Overview

This is an extraordinary Japanese porcelain rectangular vessel with an overhead handle, decorated in underglaze blue and polychrome enamels featuring herons among weeping willows and water plants. The underside bears the underglaze blue four-character inscription '正保四年造' (Made in the 4th year of Shōho, corresponding to 1647).

Story

The bottom mark references 1647, the era when Japanese porcelain art was first flourishing after kaolin clay was discovered in Arita. Japanese potters frequently inscribed revered historical dates on later Edo and Meiji masterworks as an homage. This distinctive rectangular form was specifically designed for serving sake or fine tea in traditional low-table scholar settings.

Maker / Origin

Arita porcelain began in the early 17th century when Korean potter Yi Sam-pyeong discovered porcelain stone at Mount Izumi. Kilns in the Hizen province produced exquisite underglaze blue and overglaze enamel wares, eventually captivating European royalty through East India Company exports. Traditional workshops relied on generational secrets for enamel firing and form construction.

Condition & Value

Appears to be in remarkably sound condition with light surface wear, minor kiln pitting, and slight darkening on the peg feet consistent with age. No major cracks or restorations visible in photos. Values depend heavily on verifying whether this is an authentic 18th/19th-century Edo period piece or a later Meiji revival piece.

  • Better-than-average condition for the category
  • Broader demand rises when presentation and finish feel intact

Concerns

  • Decorative-only demand limits the ceiling
