Founder of the Miyagawa school, he and his pupils are among the few ukiyo-e artists to have never created woodblock prints.
Chōshun trained under artists of the Tosa and Kanō schools, as well as under the master of early ukiyo-e, Hishikawa Moronobu.
His figures have a soft, warm femininity about them, and Richard Lane considers his coloring among the best in all of ukiyo-e art.
Though many of his pieces are clean ones of courtesans, Chōshun and his students also produced a great number of works of shunga (erotic paintings).
In 1751, a few years before his death, Chōshun was commissioned by an artist of the Kanō school to perform some restoration work at the Nikkō Tōshō-gū.
