The document discusses the influence of Japanese art, known as Japonisme, on Western art in the late 19th century. It began when trade opened with Japan in 1854, exposing Western artists to woodblock prints, which were popularized in Paris exhibitions and shops in the 1860s. Artists admired the prints' flatness, asymmetry, and emphasis on nature over symmetry. Many Impressionist and Post-Impressionist artists, such as Manet, Degas, Van Gogh, and Gauguin, were influenced by these styles and incorporated elements of them into their own works.
