In September 1932, Tokyo Kogaku Kikai Kabushikikaisha (Tokyo Optical Co., Ltd.) was established with the aim of domestically producing surveying instruments upon request from the Army Ministry, based on the surveying instruments division of K. Hattori & Co., Ltd.
In 1989, the company name was changed to Topcon Corporation. We have established a solid position as a comprehensive precision optical equipment manufacturer with a focus on optomechatronic surveying instruments and ophthalmic medical devices .
Since the 1990s, through overseas M&As and alliances, we have expanded our business into new fields such as automatic control technology for construction machinery, precision GNSS, and IT agriculture.
We are working to solve the societal challenges in healthcare, agriculture and infrastructure by DX solution, which makes full use of loT and network technology based on the proprietary technology cultivated since our establishment.

Founded in 1932 A pioneer in optical equipment made in Japan

In 1932, Tokyo Kogaku Kikai Kabushikikaisha (Tokyo Optical Co., Ltd.) was established based on the surveying instruments division of K. Hattori & Co., Ltd.

Initially, the company produced surveying instruments, binoculars and cameras, as well as sniper scopes used mainly by the Army.
After the war, the company focused on manufacturing binoculars and exported them mainly to the United States. In addition, the company produced surveying instruments and contributed to the nation’s postwar reconstruction and development.
In 1947, the company started Ophthalmic and Medical Instruments business. In 1950, the company started manufacturing and sales of type-I refractometer upon request from Eyeglass Wholesalers’ Association who wanted “Made in Japan” refractometer. In the mid-1950s, company’s sales and profit expanded on the back of increasing demands for cameras in Japan. In 1963, the company launched the world’s first single-lens reflex camera with a TTL full-aperture metering system. The camera also received high praise from overseas market.
