Overview
This is a fine Japanese porcelain deep display dish executed in the famed Iro-Nabeshima enamel tradition by the workshop of the Living National Treasure lineage Imaizumi Imaemon (likely the 12th or 13th generation). It features dynamic swirling underglaze blue waves adorned with floating overglaze iron-red and polychrome blossoms (Ikada-zakura or cherry blossom rafts motif).
Story
For over three centuries, the Imaemon family guarded the secret overglaze enameling techniques reserved strictly for the Nabeshima samurai lords, creating imperial-grade porcelain never meant for the public eye.
Maker / Origin
The Imaizumi Imaemon lineage served as the exclusive akae-shi (red overglaze master enameler) for the Nabeshima clan's official kiln during the Edo period. After the fall of the samurai shogunate, the family preserved these legendary secret recipes, with both the 12th, 13th, and 14th generations recognized as Living National Treasures (Important Intangible Cultural Properties) of Japan.
Condition & Value
Appears to be in very good vintage condition with clean enamels and intact foot ring; the original wooden tomobako shows light age patina and natural wood grain aging. Excellent condition with tomobako preserves strong collector value.
