Masunaga Optical was founded in 1905 by Gozaemon Masunaga and was the driving force behind the development of the optical industry in Fukui, Japan.
The birth of the MASUNAGA since 1905 collection pays tribute to classic and timeless designs of Masunaga’s own historic frames.
In September 1933, Masunaga Optical presented three solid gold frames to the Emperor of Japan when he visited Fukui area.
The MASUNAGA G.M.S. (Gozaemon Masunaga Spectacles) series is directly inspired by the frames created for the Emperor.
In 1970 one of our products, the “Custom 72”, was placed in the time capsule at the Osaka World Expo. This remarkable result of the Custom 72 has inspired the designs of the MASUNAGA collection.
Meticulous craftsmanship is evident in the countless steps of the manufacturing procedures. Masunaga does not rush the process. No shortcuts are taken; no compromises are made in the creation of each MASUNAGA frame.

Featuring beautifully hand polished Japanese acetate, high grade pure Titanium, durable seven barrel hinges, distinctive silver rivets, MASUNAGA since 1905 collection confirms what Masunaga Optical has achieved over the past century.

For the 2019 F/W collection, MASUNAGA introduces 12 new ophthalmic styles and 3 sunglass models including the new MASUNAGA Chord line.
MASUNAGA Chord features super thin 0.7mm front rim, 0.9mm thick original temple design and comes in two versions: Ti and Ti + K18 version. Chord Ti uses Gum Titanium, a highly elastic titanium alloy, featuring double elasticity with respect to B titanium.

Chord Ti + K18 version is fashioned from the world first welding technology using B titanium and solid 18 Karat Gold. The Chord Ti + K18 version is perfectly balanced, keeping the most of the weight of solid gold at the temple end. MASUNAGA Chord is a harmony of elegant designs and techniques cultivated over 100 years.
AMARYLLIS is the new cat eye sunglasses from MASUNAGA designed by Kenzo Takada collection. It features newly designed temples created with a motif from a lorgnette handle that was popular in the 19th century. The double rim front design with spaces at the bridge and the upper rim is inspired by the Japanese aesthetics of space.
