What Ad Arch does
Ad Arch Co., Ltd. (Ad Arch株式会社) is a Tokyo-headquartered, privately held advertising agency group founded in January 2016 by Representative Director Hiroki Shirakawa. The company delivers integrated advertising services across three tightly coupled stages—advertising planning and strategy, media planning, and creative production—under a single provider, with the explicit goal of eliminating the fragmentation clients typically encounter across strategy, media buying, and creative vendors. Its media-mix capability covers Connected TV advertising (TVer), cinema, out-of-home (taxi, hotels, leisure facilities), and digital signage (stations, commercial facilities, educational institutions), with delivery-area design for regional-to-nationwide campaigns.
The firm's defining structural asset is a nationwide network of 26 affiliated group offices spanning 21 prefectures, enabling local client service, on-ground production management, regional shoots, and multi-location projects while maintaining Tokyo-headquarters quality standards. Creative capability is rooted in filmmaking expertise, and the firm reports 500+ completed productions spanning TV commercials, corporate films, sports content, and international/global projects. Customer logos span international organizations (WHO), Japanese government agencies (Ministry of Foreign Affairs, JETRO, JICA), national corporates (NTT, Rakuten, TV Tokyo, Mitsukoshi Isetan, GORE-TEX, JTB, Unicharm), and cultural/sports institutions (National Bunraku Theatre, Renofa Yamaguchi FC).
Ad Arch operates a sales-led, quote-based professional services model with no publicly disclosed pricing. The go-to-market is direct enterprise field sales through the Tokyo headquarters for national accounts and through the 26 regional offices for local clients, supported by a website contact form and phone inquiry system with a two-business-day response commitment. There is no disclosed investor backing, parent company, or M&A activity; the firm is independent and founder-led. Reported HQ headcount is 1-10, with the broader 26-office footprint operating as an affiliated group rather than a fully vertically owned branch network. Revenue is not publicly disclosed.
