Japanese eyewear craftsmanship since 1905

Founded in 1905 in Fukui Japan, MASUNAGA is one of the most respected names in Japanese eyewear craftsmanship. As the first company to establish an integrated eyewear production system in Japan, MASUNAGA has overseen every stage of frame making from design to final assembly for more than a century.

MASUNAGA frames are defined by precision engineering, refined materials, and uncompromising attention to detail. Titanium components are meticulously finished to achieve exceptional durability, balance, and long term comfort. Rather than following trends, the brand focuses on timeless design and structural excellence.
