Onchi Koshiro

Onchi Koshiro (1891-1955) was a Japanese artist widely regarded as the father of modern Japanese abstract printmaking and one of the founding figures of the sosaku-hanga (creative prints) movement. A visionary who challenged the centuries-old collaborative system of Japanese woodblock production, Onchi championed the radical idea that the artist should be the sole creator of a print — designing, carving, and printing the work entirely by hand. His pioneering abstract compositions, lyrical portraits, and experimental techniques opened new expressive possibilities for the woodblock medium and profoundly influenced generations of Japanese printmakers who followed him.

Born on August 2, 1891, in Tokyo, Onchi grew up in a cultured household that valued both traditional Japanese arts and Western learning. His father was an official in the Imperial Household Agency, and young Koshiro was exposed from an early age to the finest examples of Japanese art and culture. He attended the Tokyo Fine Arts School (Tokyo Bijutsu Gakko, now Tokyo University of the Arts), where he studied Western-style painting and developed a strong foundation in drawing, color theory, and composition. However, it was during his student years that he first encountered the ideas that would lead him to printmaking and, specifically, to the sosaku-hanga philosophy.

The sosaku-hanga movement had its intellectual roots in the belief, promoted by artists and critics in the early twentieth century, that a true work of art must be the product of a single creative vision. This stood in direct opposition to the traditional ukiyo-e system, still championed by the shin-hanga movement, in which an artist designed an image that was then carved and printed by separate teams of specialized craftsmen. For Onchi and his sosaku-hanga colleagues, this division of labor diluted the artistic integrity of the final print. They argued that only when an artist personally controlled every stage of production — from initial concept through carving and printing — could the resulting work be considered a genuine expression of individual creativity.

In 1914, Onchi and two fellow students, Fujimori Shizuo and Tanaka Kyokichi, founded the journal "Tsukuhae" (Moon Reflections), which became an important platform for sosaku-hanga ideas. The journal published original prints by the three founders and other like-minded artists, along with critical essays that articulated the theoretical underpinnings of the creative print movement. This publication marked the beginning of Onchi's lifelong commitment to promoting sosaku-hanga as a modern artistic practice equal in stature to painting and sculpture.

Throughout the 1920s and 1930s, Onchi developed his artistic practice in several directions simultaneously. He produced figurative prints — landscapes, still lifes, and portraits — that demonstrated the expressive potential of the artist-as-sole-creator approach. These works, while representational, already showed the tendency toward simplification, bold design, and emphasis on the physical qualities of the medium that would characterize his mature style. He experimented with different papers, inks, and printing techniques, exploring the unique marks that could be achieved when the artist directly engaged with the materials of printmaking rather than delegating technical execution to specialists.
