Experience and achievements in air intake parts for trucks.

We are a manufacturer of metal parts established in 1951. Our main products are truck parts. We have experience in manufacturing intake manifolds and other air intake parts, axle bearing retainers and other undercarriage parts, and also radiator side tanks and other cooling parts. Our customers include UD Trucks, Kubota, and Isuzu Motors. Our company was established as a cooperative factory for the former Nissan Diesel Motors. Since then, we have accumulated considerable knowledge and experience in designing and manufacturing processing jigs and in small-lot production of aluminum-cast products by machining. We will actively participate in exhibitions and business fairs to extend our sales channels.
