Shubun (shōō´bōōn´), fl. 1st half of 15th cent., Japanese painter and Zen Buddhist priest. He studied under Josetsu, and became the central figure in the renaissance in Japan of the Chinese style of ink painting. Shubun and Sesshu, who may have been his pupil, are regarded as the two greatest masters of ink painting of the Muromachi period. There are many landscape paintings in ink attributed to Shubun, which vary in quality and style. Examples are in the Fujiwara collection and the Seikado Foundation.
