One step forward! A challenge towards an unlimited future! Our top priority is to create products that satisfy our users.

Daiwa Koki Co., Ltd. has long been highly regarded for its technology as a cooperative factory in the automotive press and sheet metal division of Toyota Body Co., Ltd. Since 1961, through the research and development of the former president, a bending processing method for H-shaped steel used in tunnel construction was devised, leading to the birth and commercialization of H-shaped steel supports. Subsequently, this processing technology was recognized by the industry, and with the development of the business, in January 1963, the machinery division of Daiwa Koki Co., Ltd. was separated, and a new corporate organization named Daiwa Koki Co., Ltd. was established. It became a certified processing factory for H-shaped steel supports by Kawasaki Steel Corporation, enhancing its equipment and technology. Additionally, in 1982, in response to the needs of the tunnel industry, it began manufacturing steel centering, achieving numerous accomplishments and receiving positive feedback. Our motto is to deliver better products to users more quickly and at lower costs.
