Tosa school
of Japanese painting was founded in the early Muromachi period (14th–15th centuries), and was devoted to "yamato-e", paintings specializing in subject matter and techniques derived from ancient Japanese art, as opposed to schools influenced by Chinese art, notably the Kanō school (狩野派). Tosa school paintings are characterised by "areas of flat opaque colour enclosed by simple outlines, where drawing is precise and conventional", with many narrative subjects from Japanese literature and history. However, by the 17th century both Tosa and Kanō artists broadened their range, and the distinction between these and other schools became less clear.
