Opt Inc.

A leading Japanese digital marketing agency, now fully integrated into the Hakuhodo DY Holdings group following the merger of Digital Holdings into OPT Inc. in 2026.

OPT Inc. is a Tokyo-based digital advertising and marketing agency operating within the Hakuhodo DY Holdings group. The company provides a broad range of digital marketing services including search engine marketing, social media advertising, programmatic display, content marketing, and data-driven performance advertising for Japanese and international brands. OPT has historically been one of Japan's prominent independent digital marketing specialists, known for its expertise in online advertising operations, analytics, and digital strategy consulting. OPT's corporate structure underwent significant change when Hakuhodo DY Holdings took its former parent, Digital Holdings (previously known as OPT Holding), private in March 2026, after which Digital Holdings merged into OPT Inc. This consolidation brought OPT fully under the Hakuhodo DY Holdings umbrella, integrating it more deeply into one of Japan's largest advertising conglomerates alongside agencies such as Hakuhodo and Daiko. The merger streamlined the group's digital marketing capabilities into a single operating entity. As part of the Hakuhodo DY Holdings network, OPT Inc. is positioned as a core digital agency arm serving a wide range of Japanese advertisers across industries including retail, finance, automotive, and consumer goods. The company competes with other major digital agencies in Japan such as Dentsu Digital and CyberAgent, leveraging its group affiliation and deep expertise in performance-driven digital advertising to serve both large enterprise clients and growing brands seeking measurable online marketing outcomes.
