HOME  /  Corporate Profile and History

Since Sankei Industry was founded in Ritto, Shiga in September 1960, it has been growing steadily as an aftermarket automotive parts manufacturer (suspension and steering-related parts in particular) and continues to satisfy the demands of customers around the world. With the increase of Japanese auto exports in recent years, our 555 brand products have also experienced export growth, and are currently used as critical safety parts in more than 120 countries around the world, accounting for 98% of Sankei Industry's product supply. In August 1999, Sankei received ISO 9001 certification, an international standard for quality management systems; since then Sankei has been committed to further improving not just quality, but every aspect of our day-to-day operations.
