KIO Yamato’s KT‑564U Hachi frame takes the eight‑facet concept beyond geometry to explore balance, proportion and refined craftsmanship. With a slightly oversized shape and whisper‑light titanium construction, this frame sits at the intersection of art and eyewear. Each facet is softened to create a fluid, sculptural presence on the face while remaining true to KIO Yamato’s philosophy of quiet precision—objects reduced to their purest form, where every detail serves a purpose.

The Meaning of Hachi (KIO Hachi: Eight‑Faceted Design in an Oversized Silhouette)

In Japanese, hachi (八) denotes the number eight—a symbol of openness, balance and harmonious expansion. KIO Hachi builds its identity around eight facets that gently transition from one to the next. This deliberate softening transforms a strict geometric form into a fluid, wearable contour and echoes the brand’s commitment to shaping objects that transcend the ordinary. By choosing a slightly oversized eight‑sided design, the frame carries subtle cultural resonance while speaking to contemporary minimalism. Each facet catches light in a measured way, creating calm radiance and giving the frame its sculptural presence. (KIO Hachi: Eight‑Faceted Design in an Oversized Silhouette)

Design Philosophy: Purity, Proportion and Detail (KIO Hachi: Eight‑Faceted Design in an Oversized Silhouette)

KT‑564U Hachi reflects a refined approach to eyewear: purity of line, precision of shape and balance of proportion. Every piece emerges from a meticulous process where traditional artistry meets precision engineering, resulting in a balance that feels effortless yet is defined by complexity and purpose. On a design level, this means:

Pure lines and precise shapes – The oversized eight‑sided lenses and bridge are reduced to their essential curves, creating movement and lightness. Subtle asymmetry ensures the shape feels natural rather than rigid.
Perfect proportions – The thickness of the titanium rim, height of the bridge and length of the temple arms are tuned so the frame feels balanced on the face. This proportional harmony allows KIO Hachi to stand out without overpowering the wearer.
Fine detailing – Engraving runs along the temple arms and bridge, and the edges of each facet are smoothed for comfort. Each element is meaningful and executed with a discerning eye for materials.
Timelessness through simplicity – The clean geometry and meticulous craft give KT‑564U Hachi longevity beyond trends. It’s designed to become part of your daily rhythm, offering subtle luxury and lasting comfort.

Materials and Craftsmanship

Titanium Construction – The frame is forged from high‑grade titanium for strength, flexibility and lightness. This material choice allows a thin profile even in an oversized shape.
Finishes – KT‑564U Hachi comes in three finishes:
- Rose Gold – warm and luminous, complementing skin tones.
- Paladium – cool and modern, emphasizing precision.
- Brushed Titanium – understated and architectural, highlighting the engraving.
- Japanese Gold – A calm glow that settles naturally on the face.
