Chord Series

The Masunaga Chord Series is inspired by the harmony and progression of guitar chords—from Chord A through Chord G. Just as each chord creates its own tone and character, every frame in the collection carries a unique balance of style, precision, and artistry.

Handcrafted in Fukui, Japan, each piece takes nearly six months to complete, passing through over 200 meticulous steps performed by 150 skilled artisans. With refined detailing and timeless design, the Chord Series captures the rhythm of craftsmanship—eyewear that resonates with individuality, harmony, and elegance.
