Design Philosophy:

The KT-569U distills everything KIO YAMATO stands for — minimal form, ergonomic mastery, and a deep commitment to comfort. With a sleek clubmaster-inspired silhouette and fine details in proportion and flow, this frame is both timeless and forward-thinking. It’s an ideal choice for those who seek lightness in both weight and design.

Technical Features:

• Ju-Shi Hinge Technology
  Engineered with KIO’s Ju-Shi hinge system, the KT-569U ensures lasting durability and silky motion. Using dual resin washers to stabilize movement and reduce wear over time, it prevents temples from loosening and maintains a snug, dependable fit.

• 1.0mm Ultra-Slim Beta Titanium Temples
  This frame represents the lightest range within the Ju-Shi series, featuring ultra-fine 1.0mm beta titanium temples. Designed to naturally contour the head, they offer:

  • A weightless feel for all-day wear

  • Adaptive ergonomic fit

  • Barely-there pressure on ears and temples

  • Resilience and flexibility that maintains its shape

• Japanese Titanium Construction
  The upper browline and eye rims are made from precision-cut Japanese titanium — offering a balanced structure with minimal bulk.

Why Choose the KT-569U:

• Featherweight Functionality
  Designed with our slimmest temple architecture, the KT-569U is so light you may forget you’re wearing it. It’s the frame that disappears on your face — but leaves a lasting impression.

• Engineered to Move With You
  Thanks to the Ju-Shi hinge and beta titanium temples, this frame flexes where it needs to while keeping structure where it counts. Whether you’re sitting, walking, or constantly shifting — it adjusts in real time.

• Sleek, Modern Elegance
  The softly squared silhouette paired with the half-rim design makes it both expressive and subtle. It’s equally at home in formal and creative environments.

• Handcrafted Excellence
  Made in Japan by expert artisans, every detail — from the hinge action to the metalwork — is a result of rigorous craftsmanship and decades of optical innovation.

Ideal For:

• Professionals seeking discreet, ergonomic eyewear

• Those who prioritize ultra-lightweight design

• Fans of subtle clubmaster silhouettes

• Long-term wearers who demand lasting comfort and structure
