MASUNAGA 1905

A legacy of craftsmanship, perfected over generations.
Established in 1905, MASUNAGA is one of Japan’s oldest and most revered eyewear houses. Every frame and every step of production is handcrafted in-house — a rarity in the industry — allowing complete control over quality, detail, and finish. The result is eyewear that feels as refined as it looks: harmonious blends of titanium, acetate, and subtle design signatures rooted in Japanese precision.
At SEASONS Optical, MASUNAGA represents quiet excellence — timeless pieces that speak to those who value heritage, mastery, and understated elegance.

MASUNAGA K3 designed by Kenzo Takada is a collaboration between MASUNAGA and Kenzo Takada, world renowned Japanese designer.

Since its launch in 2014 Paris France, the collaboration has created high-quality luxury eyewear through combining vintage inspired elements with fashion forward contemporary design.
