Tokio, la capital de Japón, es también un centro de artesanía. Entre ellas, el vidrio Edo y el Edo Kiriko son piezas de cristalería japonesa tradicional que se han transmitido de generación en generación durante unos 200 años en la ciudad de Edo, el antiguo nombre de la zona central de Tokio.

Estos artículos de vidrio maravillosamente brillantes han sido refinados en la ciudad de consumo más grande de Japón, continuando la buena y antigua tradición japonesa hasta la era moderna.

About Edo Glass

Edo Glass is a handmade craft that carries on techniques passed down since the Edo period. Unlike mass-produced items, each piece is one-of-a-kind, shaped with subtle variations and warmth that only handcrafted work can offer. These pieces are made by skilled artisans in areas around Tokyo, and their quiet beauty has earned them popularity both in Japan and abroad. In 2014, Edo Glass was officially recognized as a Traditional Craft by Japan’s Ministry of Economy, Trade and Industry.

History of Edo Glass

Glass first arrived in Japan through Portuguese and Dutch imports during the Sengoku period (1467–1600 CE). Blown glass production began in Edo around 1711, and by the 18th century, glassware like wind chimes, kanzashi, and sake cups had become part of everyday life. In 1879, Tokyo saw the rise of Western-style glass factories, but many workshops were later lost to major disasters in the 20th century. Even so, the craft endured—and today’s Edo Glass carries on that legacy, piece by handcrafted piece.

Edo Kiriko

About Edo Kiriko

Edo Kiriko is a traditional craft where intricate engravings are made on the surface of Edo Glass. Around twenty geometric patterns are carved with remarkable precision, creating a jewel-like brilliance as they catch the light. Especially in pieces made with colored glass, the contrast between the vibrant surface and clear glass creates a sharp, striking effect. These refined cuts are made without detailed sketches—only simple guidelines are drawn directly onto the glass, a method unique to Edo Kiriko. Edo Kiriko was officially designated a Traditional Craft by Japan’s Ministry of Economy, Trade and Industry in 2002.

History of Edo Kiriko

Edo Kiriko began in 1834, when a glass merchant named Kagaya Kyubey first etched glass with garnet stone powder. The technique matured in the Meiji era, when English glass artisan Emanuel Hauptmann introduced Western methods. Eventually, a signature style emerged: deep cuts on colored glass layered over clear glass. From the Taisho period (1912-–1926 CE) onward, Edo Kiriko grew into a beloved decorative art—one that still flourishes in Tokyo today.

Crafting of Edo Kiriko

Waridashi/Sumi-tsuke

In the production of Edo Kiriko, no detailed sketches are drawn for the design. Instead, a process called waridashi (dividing) or sumi-tsuke (inking) is used to mark the layout directly on the glass. These marks are then followed by lightly carving thin, shallow lines with a whetstone wheel to serve as the foundation for the final pattern. From these faint lines alone, the intricate motifs of Edo Kiriko are brought to life.

Arazuri – Sanbangake

For Edo Kiriko engraving, artisans use kongo-sha, a coarse garnet powder, along with rotating metal wheels. In the initial stage called arazuri, the design is carved roughly using the coarsest grain. This is followed by sanbangake, which uses finer abrasives to refine the lines. Although no rough sketch is drawn, the thickness and depth of each cut are achieved with remarkable precision, guided solely by the craftsman’s skill and sense of balance.

Ishikake

In the final carving stage called ishikake, patterns from earlier steps are refined using a whetstone disk. This process smooths the engraved surface and allows for intricate details that can’t be achieved with metal wheels. As the final cutting step, ishikake plays a key role in determining the clarity and finish of the piece. The work must be done with great care to avoid leaving behind any coarse marks.

Migaki

After ishikake, the surface of the glass appears cloudy, like frosted glass. The polishing stage, called migaki, restores transparency and brings out Edo Kiriko’s signature shine. Using water and polishing powder, artisans polish the piece with wooden disks made of paulownia or willow, as well as bristle or belt disks tailored to the design. Finally, a cloth buffing wheel—known as a habuban—is used to create a glossy, refined finish.
