MASANUGA

Glasses of the finest craftsmanship

Masunaga Optical premiered the production of eyeglasses in Fukui 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.

There are 200 manual processes involved in making a single MASUNAGA frame, each of which can take up to 6 months to produce.

Masunaga Optical is the only company in Japan that has an integrated factory in charge of all processes, from raw materials to production and finish. The integrated production system improves the detail and quality. Each frame is hand made, one by one, by skilled craftsmen.

Before the barrel polishing process, MASUNAGA Craftsmen hand file the backside of the frame front and temple edges, which is one of the key steps to provide the best comfort.
