Adachi Ginkō was a Japanese artist best known for his prints in the ukiyo-e style as a member of the Utagawa school. He worked in a variety of genres, including portraits of beauties and actors, landscapes, book illustrations, and satirical works, and produced a large number of triptychs of contemporary events. His most successful work was his Pictorial Outline of Japanese History series of triptychs in the late 1880s. He was jailed and fined in 1889 for caricaturing the Meiji Emperor.
