Yazaki’s timeline of success dates back to 1929 when Sadami YAZAKI began selling wiring harnesses for automobiles. As a truly global company deeply rooted in Japanese cultural traditions and values, YAZAKI strives to be a reliable partner to its customers as well as a promoter of environmental sustainability throughout the world. We are especially proud to be the world's largest producer of wiring harnesses and at the same time offering environmental systems, with emphasis on energy-related equipment.
