Masunaga was founded in Fukui, Japan in 1905. The company founder Gozaemon Masunaga brought in skilled craftsmen from Osaka and Tokyo with the ambition of setting the optical industry solidly in place in Fukui.

Masunaga Optical is the only company in Japan that has a factory in charge of all processes from raw materials from production to finishing in an integrated way. The integrated production system improves the detail and quality.

For example, when Masunaga Optical develops a new model, the molds are always built in-house. If there is a problem in the wear comfort that can be felt only after completing one pair of glasses, it will be corrected in the previous process’ promptly.

The company’s mission is We manufacture excellent eyeglasses. We want to make a profit if we can, but we don’t hesitate to take a loss. It is always in our thoughts to manufacture excellent eyeglasses.”
