Historical Context & Maker Details
- The Manufacturer: This mark belongs to Fukueidō (福栄堂), a highly influential Kutani porcelain merchant and workshop founded in Kanazawa in 1909 by Kuwata Yojūrō. Fukueidō was renowned for expanding the reach of Kutani ware across Japan and was notably a pioneer in exploring the use of modern electric kilns to refine glaze firings.
- Dating This Cup: Fukueidō operated dynamically under this specific lineage from 1909 until 1935, before the trademark brand was passed on to a close associate. Based on the style, standard porcelain composition, and the workshop timeline, this covered teacup was produced during the Taisho period to the early Showa period (circa 1910s–1930s).
- Craftsmanship Value: Finding a matched covered cup with a distinct workshop mark like Fukuei is wonderful. It confirms that the piece is a genuine, early 20th-century historical example of the Kyoto-inspired Mokubei style revival, rather than a generic modern replica.
