Haboku sansui (Broken Ink Landscape) is a splashed-ink landscape painting on a hanging scroll, made by the Japanese artist and Zen Buddhist monk Sesshū Tōyō in 1495, during the Muromachi period. It was presented by Sesshū to his pupil Josui Sōen, who wanted a physical demonstration that he had studied under Sesshū. Sōen travelled with the scroll to his home in Kamakura, stopping in Kyoto, where six Zen monks added poems to it. The work is designated a National Treasure of Japan, and is held by the Tokyo National Museum.Painting credit: Sesshū Tōyō
