Thank you very much for visiting the home page of DIA SEIKI SEISAKUSHO Co.
In this renewal, we have created a home page that can be used comfortably from smartphones and tablets as well as PCs.
It used to be a PC-only home page, but in consideration of the times, it now supports mobile devices such as smartphones.
We will strive to make this site even easier for you to use, and we look forward to working with you in the future.
