The chawan, from cha the tea and wan the bowl, is the bowl used for the preparation and consumption of matcha during the tea ceremony, the cha no yu or sadô in Japan. Its size and shape allow for easy whipping of the matcha.
The chawan, the central object of the cha nu yu, gives rise to many artistic creations with a variety of styles that have succeeded one another over the centuries. Among the most famous are the famous raku produced from generation to generation since the 16th century. Raku Kichizaemon XV, 15th generation, born in 1949 in Kyoto, current descendant of Chôjirô (1516-1589) founder of the raku-yaki style, continues to make this art of raku live with a contemporary approach.
I invite you to watch this video on his art and approach:
