Message from the representative director

Hiroyasu Komatsu

Hiroyasu Komatsu

Since our founding in 1938, we have been mainly designing and manufacturing construction and agricultural machines in addition to molds for secondary concrete products. Furthermore, we have made great efforts in the development and commercialization of our products, such as concrete pole crushers and hydroponic gardening equipment for home use. In recent years, we have been working in new fields such as aircraft ground support equipment, medical care, the environment and renewable energy as well as commencing the development of a “step elimination machine” in cooperation with West Japan Railway Company.

Our company embraces the idea that “A company is its people.” While change and innovation are required, we raise added value by improving each staff’s skills and planning the advancement of our consistent production system and strengthening our design development ability in order to provide products and service that satisfy our customers.

We will continue growing ourselves in line with our customers’ developments, and try to be a company that contributes to solving social issues. Your support and encouragement are deeply appreciated.
