Masunaga Optical was the first company to produce spectacles in Fukai, Japan in 1905. Fukai is now one of the three largest production regions for optical frames in the world, along with Italy and China. 

As well as this, Masunaga Optical is the only company in Japan that has a factory that is responsible for all manufacturing processes, from raw materials, through production to the finished frame. This integrated production system means Masunaga Optical is renowned for its impeccable detail and quality. 

MASUNAGA collection features beautifully hand polished Japanese acetate, durable seven barrel hinges and distinctive silver rivets, in keeping with the reputation of total quality that Masunaga Optical has achieved over the past century.
