According to the Hon'ami gyōjōki, a biography of Hon'ami Kōetsu that his grandson Hon'ami Kōho compiled, Kōetsu began creating ceramics after Tokugawa Ieyasu bestowed land at Takagamine, north of Kyoto, on him in 1615 (Genna 1). Assisted by the second- and third-generation heads of the Raku clan, Jōkei and Dōnyū, who produced Raku ware, Kōetsu learned to prepare glazes and fire his work. He worked, however, in a free style not constrained by the Raku tea bowl form. This red Raku glazed tea bowl, with its plumply rounded, rather squat shape, is somewhat distorted from being hand formed; with its shallow foot, which is somewhat sunk into the body, it perfectly suits its name, Jukushi: "ripe persimmon."
