A Legacy Since 1905
Masunaga Optical was founded in 1905 by Gozaemon Masunaga in Fukui, Japan—the city that later became
known as the “eyewear capital of the world.” As one of the oldest eyewear manufacturers in Japan, Masunaga
is deeply rooted in tradition and precision.
Full In-House Production
Unlike many other brands, Masunaga controls the entire production process in-house—from mold making
and parts manufacturing to polishing and assembly. This ensures uncompromising quality at every step. The
brand’s motto says it all: “We do not release any frame unless it is perfect.”
Quiet Luxury and Timeless Design
Masunaga eyewear is known for its understated elegance, often blending titanium’s modern appeal with subtle
vintage details. It represents the Japanese spirit of craftsmanship: meticulous, patient, and uncompromising.
For those who value comfort, durability, and discreet luxury, Masunaga is an unparalleled choice.
