Japanese scholar and author of waka and renga (“linked-verse”) poetry during the late Muromachi period (1338–1573). Along with two other renga masters, he composed Minase sangin hyakuin (1488; Minase Sangin Hyakuin: A Poem of One Hundred Links Composed by Three Poets at Minase).

Little is known of his early life, but at some time he became a student of the Buddhist monk and poet Iio Sōgi. In early 1488 Shōhaku, Sōgi, and another student, Sōchō, met at Minase, a village between Kyōto and Ōsaka, and wrote Minase sangin. The poem, which was written at the height of the renga's popularity, is considered to be one of the best examples of the genre.

Shōhaku assisted Sōgi in editing Shinsen tsukubashu (1495; “Newly Selected Tsukuba Collection”), an anthology of renga that included revised rules for their composition. His own works include Ise monogatari shōbunshō, a commentary on the Tale of Ise; and Shōhaku kōden, a scholarly treatise on renga.
