was a Japanese Zen Buddhist monk and painter of the Muromachi period.
Shà «bun was born in the late 14th century in à Âmi Province and became a professional painter around 1403. He settled in Kyoto, then the capital city. He became director of the court painting bureau, established by Ashikaga shà Âguns, which consisted of influential art patrons. He was chosen by the members of the diplomatic mission to Joseon in 1423.
Shà «bun is considered to be the founder of the Chinese style of suiboku ink painting in Japan. He was influenced by Chinese landscape painters Xia Gui and Ma Yuan.
Throughout his life, Shà «bun was associated with the Zen Buddhist temple, Shà Âkoku-ji. Early in his career, he studied painting there under Josetsu, a Chinese immigrant who became the father of the new Japanese ink painting tradition. Under Josetsu's influence, Shà «bun started studying Chinese Song dynasty painting by masters such as Xia Gui and Ma Yuan; consequently, Shà «bun's style was an intermediate step between early Japanese artists who imitated Chinese models very closely, and later artists, who developed a national style. Later in life, Shà «bun became overseer of buildings and grounds at Shà Âkoku-ji.
In the 1440s he taught the young Sesshà « Tà Âyà Â, who became his best pupil and the most highly regarded Japanese artist of his time. Another important pupil may have been Kanà  Masanobu, who succeeded Shà «bun as the chief painter of the Ashikaga shogunate, and also founded the Kanà  school of painting.
Shà «bun's most well-known painting, designated as a National Treasure in Japan, is Reading in a Bamboo Grove, now kept in the Tokyo National Museum. The same museum houses a few other works attributed to Shà «bun, among them a pair of titled . Two more pairs of folding screens depicting landscapes of the four seasons are held by the Seikadà  Bunko Art Museum. As with many Japanese and Chinese artists of this and earlier periods, many works survive that are attributed to Shà «bun, but only for a few is this attribution secure. Contemporary accounts describe Shà «bun as a very versatile artist, yet the only extant works with the authorship issue resolved are landscapes.
