Isoda Koryūsai was a prominent Japanese ukiyo-e artist of the Edo period. Originally a samurai, he abandoned his warrior status and devoted himself to painting and printmaking in Edo (present-day Tokyo).

Active mainly during the 1770s and 1780s, Koryūsai was one of the most important artists of the kōban print format and was especially known for his elegant depictions of beautiful women (bijin-ga), courtesans, actors, birds, and landscapes. His style was influenced by Suzuki Harunobu, but he developed a more mature and refined approach, characterized by graceful compositions, subtle colors, and delicate line work.

In 1782, Koryūsai was granted the honorary title Hōgen by the Buddhist clergy, an exceptional recognition for an ukiyo-e artist. He later turned increasingly toward the study of nature, producing highly acclaimed kachō-ga (bird-and-flower prints), which are considered among the finest examples of Edo-period naturalistic imagery.

Today, Koryūsai is regarded as one of the great masters of ukiyo-e, and his works are held in major international collections
