Company Overview

HOME  >  Company Overview

Our goal is to promote our customers’ success by providing automated machines which incorporate all the latest
“mechanical, computer, service and network” technologies!


ITAYA is the brand leader in the production of spring making machinery. Our company specializes in providing machine equipment to produce springs.

In 1947 Reijiro Itaya, the founder of our company, established ITAYA in the Tateishi, Katsushika area of Tokyo. Since then we have consistently developed, designed and manufactured automated production machines.

These machines included, amongst others, automated assembly machines for ladder chains and roller chains, automated production machines for heat-dissipating corrugated fins for radiators, automated assembly machines for safety pins and mechanical pencils, etc.

From the early 1970s our research and development have focused on the rapidly advancing electronic control technology for automated machinery and we succeeded in developing the world's first “microcomputer-controlled spring forming machine” in 1977. Since then we have been developing, designing and manufacturing machines specific to spring making.

We have three intrinsic values:

These are “Our goal is our customers’ success”, “Always keep on developing” and “Our employees are our treasure”.

We have always honored our commitment to our customers and to the continuation of research and development for the advancement of the company, understanding that the company will decline if this development ceases. We also place huge importance on valuing the relationship with our employees in the spirit of friendship.

I can proudly declare my trust that our company will continue its efforts with ongoing research and connecting with customers and employees in order to become the top in our industry.
