Hakuhodo DY ONE

Japan's largest dedicated digital marketing agency, formed as the digital core of Hakuhodo DY Holdings and a co-leader of the H+ APAC regional network

Hakuhodo DY ONE was established on April 1, 2024, through the strategic merger of D.A.Consortium (DAC) and IREP, two of Japan's most prominent digital marketing firms. Created as the designated digital-marketing core under Hakuhodo DY Holdings' FY2024 medium-term plan, the company consolidates deep expertise in programmatic buying, performance marketing, paid search, and data-driven campaign management under a single, unified brand. With approximately 3,200 employees based primarily in Tokyo, Hakuhodo DY ONE represents one of the largest dedicated digital marketing operations in Japan. The company serves as a full-service digital marketing partner for major Japanese and multinational advertisers, offering an integrated suite of capabilities spanning media planning and buying, search engine marketing, social advertising, programmatic display, and advanced audience data solutions. Its scale and technical depth allow it to operate proprietary ad technology platforms alongside partnerships with global DSPs, SSPs, and data providers, giving clients access to both local market expertise and international programmatic infrastructure. Hakuhodo DY ONE co-leads the H+ APAC network alongside Hakuhodo Inc., extending its digital marketing capabilities across the Asia-Pacific region. Its formation reflects a broader industry trend of consolidating specialist digital agencies into integrated powerhouses capable of competing with global holding company networks. The company occupies a dominant position in Japan's digital advertising market, leveraging the combined heritage, client relationships, and technology assets of its predecessor companies to deliver measurable outcomes for enterprise advertisers.
