Overview
This exquisite set of four lobed square porcelain bowls features intricate underglaze cobalt blue (sometsuke) decoration, including dense geometric diaper borders, floral medallions, and scrolling tendrils. The undersides bear apocryphal six-character Ming dynasty Chenghua marks ('Da Ming Chenghua Nian Zhi'), a traditional sign of honor and high ceramic ambition used by Edo-period Arita potters.
Story
Arita potters during the Edo period routinely inscribed high-quality porcelain with prestige Chinese dynasty marks to honor classical traditions. These square bowls were designed for formal Kaiseki banquets, where varied dish shapes complemented specific culinary courses.
Maker / Origin
Crafted in the famed kilns of Arita, Japan's porcelain heartland, these pieces reflect the legacy of Ko-Imari (Old Imari) production. Kiln masters combined natural porcelain stone from Izumiyama with cobalt pigment imported or refined locally, creating wares shipped through the port of Imari across Japan and worldwide.
Condition & Value
Small visible flea bites or foot rim chips are present on the underside foot ring of at least one bowl, consistent with age and use. Minor rim wear reduces top-tier value slightly, but overall the set retains vibrant glaze and color clarity.
