If you have ever browsed Japanese ceramics, you have probably seen the terms “Arita ware” and “Imari ware” used interchangeably — and then wondered if they’re the same thing. The answer requires a short history lesson, but the short version is: they mostly are the same thing, and the difference is about who named them and when.
The Short Answer
All authentic Arita ware and most Imari ware come from the same region — the town of Arita in Saga Prefecture, Kyushu. The difference is primarily a naming convention with historical roots, not a difference in the pottery itself. In Japan, this porcelain is called Arita-yaki (有田焼). In the Western antiques market, the same ware — especially older export pieces — is called “Imari ware.”
Why “Imari”?
Imari was the port town through which Arita porcelain was shipped for export. Japan’s first porcelain was produced in Arita around 1616, after the Korean potter Ri Sampei discovered high-quality kaolin clay in the area. Within decades, Arita’s kilns were producing white porcelain decorated with cobalt blue — a product Japan had previously imported from China — in sufficient quantity to begin exporting.
The Dutch East India Company (VOC) began importing Japanese porcelain at scale from the 1650s, particularly as Chinese exports were disrupted by the Ming-Qing dynastic transition. The porcelain was loaded onto ships at the port of Imari, the nearest coastal town to the inland kilns of Arita. European buyers therefore called it “Imari ware” after the port of origin — the same way English speakers call sparkling wine “Champagne” after the French region.
This name stuck in the European and American antiques market, where “Imari” still specifically refers to the richly decorated export porcelain of the 17th and 18th centuries: dense patterns in cobalt blue underglaze, iron red overglaze enamel, and gilding. This distinctive palette was so influential that it was copied by Meissen (their “Indian flower” or indianische Blumen pattern), Delft, Worcester, and other European factories through the 18th century.
In Modern Usage
| Term | Where Used | Meaning |
|---|---|---|
| Arita-yaki (有田焼) | Japan | All porcelain from the Arita region, any period |
| Imari ware | Western antiques market | Old Arita export porcelain (17th–18th century) |
| Ko-Imari (古伊万里) | Japan and West | Specifically the Old Imari style — dense blue/red/gold patterns from c.1660–1760 |
| Imari-yaki (伊万里焼) | Japan | Technically, ware produced within Imari city itself — a small subset |
What About “Old Imari”?
Ko-Imari (古伊万里, “Old Imari”) is the term used both in Japan and the Western market to describe the densely decorated export style produced roughly from 1660 to the 1760s. The characteristic visual vocabulary — overlapping patterns of chrysanthemums, phoenixes, and scrolling vines in cobalt blue underglaze with iron red and gold overglaze — was developed partly in response to European taste, which wanted something visually richer than the cleaner Chinese porcelain styles.
Genuine Ko-Imari pieces from the Edo period appear regularly at auction houses in London, New York, and Tokyo. A good example — a large dish or covered jar with clear decoration and minimal restoration — can fetch £2,000–15,000 depending on condition and rarity. The market has also produced generations of later reproductions, particularly Meiji-period (1868–1912) copies that are themselves now antiques and can be confused with the originals by inexperienced buyers.
Buying Tips for Collectors
Read the base mark carefully. Genuine Edo-period Arita porcelain often carries a double-circle mark (fuku mark) or Chinese reign marks copied in a decorative, non-functional way — Japanese potters adopted Chinese mark styles as a design convention, not to claim Chinese origin. 19th and 20th century pieces often have more legible Japanese marks or kiln names. Pieces with no mark at all are common in early Arita work and shouldn’t automatically be dismissed.
Condition matters more than age. In the Ko-Imari market, a well-preserved later piece is often more desirable than an earlier piece with significant repair or hairline cracks. Traditional Japanese repairs using urushi (lacquer) are visible and acceptable; invisible modern repairs require UV light to detect and significantly reduce value. Major auction houses (Christie’s, Sotheby’s, Bonhams, Mainichi Auction) are the safest venues for significant purchases and provide condition reports. For pieces under £500, reputable specialist dealers and vetted online markets provide reasonable access.
Modern Arita ware is available at a wide range of prices and represents excellent value for daily use. The Arita region still produces high-quality domestic porcelain — both traditional patterns and contemporary designs from studios like 1616/Arita Japan, which collaborates with European designers. This is not Ko-Imari, but it is the same living tradition.
