Overview
An exquisite Japanese porcelain bowl decorated in underglaze cobalt blue, featuring a dramatic seigaiha (ocean wave) pattern populated by mythical qilin and sacred tortoises. The interior rim is bordered with geometric karakusa (vines) and tortoise-shell diaper patterns, centering a stylized floral medallion at the well.
Story
Created in the 1700s, this bowl survived centuries of use in Japanese tea ceremony culture. The design features the qilin and tortoise, ancient symbols of peace and longevity, riding over a sea of stylized waves. It represents a time when Japanese porcelain makers mastered underglaze cobalt to rival Chinese imports.
Maker / Origin
Produced in the historic kilns of Arita, the birthplace of Japanese porcelain. While the individual artisan remains anonymous, the piece bears a 'Fuku' (good fortune) mark on the base, a common mark of high-quality workshop production during the Edo period. These craftsmen worked under the strict supervision of the Saga Domain, ensuring exceptional quality control.
Condition & Value
The bowl appears to be in excellent antique condition with no visible chips or major cracks, which is remarkable for its age. There is a natural firing line or glaze contraction on the underside of the foot rim from the kiln process, which is typical of Edo-period porcelain and does not detract from its value.
