What 株式会社シグナル does
株式会社シグナル (Signal Co., LTD) is a privately held sign design, production, and installation company headquartered at Nagahisa-cho, Oda City, Shimane Prefecture, Japan. Founded in April 1935 as Sugimoto Kougeisha, reorganized as a limited liability company in February 1988, and renamed to its current corporate form in September 2006, the firm has operated continuously for over 80 years. It runs a single integrated business offering design-through-installation services for a broad portfolio of physical signage products — outdoor LED illuminated signs, neon signs, advertising towers, road signs, reinforced glass signs, flex-face LED signs, and LED backlit box letter signs — plus complementary construction services including building and bridge painting, coating waterproofing, pavement section line work, large-format tent and canvas structures, car wrapping, holiday illumination, and graphic/logo design. A dedicated maintenance, inspection, renovation, and repair service targets aging outdoor signage. Underlying technology is conventional sign manufacturing with LED illumination as the primary modern differentiator; no software platform, app, or API is offered.
The company serves enterprise, retail, healthcare, education, and government clients — explicitly named verticals include drugstore chains, home center stores, hospitals, schools and welfare facilities, and the public sector — primarily across Shimane Prefecture, with outdoor advertising permits held in 10 western-Japan prefectures (Shimane, Tottori, Hiroshima, Okayama, Yamaguchi, Hyogo, Kyoto, Wakayama, Mie, Nara). Revenue is generated through custom project-based contracts for one-time signage manufacture, professional installation labor, and ongoing maintenance/repair work; no public pricing is disclosed. Distribution is direct: inquiry-form and phone-based field sales from the Oda City headquarters and an Izumo City sales office, with no third-party channels, resellers, or online commerce.
The firm employs 17 staff, an unusually credentialed roster for its size: 1 second-class architect, 3 first-class civil engineering managers, 1 second-class building construction manager, 2 outdoor advertising specialists, 2 first-class steel structure assembly skilled workers, first-class skilled workers in advertising art, architectural painting, and waterproofing, 2 second-class electrical construction engineers, plus a special electrical worker and hazardous materials handling license. Management is led by Representative Director and President Yamazaki Koji (山﨑 耕二) and Chairman Tanimoto Takaomi (谷本 隆臣). The company is wholly independent with no disclosed parent, investors, subsidiaries, or M&A activity.
