Fukui, Japan is one of the three largest production regions for optical frames in the world, along with China and Italy.
Masunaga 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 as many as 200 manual processes involved in making an optical frame. Generally, productivity is low when one company is in charge of all the processes.
However, Masunaga Optical is the only company in Japan that has a factory in charge of all processes from raw materials to production and finish in an integrated way. The integrated production system improves the detail and quality. For example, when Masunaga Optical develops a new model, the moulds are always built in-house.
