Free Shipping: On all orders over $50
Named Kochō, the Japanese word for “butterfly,” this Edo Kiriko hand-cut crystal whiskey glass combines fine geometric detail with sweeping, wing-like facets.
Radiating cuts extend across the clear crystal like an opening pair of wings, surrounded by intricate traditional Edo Kiriko patterns that break light into smaller, shifting reflections. The fully transparent design keeps the craftsmanship visible from every angle, allowing the depth and precision of the cutting to become the focus.
As the glass turns in the hand, broad facets and densely carved sections reflect light at different intensities, creating a layered sense of movement without relying on color. The result is a clear crystal whiskey glass that feels intricate, sculptural, and distinctly Japanese in its approach to pattern and light.
Designed for whiskey and aged spirits, Kochō can also be displayed as a decorative piece where the hand-cut structure can be fully appreciated.

Mastery Carved into Every Facet
Edo Kiriko preserves a 190-year Tokyo legacy, where master artisans hand-cut Japanese crystal whiskey glasses through a rigorous six-step process. Using traditional grit wheels instead of industrial molds, we transform raw crystal into sharp, light-refracting prisms that define authentic craftsmanship.
The Breath of Life - Blowing
Molten glass is heated to over 1500°C and hand-blown into form. For colored pieces, multiple layers are fused together and annealed for more than 16 hours to ensure strength and stability.
The Blueprint - Marking
Reference lines are drawn by hand, creating a grid that guides every future cut.
The First Cut - Rough Carving
Guided by years of intuition rather than machines, the artisan uses a coarse diamond wheel to carve the initial bold patterns. This stage requires immense physical strength and a steady hand to define the soul of the design.
Refining the Spirit - Fine Carving
Switching to finer grinding wheels and natural whetstones, the craftsman meticulously refines every line. This stage transforms raw cuts into delicate, light-refracting textures.
Precision Detailing - Detailing
The final intricate motifs are hand-carved with microscopic precision. This is where the artisan’s true skill shines—creating a mesmerizing play of light that defines authentic Edo Kiriko.
The Final Glow - Hand-Polishing
Instead of chemical dipping, we use traditional rubber and cloth wheels with specialized polishing compounds. This labor-intensive manual polish preserves the sharp edges of the carvings while bestowing the glass with its signature brilliant luster.
Each JR piece is uniquely hand-blown and sculpted. Subtle ripples, tiny bubbles, or pattern variations are not flaws—they are the "fingerprints" of the master craftsman, authenticating a truly handmade work of art.
