His work is defined by a restrained palette and a sense of calm. Unlike many of his contemporaries who used bold tones, Eishi preferred indigo, lilac, yellow, and grey. He avoided harsh colours, focusing instead on a clean aesthetic. He often created mitate-e, or parody prints, which reimagined classical Japanese literature in contemporary settings. His series based on the Tale of Genji and the Tale of Ise replaced ancient courtiers with fashionable women of the Edo period. These compositions combined his formal training in the Kano school with the popular appeal of bijin-e, or pictures of beauties.

Modern collectors value Eishi for his clean lines and the serene atmosphere of his compositions. His prints, such as Pleasure Boats on the Sumida River or his portraits of the Oiran Segawa, avoid the visual clutter found in later woodblock movements. The use of mica or glitter-dust backgrounds in his okubi-e adds a subtle texture that translates well to high-quality art prints. His ability to balance classical themes with the fashion of his time makes his work a sophisticated choice for interior spaces.
