About TOPIA
TOPIA CO., LTD. is a development service provider and prototyping manufacturer for metal and composite components, founded in 1973 by Eigo Sasaki in Suzuka (Mie Prefecture, Japan). The company produces sheet-metal forming prototypes and assemblies, tools and dies, assembly and inspection fixtures, small-series parts, and carbon composite components. Its processes include press forming and hot stamping, 3D laser cutting, large-scale machining, welding and bonding, as well as body-in-white assembly (White Body Assembly). In addition, TOPIA offers automotive design, engineering and simulation as part of Concurrent Engineering. Its core market is the automotive industry (94% of revenue in 2024); the company also serves aerospace, electronics and mechanical engineering customers and works directly with domestic and international automotive manufacturers. With 1,418 employees (consolidated, as of 2025) and consolidated revenue of 29.2 billion JPY (fiscal year 2025/03), the group maintains locations in Japan and in seven foreign countries, including the German subsidiary EU-TOPIA GmbH (headquartered in Frankfurt am Main, sales office in Stuttgart).
