There is a common assumption in eyewear that strength requires mass.

For Fall Winter 2026, KIO YAMATO challenges that assumption with 羽 Hane, the Japanese word for feather.

Hane was not chosen simply as a seasonal theme or visual reference. It represents the central engineering philosophy behind the collection: how light can a frame become without compromising its integrity?

Rather than treating weight as another specification on a product sheet, we approached lightness as part of the architecture of the frame itself.

Every material. Every millimeter. Every structural decision.

Each was reconsidered with one objective: reduce what is unnecessary while preserving what matters.
