Yamamoto Shoun (December 30; 1870 - May 10; 1965); who was also known as Matsutani Shoun; was a Japanese print designer; painter; and illustrator. He was born in Kochi into a family of retainers of the Shogun and was given the name Mosaburo. As a teenager; he studied Kano school painting with Yanagimoto Doso and Kawada Shoryu. At about age 17; he moved to Tokyo; where he studied Nanga painting with Taki Katei. At 20 years of age; he was employed as an illustrator for Fugoku Gaho; a pictorial magazine dealing with the sights in and around Tokyo. In his latter career; Shoun primarily produced paintings. He died in 1965; at the age of 96.

In addition to his magazine illustrations; Shoun is best known for his woodblock prints of bijin or 'beautiful women'; especially imasugata a kind of precursor to the 'moderngirls / moga' movement of the 1920s and 1930s. Shoun is considered a bridge between the ukiyo-e and shin hanga schools. His career spans the Meiji (1868-1912); Taisho (1912-1926) and Showa (1926-1989) periods.
