absence of more than 60 years, becoming one of the first multinational consumer marketers in the country of close to 60 million people.
The new Dentsu office will work mainly with the network's Japanese clients, Dentsu said.
"A new foreign investment law was enacted in November 2012, and the eagerness of foreign companies to enter the Myanmar market is growing rapidly," Dentsu said in a statement. "Several Japanese companies have already started to develop a market presence in Myanmar, and Western and local companies are also showing an increase in activities there."
Dentsu also noted that the Southeast Asian Games, involving 11 countries in the region and multiple sports, will be held this year in Myanmar, fueling demand for sports sponsorship and related advertising. Sports events and sponsorship are one of Dentsu's strengths.
The branch manager of the new Yangon office will be Hardy Yang, currently a director of Dentsu Asia.
