Shunshō changed the direction of Japanese ukiyo-e by introducing realism to actor portraits. Earlier artists used generic facial features for every subject. Shunshō captured the specific physical traits of Kabuki performers instead. He frequently utilised the narrow hosoban format for these depictions. His work in the 1770 collection, A Picture-book of Stage Fans, demonstrated his ability to fit expressive characters into restrictive shapes. He also produced prints of sumo wrestlers, including Tanikaze Kajinosuke, and illustrated classical literature like the Tales of Ise.

Modern collectors value Shunshō for his clean lines and the historical accuracy of his theatrical subjects. His prints, such as Ichikawa Yaozo II as Soga no Goro, provide a clear view of the costumes and poses of the Edo period stage. The compositions are balanced and lack unnecessary clutter. These works offer a sophisticated aesthetic for contemporary interiors. His focus on individual personality rather than idealised forms makes his portraits feel immediate and human.
