Masunaga Sunglasses

Sun of Japan: Proud Retailer of Masunaga Sunglasses

Sun of Japan is honored to present Masunaga, a distinguished Japanese eyewear brand renowned for its exceptional craftsmanship. Since its inception in 1905, Masunaga has evolved into a celebrated manufacturer of premium handmade sunglasses, synonymous with precision and quality.

Masunaga Optical pioneered the eyewear industry in Fukui, Japan, under the leadership of its founder, Gozaemon Masunaga. With the goal of establishing Fukui as a prominent hub for eyewear production, Gozaemon brought together skilled artisans from Osaka and Tokyo, laying the foundation for the brand's enduring success. This strategic move not only fostered a rich heritage of craftsmanship but also positioned Fukui as one of the world's most significant centers for eyewear production. The legacy of this early ambition continues to define the precision and artistry that characterize Masunaga eyewear today.

Crafting each Masunaga frame requires an intricate process involving up to 200 manual steps. Uniquely, Masunaga Optical remains the only company in Japan to oversee every stage of production, from sourcing raw materials to the final finishing touches, ensuring unmatched quality control and precision. By maintaining this integrated production process, Masunaga ensures that every frame meets their exacting standards of craftsmanship.

The manufacturing process includes meticulous polishing techniques that enhance the texture, smoothness, and shine of each frame. Every stage — from molding and forming the frame’s structure to shaping the acetate and applying final touches — is conducted with precision and attention to detail. This process reflects Masunaga’s steadfast commitment to delivering products that not only excel in functionality but also exude elegance and durability.
