Japanese government official and renga (“linked-verse”) poet of the early Muromachi period (1338–1573) who is best known for refining the rules of renga composition.

Yoshimoto's father was kampaku (chief councillor) to the emperor Go-Daigo. Yoshimoto also served Go-Daigo, but after the mid-1330s he gave his allegiance to the emperors of the “northern” court. His first writings on linked-verse composition appeared in 1345 and were later put out in revised form as Renri hishō (roughly, “A Secret Selection of Renga Principles”). With the assistance of the poet Gusai (Kyūsei), Yoshimoto compiled Tsukuba-shū (1356), one of the first collections of renga (which were also called tsukuba at that time). In 1372 he and Gusai completed Ōan shinshiki (“New Rules of the Ōan Era”; also called Renga shinshiki), his most important work. Among his other treatises on renga composition is Tsukuba mondō (1372; “Questions and Answers on Renga”).
