Japanese Kutani Porcelain Plate Fragment or Backmark

This image features the underside of a porcelain plate, specifically highlighting a central red and gold manufacturer's mark indicating a Japanese Kutani origin. The ceramic material is a bright, high-fired white porcelain with an even, translucent glaze. Centered on the back is a distinctive ruddled orange-red (iron red) rectangular seal, hand-painted with two or three stylized gold kanji characters. The characters are likely 'Kutani' or a specific maker's name from the Ishikawa prefecture. The base shows a raised circular foot rim that appears slightly unglazed and reveals a smooth, fine-grained white clay body. There is a visible faint yellowish staining or discoloration surrounding the central mark, likely caused by mineral deposits or moisture over time. A small black production speck (pitting or iron spot) is visible near the bottom edge. Based on the style of the hand-painted overglaze mark, this piece likely dates to the Late Meiji or Taisho periods (circa 1890–1920), a time when Kutani ware was heavily exported. The craftsmanship is of high quality, as evidenced by the thinness of the porcelain and the precision of the calligraphic mark.
