Japan Sales Promotion

What Japan Sales Promotion does

Japan Sales Promotion (株式会社ジェイエスピー / JSP) is a Tokyo-based sign construction and advertising company founded in September 1971 and incorporated in November 1978 with ¥50 million in registered capital. Operating from Adachi-ku, Tokyo, JSP delivers integrated signage solutions under its "Totalsign" (トータルサイン) approach — spanning planning, design, fabrication, installation, and maintenance for indoor and outdoor signs including neon signs, monument signs, rooftop billboards, wall signs, pict signs, and CI/corporate identity signage, as well as solar power equipment installation for logistics and commercial facilities. The firm is led by Representative Director Daichi Shibuya (渋谷 大一) and maintains a small, highly experienced craft workforce (~20 employees, average 21-year tenure).

The company's business model combines project-based sign construction services with owned billboard media rentals. Construction revenue is generated through direct enterprise sales to major Japanese general contractors — most prominently 大成建設, 鹿島建設, and 竹中工務店 — plus corporate end-clients including みずほ銀行, 城北信用金庫, ヒューリック, 東京建物, 髙島屋, and others across banking, real estate, retail, hospitality, healthcare, and education sectors. Billboard media revenue is generated through two owned packages: J-Board (50-face station-area set priced at ¥10M per 4-week campaign) and Capital Board (30-face urban set priced at ¥6M per 4-week campaign), plus individual large-format rooftop and wall-mounted billboard rentals at prime Tokyo locations.

JSP holds comprehensive regulatory credentials that anchor its competitive position, including a Class 1 Architect Office registration, Outdoor Advertising Registration, and a multi-specialty Construction Business License covering 15+ trades (specialty electrical work, painting, waterproofing, steel structure, glazing, interior finishing, and others). Project execution spans the Tokyo Metropolitan Area plus major Japanese cities including Osaka, Sapporo, Yokohama, Kawasaki, and Saitama, with a steady project throughput of roughly 20+ sign construction completions per year from 2020 through 2025, complemented by solar equipment installations for logistics facilities.

Direct peers

• Nomura Co., Ltd. (乃村工藝社): Japan's largest pure-play signage and commercial-environment design company, offering planning, fabrication, and installation for retail, hospitality, and corporate clients — directly comparable to JSP's Totalsign service. Operates at significantly larger scale than JSP but serves the same core customer base (developers, contractors, retailers) with overlapping sign-installation capabilities.
• Tanseisha Co., Ltd. (丹青社): Major Japanese signage and spatial-design firm with end-to-end sign and display production for commercial facilities, offices, and public spaces. Highly comparable to JSP in service mix (planning through installation) and target segments including retail, hospitality, and corporate clients across Japan.
• Rackland Co., Ltd. (ラックランド): Mid-sized Japanese signage construction company specializing in end-to-end sign manufacturing and installation for commercial facilities, retail chains, and real estate developers. Closely comparable business model to JSP — design, fabrication, and installation of signs for enterprise clients — with a similar focus on construction-company partnerships.

Broad incumbents

• Dai Nippon Printing Co., Ltd. (DNP): One of Japan's largest printing conglomerates, with a significant signage and interior-decoration production business serving retail, commercial, and public-sector clients. Provides overlapping capabilities to JSP in sign manufacturing and installation but operates at vastly larger scale and across diverse end-markets.
• Toppan Holdings Inc. Diversified Japanese printing and information-communications conglomerate with a substantial sign and spatial-solutions segment producing signage, displays, and interior environmental graphics. Competes with JSP on larger enterprise sign projects but as part of a much broader printing/media portfolio rather than as a sign specialist.
• Hakuhodo DY Holdings: Japan's second-largest advertising agency group, providing full-service advertising, media buying, and creative services including outdoor advertising planning. While not a sign fabricator, Hakuhodo frequently plans OOH campaigns (the demand side of JSP's billboard inventory) and works with sign execution partners on enterprise-level campaigns.

Regional players

• NKB Inc. (株式会社NKB): Japanese advertising, signage, and digital-display company that has partnered with JSP on projects including Haneda Airport Terminal 1 digital signage and rooftop signs. Operates in the same Tokyo-based sign and OOH market as JSP with overlapping enterprise client relationships, making it a directly relevant regional peer.
• Showa Denki Co., Ltd. (昭和電工 / Showa Denki Group): Japanese electrical construction and sign-installation firm serving similar commercial and industrial customers in Japan, including solar and electrical infrastructure work comparable to JSP's diversification into solar equipment installation. Comparable mid-sized competitor in the same domestic Japanese market.

Others

• Dentsu Inc. Japan's largest advertising agency and global media company, planning OOH campaigns that consume billboard inventory similar to JSP's. Acts as a media buyer and campaign planner that often directs clients to OOH suppliers, positioning Dentsu as adjacent ecosystem participant rather than direct manufacturing competitor.

Emerging players

• LIVEBOARD Inc. Japanese digital out-of-home (DOOH) advertising network operating connected digital billboards across train stations and urban areas, including partnerships with construction/real-estate firms. Targets the same advertiser demand pool as JSP's static J-Board/Capital Board packages but delivers it via digital, programmatic channels — directly competitive for ad spend allocation.
