Conclusion

Glass has become a regular part of everyday Japanese life, but this was not always the case. The craftsmanship of glass only set foot into Japan in the 17th century, alongside western medicine. After its introduction into the islands, glass has taken its own, uniquely Japanese path in the form of "Kiriko" (cut glass), a traditional Japanese form of glass-crafting.
One of those kiriko glass crafts is "Edo Kiriko", a traditional craft of Tokyo that has come to lead the Japanese aesthetic to the world. We will explore the history behind its production and patterns, as well as other glass crafts in the Taisho/Showa eras. You might just find some great inspiration for gifts, or pieces of glassware to incorporate into your everyday life!

History of Japanese Glass Craftsmanship: its Roots in the Edo Era

Nowadays, glass is used commonly as a part of our everyday life. The history of today’s Japanese glassware is rather young, and was actually introduced to Japan in the Edo era (1603 - 1868). Though the exact dates are unknown, it is said that glass was first imported into Japan in the tools of western medicine during this time period.
It is not until much later in the Meiji era, that glass-manufacturing techniques were imported into Japan too, allowing glass tableware to be commonplace the way it is today.

Despite this relatively late entry of Japan into glass craftsmanship, there are a wide variety of traditional glasswares in Japan. Among its most famous is definitely the "Kiriko-zaiku", a type of glassware characterized by vivid colors, broken up by intricate patterns cut into the glass. High-quality Kiriko glasswares made in Tokyo are specifically called "Edo Kiriko", and captivate the hearts of many with their colorings and cut patterns.

How did Edo Kiriko come to be, and how did it develop? We asked Hirota Glass co., ltd, a glass-manufacturing company in the Sumida Ward of Tokyo.

Edo Kiriko, a Renown Handicraft of Tokyo

How did Edo Kiriko come to be in the first place?
We had an interview with Mr. Tatsuro Hirota, COO of Hirota Glass co., ltd.


Mr. Tatsuro Hirota, COO of Hirota Glass co., ltd.

Mr. Hirota tells us:
"The origins of Edo Kiriko are said to trace back to the works of the Edo period glass merchant, Kagaya Kyube. Like today's Edo Kiriko, he applied cuts to imported glass products. That being said, it was quite recent that this began to be referred to as 'Edo Kiriko'."
It seems that things resembling today's Edo Kiriko have been in production for a long time, but they were only given their current name recently.

The word “Kiriko” is considered to have been created in the Meiji era, since it appears in an episode of Rosanjin Kitaoji, a Japanese artist who was popular from the Meiji to Showa period.

On the other hand, Tokyo-made Kiriko glassware only came to be called "Edo Kiriko" within the past 100 years. The craftsmanship of Edo Kiriko was always inherited by the efforts of late-Edo townspeople, but it was the Meiji-era contribution of English glass-cutting technicians that gave Edo Kiriko the vibrance and intricacy that it has today.

How Edo Kiriko Glassware is made: A delicate process of glass-cutting


Exclusive Tokyo SkyTree-patterned Edo Kiriko glassware
There is a wide range of Edo Kiriko in a variety of colors stocked in Sumida Edo Kiriko-kan. You can always find over 350 Edo Kiriko on display. The classic red Edo Kiriko is of course in stock, alongside the deep blue variants. The pigments of red and blue are created respectively by copper and cobalt, and apparently it is quite difficult to color a glass surface in red!

It never gets old, taking in the artistry and deep craftsmanship that goes into the shimmering, light-refracting surfaces of Edo Kiriko glasswares. It seems most common to buy them as gifts for special occasions, but they might also make great luxurious companions to your relaxed, everyday dinner table.

Despite the narrow grooves covering the surfaces of Edo Kiriko, maintenance is quite easy. They can be cleaned with dish soap like any other glass, and just by occasionally cleaning out the grooves with a cotton swab, your Edo Kiriko can be kept beautiful for a long, long time!

Today, we were given the special opportunity to have a look at process of the craftsmen actually making Edo Kiriko.


Rough-grinding process. Concentration and technique is essential to curve beautiful patterns.

This is the initial process called Ara-kezuri(rough-grinding), in which patterns are cut into the glass. To create the patterns, colored glass is placed on top of clear glass, and ground away to reveal the base layer.
This thin layer of colored glass makes Edo Kiriko unique. The slightest cut will reveal the clear glass underneath, so creating a beautiful pattern is an extremely intricate process that requires huge amounts of experience and technique.


Curving elevates finer from inking and indexing, rough-curving, Second-kake to Third-kake. Glass turns into transparent by Stone-kake.

Mr. Kozo Kawai, an Edo Kiriko craftsman and meister of Sumida Edo Kiriko-kan, was doing the cutting today. He is a highly-skilled craftsman with about 30 years of Edo Kiriko-making experience, who says that it takes over 10 years and a huge amount of dedication to master the process and become a competent craftsman. Stable hands and adequate pressure are embedded into the muscle memory over years of practice.

He told us about how difficult it is to acquire the technique. He says:
“In my initial years, it was very hard for me to adjust my pressure and make a straight cut. Whether you can master the technique depends on whether or not you can endure in the initial 2 or 3 years.”.

What are the Common Patterns of Edo Kiriko?

Edo Kiriko come in a variety of beautiful colors including blue, red, purple, green and pink, but their intricate patterns are worth just as much praise. The typical kiriko glassware adopts a geometric pattern, but Edo Kiriko takes much of its inspiration from the delicate kimono designs of Edo.

Glassware made with care, to speak to your nostalgia

Although glassware is used so regularly in our everyday lives, we rarely think about the procedures in which they are made. Take any two pieces of glassware, and the two will have been crafted using different technologies and techniques.

One example is the “arare” series with the pattern of raised dots, characterized by soft hues of pink or yellow. In their crafting, heated glass is poured into a mold and pressed into shape. They carry a refreshing look, which is perfect for plating sweets with.


"Setsu-getsu-ka" (Snow, Moon and Flower) Arare series (from ¥1,100)

The old-fashioned glassware is also made with press technique, and has a look reminiscent of retro cafes. These are part of the "Fukkoku" (classic reproduction) series, and includes plates, tumblers, and more.


Fukkoku series (from ¥880)

The tumblers are characterized by thick bottoms, which Mr. Hirota tells us is a result of catering towards the cafes and restaurants using them to serve drinks. The thick bottom allows the establishment to fill it to the brim with less liquid, and the light refraction at the bottom gives the illusion of a more full glass.


Thick-bottom tumblers were often used in cafes in the Showa era

This series is sure to bring back memories for Japanese people who remember the Showa era. It includes many relatively affordable pieces within the ¥1000 range, and make great pieces for serving guests with.

The "Taisho Romantic Glass" catches your eye with soft opal-colored patterns

Pay special attention to “Taisho Romantic glass”, which makes use of the "aburidashi" technique that was common in the Tiasho era. The foggy white patterns are not applied via paint, but exposed by blowing molten glass into unevenly shaped pattern molds.


Taisho Romantic glass (from ¥2,750)

The pale white color is created by using calcium extracted from sources such as bone ash, and create a variety of geometric patterns that resemble Edo-era kimono designs. Their beautiful designs make quite the gift.
