Nonko (also known as Donyu) was Raku Kichizaemon III (1599-1656), famed for his series of seven chawan (Shichishu). This kuroraku chawan is inspired by one of these, a chawan entitled "Chidori" wading bird, because the unglazed areas on the front resemble the bird's footprints.

Comes with a signed wooden box.
Handcrafted in Kyoto, Japan by Sasaki Shoraku III
