Overview

An elegant, square-sided porcelain vase decorated in the refined Iro-Nabeshima style with the traditional 'Three Friends of Winter' (Sho-Chiku-Bai) motif. The piece features a pristine white glaze serving as a canvas for underglaze blue, overglaze red, green, and yellow enamels, complete with a delicate flying bird on the side panel.

Story

During the Edo period, Nabeshima ware was so exclusive that it was forbidden for commoners to own, reserved strictly as tribute gifts for the Shogun. This mid-century vase revives that aristocratic legacy, using the 'Three Friends of Winter' motif to symbolize resilience and longevity.

Maker / Origin

The underside bears the hand-painted blue underglaze mark of 'Kozan' (魯山), a respected kiln operating in the historic Arita region. Kilns like Kozan specialized in keeping the highly technical, imperial-grade Nabeshima decorating traditions alive for modern collectors, maintaining strict standards of porcelain purity and enamel clarity.

Condition & Value

The vase appears to be in excellent vintage condition with no visible chips, cracks, or crazing. The enamel colors remain bright and unfaded, and the foot shows only minor, expected shelf wear. Excellent condition like this helps secure the higher end of the valuation range.

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
