CEO Minoru Yanagisawa／Born in 1983
ABOUT US
Based on what we have accumulated so far,
we are becoming a company that continues to “evolve”!
Since our company was founded in 1985, we have mainly manufactured jigs and tools (polishing plates) that serve as standards for the curvature of optical lenses.
In April 2011, we were able to successfully change the CEO, and we have now been in the business for over 30 years. Currently, customer requests are increasing, and in addition to plates, we also provide lens holders and other tools. We will not only focus on quality more than ever before, but we also want to be a company that continues to evolve. We do this by being sensitive to changes of the times, trends in the industry, and new technologies.
