Creating the future. In pursuit of infinite possibilities.

Starting in 1934 with the development and production of biological microscopes, we have continued manufacturing primarily OEM products for a variety of precision optical instruments tailored to customer needs—including medical microscopes—since becoming independent from our predecessor, Chiyoda Kogaku Kogyo, in 1976.

Drawing on our extensive experience as a long-established manufacturer, we respond to customer needs with the optical, mechanical, and manufacturing technologies we have cultivated over many years.
