Company information
Fujiseiko was founded in 1958 with the aspiration of "creating the finest precision tools in Japan (Fujiseiko)," following the German Meister system. Since then, we have contributed to the development of the industrial sector and local communities, albeit modestly, through our manufacturing in the field of precision tools. As a total engineering company that supports all aspects of work related to manufacturing sites to solve our customers' problems, we contribute to the advancement of manufacturing environments. While our main products and services are targeted at customers involved in metal parts processing, in recent years we have expanded our products and services using the technology and know-how we have cultivated for parts used in electrified vehicles (EVs, HEVs). - We propose solutions using our accumulated technology to address the unique needs and challenges of each customer. - We realize advanced manufacturing techniques and high-quality production through the fusion of the latest technology and skilled craftsmanship. - We carefully select and propose the best products from around the world, not limited to our own offerings. - We provide prompt support by being close to our customers' factories around the globe.
