Katayama Manufacturing LLC (KML) provides global automotive manufacturers with Tier 1 manufacturing solutions. We are committed to building professional partnerships based on mutually agreed expectations of Quality, Delivery and Cost.

As a third-generation, family-owned business, we take pride in our role as a trusted Tier 1 supplier to many of the world's leading automakers. The original Katayama facility was founded in 1947 by Kakuji Katayama in Okayama, Japan. Since then the Katayama Group has grown as a private manufacturing entity. Our initial offerings comprised of automotive exhaust flexible tube and other tube-related products. From these modest origins, we have evolved to produce a comprehensive range of Tier 1 automotive interior and exterior parts.

Looking ahead, our enduring legacy of expertise and commitment to continuous enhancement will propel us to establish new standards in product manufacturing.

Our commitment to people and partnerships guides us into the future.

We are driven by the power of connection—bridging continents and cultures to deliver excellence across our products. With three distinct facilities in Japan, the USA, and Mexico, each rooted in its local community, Katayama fosters innovation and collaboration that drives growth and strengthens the regions we serve.

We Are One Company.
