Japanese painter of the ukiyo-e style of popular, colourful art based on everyday life. He was the founder of the Miyagawa school of painting.

Chōshun went to Edo about 1700 and fell under the influence of the works of Hishikawa Moronobu (d. c. 1694), who established the basic ukiyo-e style in both painting and wood-block printing. Chōshun concentrated on painting, rather than on print designs, and drew his pictures with fluid lines and subtle colouring. He was also adept at depicting crowds.

At one time, when some painters were commissioned to repair the family shrine of the Tokugawa shogunate at Nikkō, the artist Kanō Shunga invited Chōshun, famous as a colourist, to participate. But in a dispute over fees, Chōshun was insulted and physically hurt at Shunga's home. Chōshun's son and pupils retaliated by attacking and wounding members of the Kanō clan. Chōshun was then expelled from Edo for two years.

Among Chōshun's notable paintings are the picture scroll “Engeki zukon” (“Theatre Scenes”) and “Fūzoku zukan” (“Panorama of Contemporary Life”).
