Ohara Koson was a Japanese painter and woodblock print designer of the late 19th and early 20th centuries, at the forefront of shinsaku-hanga and shin-hanga art movements.

Shin-hanga was an art movement in early 20th-century Japan, during the Taishō and Shōwa periods, that revitalized the traditional ukiyo-e art rooted in the Edo and Meiji periods. It maintained the traditional ukiyo-e collaborative system where the artist, carver, printer, and publisher engaged in division of labor, as opposed to the parallel sōsaku-hanga movement.
