priest and painter, regarded as the first of the long line of Japanese Zen Buddhist priests who painted in the Chinese-inspired suiboku (monochromatic ink painting) style.

Josetsu was associated with the Shōkoku-ji (in present Kyōto), where his pupil, the prominent painter Tenshō Shūbun (flourished early–mid-15th century) also resided. Josetsu's most important work is an ink landscape painting, “Catching a Catfish with a Gourd.” It was painted c. 1413, commissioned by Ashikaga Yoshimochi, the 4th Muromachi shogun and a disciple of Zen. It is one of the earliest suiboku paintings in Japan. The subject is Zen inspired; the soft ink-wash technique reflects the influence of Mu Ch'i Fa-ch'ang, a 13th-century Chinese Zen Buddhist painter whose style was widely emulated by the Japanese priest-painters. Josetsu is also believed to have done the boldly executed group portrait of Buddha, Lao-tzu, and Confucius, “The Three Teachers,” located in the Ryōsoku-in monastery, Kyōto.
