Chōkōsai Eishō was a Japanese ukiyo-e artist. He also used the name Shōeidō.
Eishō's personal details are unknown. His works that remain show a practised skill, so it is likely that they appeared after years of apprenticeship. He is the most prominent student of Eishi and had a prolific output; nearly 200 of his works remain—more than any other student of Eishō's. He produced at least twenty print series published by fourteen publishers, in particular for Yamaguchiya Chūsuke. The majority of his work appeared between c. 1792 and c. 1799.
Eishō's work is assumed to have been in competition with that of Utamaro, who was known for his vertical ōkubi-e bust prints in the bijin-ga genre of portraits of beautiful women. Most of Eishō's prints were in the same format. He depicted his subjects in an elegant, slender-proportioned style. His most representative prints are considered to be those from the seriesKakuchū bijin kurabe. The series depicts actual courtesans from the Yoshiwara pleasure quarters, and the backgrounds were treated with glimmering mica. Eishō contributed twenty of the twenty-four print designs; the remainder were by fellow Eishi students Eiri and Eiu.
