Ko-Imari style is one of the three major styles of Arita ware. It is known for its lavish combination of cobalt-blue underglaze designs, colorful Akae overglaze painting, and brilliant gold decoration. Dense compositions, auspicious motifs, and striking contrasts of red, blue, and gold are its hallmarks. This article focuses on Ko-Imari as a decorative style carried forward in contemporary Arita ware.

What Is Ko-Imari Style?

Ko-Imari is one of the best-known decorative styles in contemporary Arita ware. The three major styles are Ko-Imari, Kakiemon, and Nabeshima.

Of the three, Ko-Imari is especially ornate. On a white porcelain base, cobalt-blue underglaze painting, vivid Akae enamels, and gold accents come together to cover the surface with elaborate designs.

The Difference Between Ko-Imari and Ko-Imari Style

The terms “Ko-Imari” and “Ko-Imari style” are often confused.

As an antique category, Ko-Imari generally refers to porcelain made in Arita during the Edo period and shipped through the port of Imari. Ko-Imari style, by contrast, describes a decorative tradition that carries the elaborate designs of Edo-period Imari porcelain into the present.

Therefore, the word “Ko-Imari” in a modern product name does not necessarily indicate an Edo-period antique. It often describes contemporary Arita ware made in Ko-Imari style.

This article discusses the Ko-Imari decorative style found in modern Arita ware, rather than antique Ko-Imari porcelain.

The Historical Origins of Ko-Imari Style

The roots of Ko-Imari style lie in the flourishing culture of the Edo period. During the Genroku era in particular, prosperous merchant culture and the tastes of feudal lords encouraged demand for luxurious tableware, helping richly colored porcelain with Akae enamels and gilding to develop.

Ko-Imari's appeal goes beyond visual extravagance. Blue-and-white painting, colorful enamels, gold decoration, and auspicious motifs work in harmony to create pieces suited to celebrations and formal settings.

1. Cobalt-Blue Underglaze Painting

Cobalt-blue underglaze painting, known as Sometsuke, provides an important visual anchor in Ko-Imari designs. The blue lends depth and balance to the vivid colors of Akae and the brilliance of gold.

2. Vivid Akae Overglaze Colors

Akae is central to the brilliance of Ko-Imari style. Bright overglaze enamels, often emphasizing red, give the porcelain a festive and lively appearance.

4. Auspicious Motifs

Ko-Imari designs frequently incorporate symbols of good fortune, including peonies, chrysanthemums, birds, phoenixes, scrolling vines, and collections of treasures. Such motifs express wishes for prosperity, longevity, and happiness.

The motifs vary from piece to piece, but their combination with rich colors helps create Ko-Imari's celebratory character.

5. Elaborate All-Over Compositions
