Overview
A refined Japanese porcelain five-inch dish (gosun-zara) decorated in the classic Iro-Nabeshima palette of underglaze cobalt blue and overglaze polychrome enamels. The composition depicts three tied gourds (hyotan) against a delicate underglaze blue Seigaiha (stylized ocean wave) ground, framed by an iron-red rim.
Story
Centuries ago, the Nabeshima clan guarded their porcelain kilns in a secluded mountain valley like state secrets. Gourds symbolized good fortune and protection, presented exclusively as elite diplomatic gifts to the Shogun.
Maker / Origin
Nabeshima ware was produced at the official clan kilns at Okawachiyama under strict secrecy and supreme quality control for the Saga Domain lords. Unlike commercial Imari porcelain exported abroad, Nabeshima pieces were never sold to the public and were strictly reserved for the Shogunate and aristocratic daimyo gifts.
Condition & Value
The front surface presents in excellent condition with bright, well-preserved overglaze enamels and no visible chips, cracks, or enamel flaking. Pristine enamel preservation significantly supports collector appeal.
