Global marketing and communications network Dentsu is celebrating its 125th anniversary, marking a milestone that reflects more than a century of transformation from a Japanese news agency into one of the world’s largest marketing and advertising groups.

The anniversary was commemorated by Dentsu President and Global CEO, Takeshi Sano, who described the occasion as an opportunity not only to celebrate but also to reflect on the relationships, partnerships and trust that have shaped the company’s journey.

Founded in 1901 by Hoshio Mitsunaga, Dentsu began as a news agency in Japan built on the belief that communication could connect people, businesses and society. Over the decades, the company expanded beyond its roots to become a global marketing, advertising and communications powerhouse with approximately 67,000 employees operating across around 120 markets worldwide.

Today, dentsu ranks among the world’s largest marketing services groups, providing integrated capabilities across media, creative, customer experience management and technology.

Reflecting on the milestone, Sano noted that no company reaches such longevity alone, attributing Dentsu’s success to the trust of clients, the commitment of employees and the support of partners across generations.

“Our story has been shaped by the trust of our clients, the partnership of so many organizations, the dedication of our people, and the relationships we have built across generations,” he said.

Sano said the company’s evolution over the past 125 years has been driven by a culture of curiosity, creativity and innovation, qualities that continue to define its approach as the marketing industry undergoes rapid technological and consumer shifts.

Despite dramatic changes in media, technology and consumer behaviour, he noted that Dentsu’s core mission has remained unchanged: helping clients grow while creating lasting value for society.

“As we look to the future, our focus remains the same – to put our clients first and continue to innovate in ways that create meaningful outcomes for our clients, our people and society,” Sano said.

The anniversary comes at a time when the marketing and communications industry is being reshaped by artificial intelligence, data-driven decision-making, evolving consumer expectations and increasing demand for integrated customer experiences.

For Dentsu, the milestone serves as both a celebration of its legacy and a reminder of the need to continually adapt in an increasingly complex business environment.

Looking ahead, Sano expressed confidence that the same spirit that guided the company’s first century will help it remain relevant for future generations.

“The first 125 years were only possible because of our clients, partners, colleagues and friends around the world,” he said. “We have inherited an extraordinary legacy, and I look forward to everything we will continue to create together in the years ahead.”

As Dentsu enters its next chapter, the company says it remains committed to innovation, collaboration and client growth principles that have defined its journey since 1901 and continue to shape its future in the global marketing landscape.
