Japan has more than one cut-glass tradition. Edo Kiriko grew in the city now called Tokyo. Satsuma Kiriko grew in the Satsuma domain, now Kagoshima. Readers meet both names and want the difference in color, cut, and history.
The short contrast is this. Edo work is often described as a finer, sharper cut on a thinner color layer. Satsuma work is known for a thicker overlay and a shaded cut, a gradation called bokashi. One began as town glass. The other began as a domain industry.
EDO 1834 teaches both as public history. We sell Japanese cut glass. We do not sell either designation on a listing.
Two places, two ways of cutting
Edo Kiriko is dated to 1834 and to Kagaya Kyubei in Odenmacho. It is a city craft. It lived beside other merchant trades and was meant for cups and dishes a household could use. Over the Meiji and Taisho years it absorbed Western cutting instruction and, later, some overlay thinking from the south. Tokyo designated it a traditional craft in 1985. The nation did so in 2002. The story is continuous enough that workshops in Koto, Edogawa, and Sumida still work under that name when they meet the rules.
Satsuma Kiriko is younger as a named project and shorter as a first life. In the 1840s the Satsuma domain, under Shimazu Nariakira, promoted glass as an industry. Domain craftsmen learned to make colored overlay glass and to cut it deeply. The work was shown as a regional achievement, closer to a court and factory object than to a Nihonbashi shop cup. Production lasted only a few decades. War, the death of Nariakira, and the upheavals of the Meiji Restoration closed the first workshops. For about a century the craft was treated as lost. A revival began in the 1980s in Kagoshima, reading old fragments and photographs.
When Satsuma work stopped, some people and some techniques moved. Craft histories say unemployed glass workers and the idea of color-coated glass traveled toward Edo. Edo Kiriko, which had begun on simpler surfaces, took on richer overlay. The two traditions touched. They did not become one name. A glass can show a family resemblance, a deep color opened by a cut, and still belong to only one legal craft, or to neither.
Geography is not romance. Edo is a humid eastern city with a merchant grid. Satsuma is a southern domain that faced the East China Sea and ran its own industrial experiments. The glasses look different because the patrons and the glass blanks were different. A reader who keeps the map in mind will not confuse a Tokyo designation with a Kagoshima revival.
Overlay, depth, and the shaded line
Overlay, or irokise, is a colored skin on a clear body. Both traditions use it. The difference is thickness and what the cutter does with that thickness.
In the usual Edo description the color layer is thin. The cut is relatively shallow and sharp. When the color is opened, the line is crisp. The field reads as geometry: a grid, a star, a petal, a hemp pattern. Light returns as a set of hard highlights. The drink stays easy to see. Everyday use is part of the ideal. A sake cup or a rocks glass should be held, washed, and put back.
In the usual Satsuma description the color layer is thick. The cutter can go deeper and stop at different depths. Because more color remains in some places and less in others, the wall shows a gradation, bokashi, from dense hue to pale to clear. The edge of a cut can look soft, as if the color were dissolving. The object often feels heavier. The picture is less a line drawing and more a shaded print.
Neither description is a ranking. Sharp is not better than shaded. Thin is not more honest than thick. They are two answers to the same material fact: a colored layer can be opened. Edo opened it like a drawing. Satsuma opened it like a wash. A modern table can want either effect, or a cousin of either effect, without needing the legal name.
If you want the method without the proper nouns, read Overlay Glass and the Color Line. The color line is what you can verify with your eye. Designation is what a workshop and a government file verify. Those are different kinds of truth.
- Edo: thinner color, sharper line, town use, continuous craft name.
- Satsuma: thicker color, shaded depth, domain origin, a long pause, then revival.
- Both: overlay on clear glass, cut as the way color is opened.
What the contrast offers a modern table
You do not have to collect designations to choose a glass. You have to decide how you want color to meet the drink. If you want a bright, readable cut and a wall that stays light in the hand, look for a thinner color and a sharp facet field. If you want a deep hue that fades as the cut goes in, look for a thicker wall and a softer step between colors. Those are visual tests. They work in a shop photograph if the picture is honest.
EDO 1834 is a contemporary house. Our catalog is Japanese cut glass, split by use: whiskey glasses, tumblers, sake glasses. Series rooms such as Night Water or First Pour are editorial, not prefecture titles. A Ruby Night Water whiskey glass on a pale table will show you a color line and a pour. It will not make the object Satsuma or Edo. We will not print those names on the card.
History still helps. It tells you why two Japanese words exist, why one craft had a gap, and why overlay looks different from piece to piece. It keeps a buyer from treating kiriko as a single mood. Kiriko means a cut. The place name in front of it matters when the claim is official. When the claim is a shop category, the honest phrase is Japanese cut glass.
