Overview

An impressive 39 cm Japanese Old Imari (Ko-Imari) porcelain bowl decorated in cobalt blue underglaze (sometsuke). It features panelized reserves of floral sprigs and diaper patterns surrounding a central medallion with a flying creature, while the base bears an apocryphal Chinese Chenghua mark typical of Edo-period production.

Story

During Japan's Edo period, potters in Arita crafted magnificent blue-and-white porcelain for wealthy domestic patrons and European trading ships. Artisans frequently painted prestigious 15th-century Chinese Ming reign marks onto the base as a homage to ceramic quality, rather than an intent to deceive.

Maker / Origin

Produced by master potters in the Arita region of Hizen Province, modern-day Saga Prefecture. Arita was the birthland of Japanese porcelain, developing sophisticated kiln firing and underglaze brush techniques in the early 17th century that supplied both the Shogun's court and the Dutch East India Company.

Condition & Value

Displays minor surface kiln pitting, glaze pop flaws, and slight wear along the unglazed footring typical of authentic period wares. No obvious large chips or structural cracks are visible in the photos, though close inspection under UV light is advised.

Market Analysis

Comparable demand stays strongest where maker, originality, and venue confidence line up. Broader examples still trade, but the range tightens quickly when provenance, condition, or selling lane fit is missing.

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
