Imao Keinen (1845 – 1924) was an eminent Japanese painter and print designer, recognized for his notable influence on Japanese art in the late 19th and early 20th centuries. He gained widespread acclaim as a key figure in the shin-hanga ("new prints") movement, which aimed to rejuvenate traditional Japanese woodblock printing by incorporating contemporary techniques and perspectives.

Keinen's artwork is esteemed for its meticulous portrayals of nature—particularly birds and flowers—characterized by refined colors and exacting lines. His prints frequently embody a harmonious blend of traditional motifs with innovative elements, which contributes to their high value among both collectors and art lovers in Japan as well as abroad.

In 1904, in acknowledgment of his artistic mastery, Imao Keinen was named an Imperial Household Artist. This distinguished honor, bestowed by the Japanese imperial family, recognized artists who exhibited exceptional talent and had made significant contributions to the nation's cultural legacy.

Keinen's influence continues to be felt today, as his paintings and prints still enchant viewers with their graceful elegance. His creations not only highlight the achievements of the shin-hanga movement but also provide insight into the evolving artistic landscape of Japan during a time of major cultural change.
