Works of Ushinoto Ware were produced from the end of the Edo period (1615-1868). Yoshida first learned of these ceramics through the Gorohachi tea bowl made by the Ushinoto Ware Kiln, and immediately began working on designs for his "new folk crafts." He was assisted by key figures in the Mingei Movement including Yanagi Muneyoshi (Soetsu), Hamada Shoji, Kawai Kanjiro, and Bernard Leach. Through this joint effort, many best-selling items were created.
