Overview

A magnificent Japanese Ko-Imari square dish featuring a lobed central medallion containing a stylized dragon, framed by vibrant iron-red (aka-e) scrolling foliage and underglaze cobalt blue geometric borders. The canted rim showcases delicate enamel painting of phoenixes (hōō) and floral reserves.

Story

During Japan's Edo period, Arita artisans perfected the complex process of two-stage firing to create vibrant Imari porcelain. The rich iron-red enamel required a second, lower-temperature kiln trip after the underglaze blue was set. This square dish blends auspicious symbols like dragons and phoenixes into a harmonious, prized serving vessel.

Maker / Origin

Rather than a single artisan, Ko-Imari porcelain was produced by highly specialized guilds of potters, painters, and kiln masters in Arita. The aka-e-ya (overglaze enamel specialists) operated in distinct quarters, carefully guarding their secret formulas for iron-red and polychrome pigments.

Condition & Value

The enamels and gilding appear remarkably well-preserved with crisp color definition and minimal visible wear on the interior display face. As with all early square porcelain, minor firing imperfections or glaze gaps near the rim corners are expected and natural. Excellent overall preservation greatly enhances market appeal.

Value Drivers

  • Strong maker attribution with credible period details
  • Better-than-average condition for the category
  • Broader demand rises when presentation and finish feel intact

Concerns

  • Decorative-only demand limits the ceiling
  • Surface wear or missing provenance can compress the range fast
  • Regional sale lanes often underperform specialist venues
