What DK Holdings does

DK Holdings (株式会社DKホールディングス) is a privately held Osaka-based holding company founded in 1965 by Yoshino Michihiro as a sign-making business and reorganized into a three-subsidiary structure in June 2017. The group operates a vertically integrated spatial design and event production business that delivers end-to-end event space creation — from creative concept through in-house fabrication to on-site installation — primarily to advertising agencies (notably Dentsu) and corporate brand clients in Japan.

The group's core operating subsidiaries are 第一広房OSAKA and 第一広房TOKYO (event and display design plus in-house production studios for woodworking and sign making), DKマーケティング (venue coordination, the 職人BASE matching platform, and franchise operations), and TASUKI (architectural and spatial design, established April 2024). Production infrastructure centers on the 江戸スタジオ in Kawaguchi, Saitama — a 3,370-tsubo integrated base housing a 930-tsubo woodworking studio, a 400-tsubo sign studio, and logistics/distribution functions — equipped with Zünd G3 CNC cutters, ANAPURNA large-format printers, and EPSON SC-S80650 printers. The January 2025 absorption merger with MIK (ミッケ) added 35 nationwide logistics bases and a 1,000+ vehicle fleet for event equipment transportation and storage.

Revenue is generated through professional services fees for event space design and installation (project-based, one-time), transaction-based equipment and venue rental, managed services for event hall coordination, subscription revenue from the 職人BASE platform (¥50,000/month for unlimited matching), and franchise operations of FIT-EASY amusement fitness clubs (2 stores), Dohtonbori okonomiyaki restaurants (2 stores), and 222 discount outlet stores (3 stores). The company serves enterprise clients including Toyota, Epson, Hakuba, Shueisha, Grand Front Osaka, and the Expo 2025 Osaka organizers, and holds ISO9001, ISO45001, and Privacy Mark certifications.
