This is a Kutani ware plate, a traditional Japanese color-painted porcelain produced in the southern part of Ishikawa Prefecture. Kutani ware's most distinctive feature is "uwazuke" (overglaze painting), where outlines are drawn in black called "gosu," and then five colors known as "Kutani Gosai" (green, yellow, purple, dark blue, and red) are thickly applied on top. The vivid and bold pictorial expression seen in the image is one of the typical painting styles of Kutani ware. Due to its high artistic value, it is highly regarded overseas as "Japan Kutani" and has become a collector's item with artistic value. It is a traditional craft representing Ishikawa Prefecture, boasting a history of approximately 370 years. This item has been stored in a private home, so we ask for your understanding.
