Greetings
In order to respond promptly to changing and diversifying needs,
we continue to take on the challenge of developing new technologies and businesses.

Since our founding in September 1937, we have been devoted to glass processing,
and currently our main business is ultra-precision polishing of photomask substrates for LCDs and automotive mirrors.
We are confident that our ultra-precision polishing technology will satisfy all our customers.
Our company’s history began with simple glass cutting processing,
and as the technology required by the times has changed,
we have expanded the scope of our work to include bending, strengthening, coating, precision polishing, and extra-large precision polishing,
and we have striven to accumulate and improve our technology.
Furthermore, we are committed to the relentless pursuit of high quality and the preservation of the green global environment, with the aim of “building a company that is trusted and satisfied by our customers.”
To achieve this, we obtained ISO9001 certification in April 2003 and ISO14001 certification in February 2004.
We will do our utmost to meet the ever-changing and diversifying needs of our customers,
and will continue to strive to develop new technologies in order to achieve customer satisfaction.
We appreciate your continued patronage and look forward to doing business with you in the future.
President and CEO
Nobuyuki Shinada
