Overview

This monumental Japanese porcelain basin (ōhachi), measuring approximately 36 cm in diameter, features expressive underglaze cobalt blue (*sometsuke*) painting of birds among flowering camellia and pine branches. Complete with its fitted period wooden storage box (*tomobako* or *jidaibako*), it exemplifies the bold, functional domestic wares produced in the Hizen kilns.

Story

Fired in the historic climbing kilns of Arita, this monumental 36 cm basin survived centuries of banquets. Its historic repairs reflect the Japanese philosophy of cherishing and preserving treasured family heirlooms.

Maker / Origin

Produced by skilled artisans in the ceramic center of Arita in Hizen Province (modern Saga Prefecture). During the Edo period, these communal climbing kilns supplied both elite domestic households and foreign export markets with durable, high-fired porcelain.

Condition & Value

Multiple extensive through-body hairline cracks and consolidated rim fractures with old repairs and localized staining/crazing. The accompanying wooden box shows authentic age-related patina and light surface wear. Historic damage and repairs reduce commercial value by roughly 50–70% compared to intact examples.

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
