What Sango does

Sango Co., Ltd. (株式会社三五) is a Japanese Tier 1 automotive parts manufacturer headquartered in Miyoshi City, Aichi Prefecture, with operations spanning Japan, the Americas, Europe, and Asia. The company manufactures exhaust systems (catalytic converters, exhaust manifolds, mufflers, and heat recovery systems), body and chassis press components, drivetrain parts (differential shafts, propeller shafts, reduction gears, and ITCC shafts), and precision steel products (polished bars, mechanical structural pipes, piston pins, and turbine shafts). Its manufacturing capability is built on six proprietary process technologies: pipe plastic forming, sheet metal stamping, joining, bar material processing, wire material processing, and measurement and assembly, all developed over a history tracing to the founding of the Toyota Technical Center in 1963 and predecessor activity dating to 1928.

The company operates a vertically integrated B2B model covering planning, development, design, production, and supply, with direct long-term supply contracts and just-in-time delivery to automotive OEMs. Sango maintains 14 domestic production and support facilities across Aichi, Mie, Hokkaido, Ibaraki, and Fukuoka prefectures, and eight wholly-owned overseas subsidiaries in the United States, Canada, Mexico, Turkey, Thailand, Indonesia, India, and China, with an R&D center in Guangzhou. Notable technology assets include heat recovery exchangers for hybrid vehicles, novel pipe-bending dies recognized by the Japan Plastic Processing Society, and exhaust systems validated in motorsport (Lexus LC at the Nürburgring 24 Hours).

Sango generates revenue primarily through negotiated B2B hardware sales to automotive OEMs; pricing is not publicly disclosed. The company has diversified beyond core automotive into JIS-certified medical and face masks, the FP35 next-generation piping system for construction (jointly developed with Shin Nippon Air Conditioning), and sustainability products such as WOOD BOTTLE. Recent recognition includes the 2026 Japan Logistics Award (with Mujin Japan) for warehouse automation, the 2025 Ministry of Land, Infrastructure, Transport and Tourism Green Infrastructure Grand Award for the ECO35 facility, ISO 14001 certification across all major sites, and ISO 9001:2015 certification across domestic operations.
