(Biography) Koyo Kumagai (15th generation) (1912-1992) Born in Akaike Town, Tagawa District, Fukuoka Prefecture (present-day Fukuchi Town), as the 15th generation of the Kumagai family, who revived Ueno ware in the late Meiji era. After graduating from Saga Prefectural Arita Technical High School, he honed his skills under his father, Ryuho. During the war, he engaged in pottery production in Manchuria (present-day northeastern China) due to military service. He received an award at the National Ceramics Competition in 1953. In 1964, he was selected for the Japan Traditional Crafts Exhibition for the first time, and was repeatedly selected from 1966 onwards. In 1969, he received the Excellence Award at the 1st Kyushu Ceramics Exhibition. He consistently pursued pottery in line with the tradition of Ueno ware as tea pottery, and was particularly skilled in making tea caddies (chaire). #KoyoKumagai #YasuokiKumagai #GenTakatsuru #JunichiTakatsuru #TakahisaToi #KozanTakada #EnshuSevenKilns #OldUenoWare #FolkCraft #UenoWare #Omotesenke #Urasenke #FukuokaPrefecture #Chawan #TeaCeremonyUtensils
