In 1905, Masunaga Optical started producing eyeglasses in Fukui, Japan. Since then, Fukui has become one of the leading optical frame production centers in the world, along with Italy and China. The integrated production system employed by Masunaga allows quality and attention to detail to be maintained throughout the 200 manual processes required in creating a single frame. Masunaga prizes its rich history and meticulous craftsmanship, which is still evident today in its unique handcrafted frames.
