Mutsumi Kogyo

What Mutsumi Kogyo does

Mutsumi Kogyo (睦工業株式会社) is a privately held Japanese contract manufacturer founded in January 1960 in Numazu, Shizuoka Prefecture, with 210 employees (as of January 2017) and five manufacturing locations across Japan and China. The company operates an integrated production model spanning design, press processing, welding, assembly, inspection, wiring, programming, on-site installation, and after-sales service, with capabilities including 22 presses (25-200t), 15 spot welding machines, 16 ultrasonic welders, 8 hot caulking machines, and 78 automated assembly and inspection systems.

Its core business is the manufacture of automotive and motorcycle lighting equipment — headlamps, tail lamps, license plate lamps, and high-mount stop lamps — as well as precision press metal parts such as lens holders, shades, strength plates, and mounting rings. The company's largest disclosed customer relationship is with Koito Seisakusho (株式会社小糸製作所), a major global Tier-1 automotive lighting supplier, with whom it has worked since November 1991 (press parts) and March 1992 (assembly).

Mutsumi generates revenue primarily through B2B direct sales of custom-manufactured hardware, with pricing determined through consultation based on customer specifications, budget, and delivery schedule rather than published tiers. It also derives revenue from custom automatic assembly equipment and inspection jigs sold to industrial customers. Distribution is direct-to-OEM with no intermediaries; the Guangzhou factory serves as a manufacturing hub for global supply chain customers. The company is led by President and Representative Director Shinya Suzuki, holds ISO 9001 certification (since 1999, updated to JIS Q 9001:2015), and has received METI designations including Regional Future Leading Enterprise and the 2017 Omotenashi Standard Certification.
